| titleOfInvention | Ether sulfonates and their preparation |
| abstract | Ether sulfonates are produced by reacting a C10-C20 fatty alkyl C1-C6 lower alkyl ether or a fatty alkyl (polyoxyalkyl) lower alkyl ether corresponding to the following formula R-O-(CnH2nO)x-R1 (I) ps in which R is an oleyl, palmitoleyl, or linoleyl radical, or mixtures thereof, n is an integer of from 2 to 4, x is an integer of from 0 to 30, and R1 is a saturated C1-C6 lower alkyl radical, with sulfur trioxide, contacting the sulfonate with aqueous alkali metal hydroxide solution and heating the solution until the sultones formed have been hydrolyzed. |
