Definition
ChEBI: 2-Methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid is an organosulfonic acid.
Preparation
2-Acrylamido-2-methylpropanesulfonic acid(AMPS) can be synthesized by one step and two steps. 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 sulfonated 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 560kg/t.
Solubility in organics
