Process for producing sulfonate of unsaturated fatty acid ester |
| abstract |
A process for producing a sulfonate of an unsaturated fatty acid lower alkyl ester comprising the steps of:(i) sulfonating a mixture of (A) a lower alkyl ester of an unsaturated C<sub>8</sub> to C<sub>22</sub> fatty acid and (B) a lower alkyl ester of a saturated C<sub>8</sub> to C<sub>22</sub> fatty acid in a weight ratio of (A)/(B) = 90/10 to 5/95 with a sulfonating agent in such a manner that the amount of the unreacted component (A) in the total unreacted components in the mixture is at least 0.3% by weight; and(ii) neutralizing and hydrolyzing the sulfonated product.This process provides the desired sulfonate of unsaturated fatty acid ester having a pale tone color at a high conversion. When the sulfonated product is separated by using (a) a polyol (or polyhydric alcohol) having 2 to 8 carbon atoms, (b) an alkylene glycol in a liquid state at an ambient temperature, or (c) an olefin having 6 to 30 carbon atoms, the desired sulfonate can be separated at a high recovery efficiency and with good workability. |
