| titleOfInvention | Novel method for producing 2-acrylamido-2-methylpropanesulfonic acid |
| abstract | The present invention is a method for producing 2-acrylamido-2-methylpropanesulfonic acid, which comprises at least the following sequential steps: 1) acrylonitrile, at least one SO 3 source compound, and -80 to 30 ° C. Mixing the isobutylene and sulphonated mixture at a temperature between 2: 1 and a SO 3 : isobutylene molar ratio between 0.2: 1 and 2: 1 and an acrylonitrile: isobutylene mole between 3: 1 and 60: 1. By ratio, contacting and mixing at a temperature between -40 and 100 ° C., 3) solid-liquid separating the reaction mixture and isolating solid particles in the form of composition 1, 4) end of step 3) Mixing Composition 1 of Example 1 with aqueous solution A at a temperature between -20 and 70 ° C to produce 2-acrylamido-2-methylpropanesulfonic acid crystal suspension 1; 5) suspension Solid-liquid separation of 1 and isolation of crystals in the form of composition 2. |
