Alkali metal salts and alkaline earth metal salts of' acyloxybenzenesulfonate are prepared by sulfonating an aryl ester of an organic acid with gaseous sulfur trioxide to produce a sulfonation reaction mixture containing acyloxybenzenesulfonic acid, neutralizing the sulfonation reaction mixture with alkali metal hydroxide or alkaline earth metal hydroxide to produce an alkali metal salt or alkaline earth metal salt of an acyloxybenzenesulfonic acid and thereafter recovering from the reaction mixture the acyloxybenzenesulfonic acid salt product thus formed.
丙烯酰氧基苯磺酸的碱金属盐和碱土金属盐的制备方法是:将有机酸的芳基酯与气态三氧化硫磺化,生成含有丙烯酰氧基苯磺酸的磺化反应混合物,用碱金属氢氧化物或碱土金属氢氧化物中和磺化反应混合物,生成丙烯酰氧基苯磺酸的碱金属盐或碱土金属盐,然后从反应混合物中回收由此生成的丙烯酰氧基苯磺酸盐产物。
