Recovery of sulphonic acid esters from a hydrocarbon stream |
| abstract |
A method for hydrolysis of a sulphonic acid ester in a hydrocarbon substrate by aqueous extraction of the hydrocarbon substrate, comprising steps of contacting the hydrocarbon substrate with an aqueous phase containing an ammonia salt, thereby hydrolyzing the sulphonic acid ester to the corresponding sulphonic acid; and recovering the sulphonic acid by separating the aqueous phase from the hydrocarbon substrate. |
