| titleOfInvention |
Process for the continuous preparation of sulfonates derived from molecules having long alkyl chains and, more particularly, sulfonates derived from fatty esters |
| abstract |
The starting material is subjected to the action of a sulfonating agent; the sulfonation product so obtained is degassed (2) and treated with slightly aqueous methanol in order to obtain, on the one hand, an ester phase containing the unsulfonated starting material which is returned to the sulfonation stage and, on the other hand, a methanol phase which contains the desired sulfonic acids and which is subjected to evaporation permitting the separation of the methanol from the said sulfonic acids. |
