    • The invention relates to a process for the production of sulphonic acid ester group-containing polyhydroxyl compounds having an average hydroxyl functionality of from 1.5 to 4, comprising reacting(a) paraffin sulphochlorides which are obtained by sulphochlorination of paraffins containing from 10 to 18 carbon atoms or of industrial mixtures of these paraffins, with unreacted paraffins and/or with chloroparaffins, having saponifiable chlorine content, based on the total weight of component (a), of from 5 to 15% with(b) an alcohol which is at least trihydric and which contains primary and/or secondary hydroxyl groups within the molecular weight range of from 92 to 250 or with mixtures of polyhydric alcohols having a molecular weight in the range of from 62 to 250 with an average hydroxyl functionality of from 2.5 to 5in the presence of hydrogen chloride acceptors while maintaining an equivalent ratio of hydroxyl groups to sulphochloride groups of at least 2:1 with the optional removal of sulphochloride group-free paraffin and/or chloroparaffin and excess alcohol from the reaction mixture after the reaction.
    • 本发明涉及一种具有平均羟基官能度为1.5至4的含磺酸酯基的多羟基化合物的制备方法,包括使(a)通过使含有10至18个碳原子的链烷烃的亚氯化得到的链烷烃氯化物 或这些链烷烃的工业混合物与未反应的烷烃和/或与氯代烷烃的有机物混合物,其组分(a)的可皂化氯含量为5至15%,(b)至少三元醇 并且其在92至250的分子量范围内含有伯和/或仲羟基,或者在分子量范围为62-250的多元醇与平均羟基官能度为2.5至5的混合物中 氯化氢受体的存在,同时保持至少2:1的羟基与硫酰氯基团的当量比,并且可选地除去 的不含亚磺酰基的无石蜡和/或氯代石蜡和过量的醇从反应混合物中反应。
