Basic Info

What is 2-AcrylaMide-2-Methylpropanesulfonic acid?

2-Acrylamide-2-methylpropanesulfonic acid (AMPS for brief) is a plastic monomer with a sulfonic acid team. It is a white crystalline powder with a melting point of 185 ° C. It has a somewhat sour preference and strong Hygroscopicity; if damp, AMPS monomer will certainly polymerize on its own. Its liquid solution is acidic, soluble in dimethylamide, partially soluble in methanol and ethanol, and also insoluble in acetone; AMPS has excellent thermal security, as well as its disintegration temperature level can reach up to 210 ° C. The decay temperature level of its sodium salt homopolymer as much as 329 ° C. In liquid solution, the hydrolysis price is slow-moving, and the sodium salt solution has the best hydrolysis efficiency under the condition of high pH value. Under acidic conditions, the hydrolysis resistance of its copolymer is a lot more than that of polyacrylamide.

2-AcrylaMide-2-Methylpropanesulfonic acid Uses

  • AMPS is made use of to prepare superabsorbent material, which can improve the ability of the resin to absorb seawater.
  • AMPS is utilized as a customized monomer for acrylic fiber, which can dramatically improve the spinnability, dyeability, antistatic home, abrasion resistance, whiteness and also transparency of the fiber.
  • The homopolymer of 2-acrylamido-2-methylpropanesulfonic acid as well as the copolymer of AMPS as well as various other monomers are extensively made use of in fabrics, printing and dyeing, plastics, finishes, papermaking, wastewater treatment, daily chemicals, natural leather and oil field chemistry, etc field.
  • 2-Acrylamido-2-methyl-1-propanesulfonic acid (AMPS) has a polymerizable vinyl group and a hydrophilic sulfonic acid group in the molecule, which can be integrated with water-soluble monomers such as acrylonitrile and acrylamide, benzene, etc. Copolymerization of water-insoluble monomers such as ethylene and also vinyl chloride. Present hydrophilic sulfonic acid groups into polymers to make fibers, films, etc hygroscopic, water-permeable, and conductive. Can be used in paper market and also wastewater treatment. Made use of as paint modifier, fiber modifier and clinical polymer, etc 2-acrylamido-2-methylpropanesulfonic acid can be homopolymerized or copolymerized. 2-acrylamido-2-methylpropanesulfonic acid can be used as a medium for polymerization with an ordinary heat of polymerization of 22 kcal/cool amide in water.

Application of 2-AcrylaMide-2-Methylpropanesulfonic acid

The architectural formula of 2-acrylamide-2-methylpropanesulfonic acid (AMPS) has strong anionic, water-soluble sulfur teams, secured amide groups and unsaturated dual bonds, that make it have exceptional thorough buildings. It has great complexation, adsorption, organic activity, surface area task, hydrolytic stability and thermal security. The unique molecular structure of AMPS enables it to go through both copolymerization and also enhancement reactions, as well as is commonly utilized in oilfield chemistry, water therapy, synthetic fibers, printing as well as dyeing, plastics, water-absorbing coatings, papermaking, biomedicine, magnetic products, cosmetics and polymers. Carboxylic acid superplasticizer production as well as other areas.

The molecular structure of AMPS has carboxylic acid groups with scale-inhibiting as well as spreading residential properties and also strong polar sulfonic acid groups, which can enhance calcium tolerance and have significant scale-inhibiting results on calcium phosphate, calcium carbonate, zinc range, etc in water, and also distribute Exceptional efficiency. Intensifying of AMPS as well as organic phosphine, the collaborating impact is noticeable. AMPS is especially appropriate for water top quality with high pH, high alkalinity as well as high firmness. It is one of the most perfect antiscaling as well as spreading representatives for high focus multiple operation.

Preparation of 2-AcrylaMide-2-Methylpropanesulfonic acid

A kind of preparation method of 2-acrylamido-2-methylpropanesulfonic acid is finished according to the following steps:

  1. First add 50 ml of acrylonitrile to the 1# reactor as a pre-reaction solution, turn on the agitator, and the stirring speed is 120-160r/min, and use the cooling liquid to reduce the temperature in the 1# reactor to 2-6°C.
  2. After the temperature in the 1# reactor drops to 2~6°C, add acrylonitrile and oleum into the 1# reactor at a uniform speed, and the reaction residence time is 1~1.5h. When the reaction liquid reaches 1# When the overflow port of the reactor is used, the overflow liquid flows into the 2# reactor.
  3. When the overflow liquid flows into the 2# reactor, pass the vaporized isobutene into the 2# reactor at a constant speed, the reaction residence time is 2.5~3h, the reaction temperature is 37~42℃, and then continuously overflows to the sedimentation crystallization kettle After cooling at medium temperature and drying under reduced pressure by centrifugation, 900.5g of crude product of 2-acrylamido-2-methylpropanesulfonic acid was obtained; the product purity was 97.7% (detected by liquid chromatography).
  4. Add the crude product of 2-acrylamido-2-methylpropanesulfonic acid and 2700g of acetic acid into the recrystallization kettle, raise the temperature of the recrystallization kettle from room temperature to 80°C within 40 minutes, and then cool down to 20°C at a uniform speed , kept at a temperature of 20° C. for 1 h, and dried by centrifugation to obtain 767.2 g of 2-acrylamido-2-methylpropanesulfonic acid.

The water content of acrylonitrile described in step 2 is 0.02%; Free state SO in the oleum described in step 2 The content is 5%; The feed rate of acrylonitrile described in step 2 is 169.26g/h; The feed rate of the oleum is 24.5g/h; the feed rate of the vaporized isobutylene described in step 3 is 24.5g/h.

The yield of the method is 85.2% (calculated as crude 2-acrylamido-2-methylpropanesulfonic acid), the product purity is 99.9% (detected by liquid chromatography), and the melting point is 184.1°C.
