Process for the preparation of derivatives of polyethoxypropanesulfonates |
| abstract |
57 Alkoxypolyethoxypropane sulfonates of the general formulan in which R is alkyl or alkaryl, Y is 0 or S and x is 0 to 20 are prepared by a two-stage procedure in which the polyethoxylated alcohol or thiol RY(C 2 H 4 O) x H is reacted with allyl halide or tosylate in the presence of strong aqueous NaOH and some final product as phase transfer agent and the resulting allyl ether intermediate is sulfonated in situ with bisulfite. |
