Production Method of AMPS 2-Acrylamido-2-methylpropanesulfonicacid:

Chemical synthesis

Chemical synthesis is one of the main methods to produce 2-acrylamide-2-methylpropanesulfonic acid. The method mainly includes the steps of synthesizing acrylamide, sulfonation reaction and neutralization reaction. Specifically, acrylamide is first reacted with dimethyl sulfate to obtain N-methylacrylamide, and then N-methylacrylamide is sulfonated with fuming sulfuric acid to obtain 2-acrylamide-2-methylpropanesulfonic acid. Finally, the acidic substance was removed by neutralization reaction, and the high-purity 2-acrylamide-2-methylpropanesulfonic acid product was obtained.

The advantages of chemical synthesis are a mature production process, large yield, low cost, and suitable for large-scale production. However, the raw materials used in the chemical synthesis process, such as fuming sulfuric acid, have a specific corrosive and toxic effect on the environment and human health. Therefore, paying attention to environmental protection and safety issues in the production process is necessary.

Bioenzymatic method

The Bioenzyme method is a new method for producing 2-acrylamide-2-methylpropanesulfonic acid developed recently. The method uses microorganisms or enzyme catalysts to convert acrylamide and sulfate into 2-acrylamide-2-methylpropanesulfonic acid. Compared with chemical synthesis, the enzymatic method has the advantages of mild conditions, high selectivity and environmental protection.

The specific steps of the biological enzyme method include:

• Mixing raw materials such as acrylamide and sulfate.

• Adding microorganisms or enzyme catalysts.

• Reacting under appropriate temperature and humidity conditions.

After the reaction, high-purity 2-acrylamide-2-methylpropanesulfonic acid products were obtained using separation and purification.

The advantage of the biological enzyme method is that using biocatalysts instead of chemical catalysts reduces the use and emission of harmful substances. At the same time, the biological enzyme method reacts under low temperature and humidity conditions, is environmentally friendly, has high selectivity, and can obtain products of high purity. However, the production cost of the biological enzyme method is high, and it needs to be further reduced to be widely used.
