    摘要: 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.

    摘要: In the production of a gypsum-based porous body of high strength by foaming a gypsum-water mixture, the improvement which comprises including in said mixture about 0.1 to 1 part of a water-soluble aluminum compound per 100 parts by weight of gypsum, calcium oxide or calcium hydroxide in such a quantity that the final mixture has a pH-value in the range of about 10 to 13, a decomposition catalyst, and about 0.5 to 5 parts of hydrogen peroxide, expressed as a 35% solution, per 100 parts by weight of mixture, the ratio of solids to liquid being about 1 : 0.4 - 1.The preferred aluminum compound is aluminum nitrate. The preferred decomposition catalysts are manganese compounds such as manganates or permanganates, e.g. potassium permanganate.
