    • This invention relates to a process for preparing sulfonated lubricating agents for leather and tanned furs consisting of the steps of:(a) chlorinating natural or synthetic higher fatty acids or esters of higher fatty acids having chain lengths of from 8 to 24 carbon atoms containing olefinically unsaturated fractions, up to saturation of the double bonds;(b) sulfochlorinating the chlorinated product from step (a) with chlorine and SO.sub.2 at a temperature of from about 20.degree. to 90.degree. C., optionally under UV-radiation, for a time sufficient to obtain a compound having a chlorine content of from about 5 to 30 percent by weight and a content of SO.sub.2 Cl groups of from about 1 to 20 percent by weight, the ratio of chlorine atoms to SO.sub.2 Cl groups being from about 0.7:1 to 70:1; and(c) saponifying the product from step (b) to form a water-emulsifiable alkali metal, ammonium, or lower alkyl-ammonium salt of the product of step (b).
    • 本发明涉及一种制备用于皮革和鞣制皮毛的磺化润滑剂的方法,该方法包括以下步骤:(a)将具有包含烯属链的8至24个碳原子链长度的天然或合成的高级脂肪酸或高级脂肪酸的酯进行氯化 不饱和部分,直到双键饱和; (b)在约20-90℃的温度下,任选地在UV辐射下,用步骤(a)的氯代产物用氯和SO 2进行磺酸氯化足够长的时间,以获得氯含量为 约5至30重量%,SO 2 Cl基团含量为约1-20重量%,氯原子与SO 2 Cl基团的比例为约0.7:1至70:1; 和(c)将来自步骤(b)的产物皂化以形成步骤(b)的产物的水可乳化的碱金属,铵或低级烷基 - 铵盐。
