| titleOfInvention | Continuous process for manufacturing gamma sultones |
| abstract | A continuous process for manufacturing gamma sultones, which are detergent intermediates used to produce superior detergent compounds is disclosed. Olefins are treated with at least an equimolar amount of gaseous SO 3 and the resulting "acid mix" of unsaturated sulfonic acids, gamma sultones, and delta sultones is dissolved in a low boiling organic solvent. The resulting solution is cooled and the gamma sultones are precipitated as fine crystals. The gamma sultone crystals are collected, the solvent is evaporated and recovered, and the remaining "acid mix" residue (unsaturated sulfonic acids and delta sultones) is neutralized and hydrolyzed to produce olefin sulfonates. |
