| titleOfInvention | PROCESS FOR THE CONTINUOUS PREPARATION OF SULFONATES DERIVED FROM ALKYL LONG-CHAIN MOLECULES AND, MORE PARTICULARLY, FATTY ESTERS |
| abstract | The invention relates to a process for the continuous preparation of sulfonates derived from long chain molecules and more particularly of fatty esters. According to the invention, the starting product 5 is subjected to the action of a sulfonating agent 10, 2 is degassed, the sulfonation product thus obtained 6 and it is treated 3 with slightly aqueous methanol to obtain on the one hand an ester phase containing the unsulphonated starting product which is recycled 12 in the sulphonation step, and on the other hand a methanol phase which contains the desired sulphonic acids and which is subjected to evaporation 4 making it possible to separate from on the one hand methanol and on the other hand said sulphonic acids.
