| Abstract: | Introduces the pilot research of 2-aerylamido-2-methylpropanesulfonic acid （AMPS） production by one- step reaction t＇rom aerylonitrile, oleum and isobutylene. The process includes three units, synthesis, purification and solutions recovery. The mole ratio of acrylontfile, oleum and isobutylene is 7：1：1. The temperature of adding acid is 10 ℃, reacting for 3 hours; the temperature of adding isnbutylene is 40 ℃, and reacting for 2.5 hours. The yield of raw product is not less than 90%, the yield of purification is not less than 65%, and the mass fraction of AMPS after purification is greater than 99%. |
