What is AMPS used in wastewater treatment and what is it made of? Please help

2 acrylamido-2-methyl propane sulfonic acid (abbreviated as amps, also known as tert-butyl acrylamide sulfonic acid, is an acrylamide anionic monomer. Its structural formula is:

AMPS has a wide range of applications in oilfield chemistry, wastewater treatment, papermaking, textiles, plastics, printing and dyeing, coatings, leather, biomedical materials, magnetic recording materials, etc. Water treatment is one of the most important application areas for AMPS. The homopolymer of AMPS or copolymer with acrylamide, acrylic acid and other monomers can be used as a sludge dewatering agent for sewage purification; It can also be used as a descaler and scale inhibitor for heaters, cooling towers, air purifiers and gas purifiers; It is used as a preservative and metal surface treatment agent for iron, zinc, aluminum, copper and electrode alloys in a closed water circulation system.

Acrylic acid, maleic anhydride and AMPS terpolymer have excellent scale inhibition and dispersibility to calcium phosphate, and can be used as an antiscale dispersant for industrial circulating water. The literature shows that the use of AMPS copolymer as a water treatment agent has the characteristics of low dosage and better effect than the existing polyacrylamide water treatment agent.

AMPS is a fine chemical product with excellent properties such as polymerization, hydrophilicity, stability, hydrolysis resistance and salt resistance, and has a wide range of applications. In the research and application of AMPS polymers, in addition to transforming old products in traditional fields such as oilfield chemistry, synthetic fibers, and industrial water treatment, we continue to develop new products in depth; On the other hand, exploratory work is constantly being carried out in emerging fields such as biomedical materials. In recent years, China has been active in the research on the synthesis process and application of AMPS, especially in 1987, after the high-efficiency tertiary oil recovery auxiliary developed by the American cyanamide company with AMPS obtained the patent invention right in China, it has attracted the attention of Chinese chemists.

However, at present, there are few manufacturers in China, small scale, low production capacity, high cost, and applied research is only limited to water treatment and oilfield chemicals, and the research and application in other new fields are almost blank, so the development and utilization prospects of AMPS in China will be very broad.

AA AMPS is copolymerized with acrylic acid and 2-acrylamide-2-methylpropanesulfonic acid (AMPS).

This is a chemical substance, and I don't know how to synthesize it.

Product Name: amps

Chinese name : 2-acrylamido-2-methyl propane sulfonic acid

Molecular formula: C7H13NO4S Structural formula: CH2=CH—C(O)—NH—C(2CH3)—CH2—SO3H

Chemical Properties: 2-Acrylamide-2-methylpropanesulfonic acid is a vinyl monomer with a sulfonic acid group. It has good thermal stability, the decomposition temperature can reach up to 210 °C, and the decomposition temperature of its sodium salt homopolymer can reach 329 °C. In the aqueous solution, the hydrolysis rate is slow, and the sodium salt aqueous solution has excellent hydrolysis resistance under high pH conditions.

Under acidic conditions, the hydrolysis resistance of its copolymers is much higher than that of polyacrylamide. The monomer can be made into either a crystal or an aqueous solution of sodium salt.

Full name: 2-Acrylamide-2-methylpropanesulfonic acid.

English name: 1-acrylanmido-2-methylpropanesulfonic acid

1) Molecular weight and molecular formula: molecular weight & molecular structure m= C7H13NSO4

2) Properties: It is a strong acid, and its pH in aqueous solution depends on its concentration. Its sodium salt is neutral in water.

At 25, 100 grams of water can dissolve 150 grams of this product, and 100 grams of dimethylformamide (DMF) can dissolve more than 100 grams of this product. The maximum solubility of this product in 30% ethanol is 30%. The rest of the solvent is very soluble to it.

It is highly absorbent of water, and dried amps are stable at room temperature and do not self-polymerize, but it is easy to polymerize in aqueous solutions. It is hydrolyzed very slowly in aqueous solution, and the sodium salt of this product is not hydrolyzed within one month in aqueous solution of pH=9.

3) Uses: This homopolymer or acrylic acid copolymer low molecular weight polyelectrolyte is the best dispersant to prevent calcium phosphate, calcium carbonate, zinc salt, iron and slime in the current anti-scale decomposition agent for water treatment. As a slurry on textiles, it is added to synthetic fibers, and the moisture absorption of fabrics can be improved due to the introduction of sulfonic acid groups.

The homopolymer and copolymer of this product can improve the flow of oil in the well and increase production.

Production method: There are two kinds of production method: one-step method and two-step method. The one-step method is to react the raw materials acrylonitrile, isobutylene, and oleum together. The two-step method is to sulfonate isobutylene in the presence of a reaction solvent to obtain a sulfonation intermediate, and then react with acrylonitrile in the presence of sulfuric acid.

One-step method is more economical. Raw material consumption quota: isobutylene 300kg t, acrylonitrile 290kg t, oleum spicy 560kg t.
