    摘要: A process for the preparation of ether sulfonates or polyglycol ether sulfonates by reacting an organic alcoholic or phenolic compound or the corresponding alkoxylate in aqueous solution with vinyl sulfonate in the presence of from 0.1 to 3.0% by weight of an alkaline catalyst and, if required, additionally in the presence of a phase-transfer catalyst, and ether sulfonates or polyglycol ether sulfonates prepared by this process and of the general formulaR--O(C.sub.n H.sub.2n O).sub.z --CH.sub.2 CH.sub.2 SO.sub.3 Xwhere R is H or an aliphatic or aromatic hydrocarbon radical (which may contain nitrogen as a heteroatom) of 1 to 30 carbon atoms, n is from 2 to 30, z is from 0 to 300 and X is an alkali metal.
