Process for the preparation of methallyl sulfonic acid and its salts |
| abstract |
A process for the preparation of methallyl sulfonic acid and its salt which process comprises the reaction of isobutylene with a complex of sulfur trioxide to form methallyl sulfonic acid and, if desired, neutralization of the formed acid with an alkaline compound to obtain its salt. The sulfur trioxide complex is prepared by a reaction of sulfur trioxide with a mono-alkyl substituted amide of an aliphatic carboxylic acid, which has a tertiary carbon atom bonded directly to the nitrogen atom thereof. |
