Product Introduction
2-Methylpropanesulfonic acid-2-polyacrylamide, referred to as AMPS/ATBS, was first industrialized by Lubrizol Petroleum Company in the United States in the early 1970s with a two-step method. In the late 1970s, Japan's Nitto Chemical Company improved the two-step process in the United States and realized industrial production with one-step method.
Physical Properties
Appearance:Off-white crystal or powder
Melting point:185℃(Partial decomposition)
Odor:Has a sour taste
Hygroscopicity:It has strong moisture absorption, so it must be packaged in moisture-proof containers and stored in a dry place. If water is absorbed, polymerization will occur.
Product form:Powdered, granular, (liquid) sodium salt; currently, powdered products are more common on the market, but sodium salt products and granular products are the development trend of the industry, and foreign markets mainly demand granular products and sodium salt.
Application
AMPS is widely used in textiles (spinning, dyeing), plastics, papermaking, coatings, sewage treatment and oil extraction and other industrial production, manufacturing excellent antistatic agents, dyeing agents, dispersants, water absorbing agents, flocculants, Foam stabilizer, special coating, oil field chemical agent, etc. At present, this product has been widely used in many fields in China, especially in the water treatment agent production industry. It has become the raw material for new technology products of many manufacturers. The polymer of this product has also attracted much attention in the field of oilfield three extraction, which is to increase the output of tertiary oil recovery. One of the indispensable raw materials; it has been widely used in the acrylic fiber production industry abroad, and domestic industry experts also have a consensus. After my country's entry into the WTO, the acrylic fiber industry must use the three products to meet challenges and upgrade products. In short, the extraordinary application value in various fields has been fully demonstrated and recognized. It is expected that the application in these fields will become more and more extensive, and the market demand and price are also worth looking forward to.
Water treatment field
One of the main uses of AMPS is to produce water treatment agents. At present, the research and production of this product in water treatment agents have been widely carried out in China, especially the research on organic phosphonic acid and carboxylic acid copolymer, which is the most widely used water treatment agent in industrial cooling water system. The developed POCA has the advantages of organophosphonic acid and carboxylic acid copolymer. Not only the mass fraction of phosphorus is low (<5%), it meets the requirements of environmental protection, and the introduction of sulfonic acid groups enhances its hydrophilicity and improves The ability to resist cationic precipitation improves its dispersion ability. Water treatment with current HEDP (organic phosphonic acid: hydroxyethylene diphosphonic acid), HPMA (carboxylic acid copolymer: hydrolyzed polymaleic anhydride), HS-312 (sulfonic acid copolymer), PBTCA (phosphonic anhydride), etc. Compared with other agents, POCA not only has good scale and dispersion performance, but also has certain corrosion inhibition performance, and the overall performance is better. In recent years, as countries in the world pay more and more attention to environmental protection, the treatment of various wastewater has also become particularly important. It is believed that the market demand for this product will increase year by year. At present, the application of AMPS in water treatment agents accounts for 1/3 of the world's output. AMPS homopolymers or copolymers with monomers such as acrylamide and acrylic acid can be used as sludge dehydrating agents for sewage purification; also used as scale removers and scale inhibitors for heaters, cooling towers, air purifiers and gas purifiers Agent; used as an antiseptic for iron, zinc, aluminum, copper and their alloys in a closed water circulation system. A large amount of literature data shows that using AMPS copolymer as a water treatment agent has the characteristics of less dosage and better effect than existing polyacrylamide water treatment agents.
Textile and dye industry
AMPS is an important monomer to improve the overall performance of some synthetic fibers, especially acrylic or acrylic fiber. Its dosage is 1% to 4% of the fiber, which can significantly improve the whiteness, dyeability, antistatic, and antistatic properties of the fiber. Breathability and flame retardancy. The modified acrylic fiber can be dyed in various colors, can increase the moisture absorption rate, make the acrylic cellulose closer to natural wool, can improve the spinning process, increase the spinnability, and enhance the luster, color and water absorption of acrylic products , Flexibility is also greatly improved. It is precisely because of these advantages that the monomer has been widely used in many acrylic fiber factories in the United States, Britain, Italy, and India.
At present, except for a few domestic manufacturers, AMPS acrylic fiber is not widely used. Generally, sodium methacrylic acid sulfonate and sodium styrene sulfonate are used as triple monomers, or triple monomers are not used at all, and only binary copolymerization (such as Anhui Anqing Acrylic Fiber Factory), so the quality of domestic acrylic fiber products is generally poor. Facing the fierce competition in the international acrylic fiber market, coupled with the gap between the quality and specifications of acrylic fiber in my country and foreign acrylic fiber, in order to enhance the competitiveness of enterprises, domestic acrylic fiber manufacturers have begun to actively investigate and demonstrate this technology.
Oil industry
Water-soluble polymers have important uses in the petroleum industry. They are widely used in many operations such as drilling, cementing, well completion and workover, and enhanced oil recovery (EOR). AMPS has a wide range of applications in the field of oilfield chemistry, covering the scope of drilling fluid treatment agents, oil well cement additives, acidulants, fracturing agents, completion fluids and workover fluid additives, water shutoff agents, tertiary oil recovery and flooding Agent, dispersant, oily sewage treatment agent, etc. The most common is the binary, ternary and multi-component water-soluble copolymers formed by AMPS and monomers such as acrylamide, acrylic acid, acrylonitrile, N-ethylpyrrolidone, and N,N-dimethylacrylamide. The terpolymer made of AMPS, methacrylic acid and acrylamide is used as cement admixture, which can play a good high-temperature retarding effect; the copolymer with N,N-dimethylacrylamide can be used as Oil well cement slurry fluid loss agent; the graft copolymer of AMPS, calcium lignosulfonate and acrylamide is a better cement slurry distribution agent or early strength agent, enhancer, etc.; AMPS and acrylic acid, tetrahydrobenzoic acid, wood Graft copolymers of sulfonic acid, etc. can be used to prepare drilling fluid dispersants and stabilizers with good calcium resistance, viscosity reducers, fluid loss additives, etc. In addition, the block copolymer of AMPS and N-vinylpyrrolidone can be used as a thickener for tertiary oil recovery. It will not be degraded under high temperature, high pressure and high shear conditions, and has good stability.
Studies have shown that the binary and terpolymers of AMPS and several monomers can be directly used in drilling fluids. Mixing appropriate amounts of such copolymers with low molecular weight and high molecular weight can greatly improve the performance of drilling fluids. As an effective modification monomer, AMPS has penetrated into polymer modification in various fields of oilfield chemistry, and to a large extent, it does solve the three most difficult problems of salt resistance, temperature resistance, and shear resistance. Subject. At present, people in the domestic oilfield chemistry community have begun to use AMPS in the synthesis of EOR polymers and drilling mud additives, and have achieved initial results. As an extremely important and non-renewable strategic resource, oil is attracting the attention of the world. With the depletion of oil resources, the difficulty of oil extraction becomes more and more difficult. This will surely promote the rapid development of the oil field chemical industry, thereby providing AMPS Huge market space.
(1) Oil well cement additives
The terpolymer prepared with AMPS, methacrylic acid and acrylamide is suitable for various salt cement slurries and can play a good high temperature retarding effect. The copolymer of AMPS and acrylic acid, the copolymer of AMPS and N,N-dimethylacrylamide and carboxymethyl hydroxyethyl cellulose introduced by Halliburton in the United States are used as oil well cement admixtures, which can effectively reduce cement High temperature fluid loss of slurry.
(2) Drilling fluid treatment agent
The graft copolymer of AMPS with acrylamide and starch, the copolymer of AMPS with acrylamide and N,N-dimethylacrylamide, the graft copolymer of AMPS with humic acid and acrylamide are used in freshwater drilling fluids and brine drilling fluids. , Both saturated brine drilling fluid and seawater drilling fluid have good fluid loss reduction, temperature resistance and salt resistance.
Clay dispersion and pollution caused by other factors often cause the viscosity of the drilling fluid to increase. At this time, a viscosity reducer is needed to control the rheology of the drilling fluid. The most commonly used drilling fluid viscosity reducer is iron chromium lignosulfonate (FCLS). The terpolymer of AMPS, acrylic acid and methacrylic acid is used as a drilling fluid viscosity reducer to replace FCLS, which not only retains the good salt resistance and temperature resistance of FCLS, but also overcomes the toxicity of FCLS. Studies have shown that terpolymers are more resistant to high-valent metal ions than binary copolymers.
(3) Completion fluid and workover fluid additives
The copolymer of AMPS, acrylic acid and itaconic acid can be used as a thickener for the preparation of seawater and salt water, which increases the viscosity of the completion fluid by more than 4 times, and has good thermal stability, which overcomes the viscosity reduction of traditional polymers in the salt water system.Shortcomings.
(4) Oilfield water treatment agent
AMPS homopolymers or copolymers formed with acrylic acid, acrylonitrile, acrylamide, etc. can be used as flocculants, sludge dehydrating agents and scale inhibitors for oilfield sewage treatment. The terpolymer composed of AMPS, acrylic acid and sodium styrene sulfonate launched by F. Goodrich has a good inhibitory effect on calcium sulfate scale and calcium phosphate scale, and the scale inhibition rate is over 97%. Literature data shows that using AMPS copolymer as water treatment agent has the characteristics of less dosage and better effect than existing polyacrylamide water treatment agents.
(5) Tertiary oil recovery agent
In the polymer enhanced oil recovery (EOR) operation, water-soluble polyacrylamide is currently used. Years of research work has shown that polyacrylamide polymers have the following shortcomings: poor shear stability, severe mechanical degradation during pumping, poor salt resistance, and sensitivity to mineralized water, especially polyvalent metal ions, resulting in a sharp decrease in viscosity in saline solution , Even precipitation, poor acid and temperature resistance. In the past 20 years, the modification of polyacrylamide has been widely carried out at home and abroad. The American Phillips Petroleum Company developed the copolymer of AMPS and acrylamide for tertiary oil recovery, which greatly improved the salt and temperature resistance of polyacrylamide.
In addition, the copolymer synthesized by AMPS is stable and has a lubricating effect in high concentrations of protic acid, and can be used in the acid fracturing process of oil and natural gas wells. At the same time, the copolymer of AMPS is used as a thickening agent for fracturing fluids. The performance is better than the currently used guar gum products, and it has the advantages of convenient use, suitable viscosity, high temperature resistance and high shear.
Paint industry
AMPS is used in the coating industry as a performance enhancer for coating modifiers, adhesives and finishing agents with excellent performance. Adding AMPS to acrylic cathodic electrophoretic coatings and water-soluble thermal curing coatings can promote the crosslinking and curing of the coating film during drying, so as to obtain a coating film with good gloss and other properties.
Paper industry
The copolymer of AMPS and other water-soluble monomers is an indispensable chemical in various paper mills. It can be used as a drainage aid, sizing agent to increase the strength of paper, and it can also be used as a pigment dispersant for color coatings. Water-soluble polymer containing AMPS, can be used as paper strength enhancer, refined pulp and filler utilization enhancer, slurry dispersant in the papermaking process of paper and other inorganic materials, paper drying peel enhancer, etc. During the production process, AMPS copolymers can be used to improve the retention rate of fillers and pulp debris, and to increase the dehydration rate of the slurry. Tests have shown that adding AMPS-containing water-soluble polymers to paper pulp as a strengthening agent significantly improves the relevant parameters of paper strength. At present, the application of foreign papermaking research has made great progress, and domestic research work has just started, mainly in the research of AMPS copolymers. In the future, the development and research of my country's papermaking auxiliaries will not be necessary for AMPS. The missing important modifying monomer.
Other industry
Because of the special structure of AMPS monomer, it is also widely used in other industries. In foreign countries, hollow fibers made by copolymerization of AMPS and acrylonitrile can be used for hemodialysis; polymers made by cross-linking AMPS and dimethyl ethylene acrylate can be used to make contact glasses; AMPS (or its salt) copolymerization The aqueous solution or ethanol solution of the substance can also be used as the adhesive for medical electrodes; because the homopolymer of AMPS feels good and does not harm the skin, it is often used as a lubricant and thickener in cosmetics and detergents; in ceramics and mineral processing technology There are also certain uses in phosphate ore. For example, AMPS copolymers can be used as thickeners for ceramic glazes and as dispersants in ceramic formulations; in the beneficiation process, high molecular weight AMPS copolymers can be used as flocculants for phosphate ore slurry. Medium molecular weight copolymers can be used as "red paste" flocculants; in addition, AMPS monomers have also begun to play a role in the photographic and electronic industries.
