摘要： Compositions and a method of delivering a humectant to a surface such as skin by forming a reaction product of the humectant with an organosilicon compound. The reaction product is applied to the skin surface and contacted with moisture which causes the reaction product to undergo hydrolysis on the skin surface. This releases free humectant onto the skin surface and the silanol functional organosilicon compound formed as a result of the hydrolysis can be utilized on the skin surface as a durable water repellent and softening ingredient for the skin.

摘要： This invention relates to a method of separating close-boiling chlorosilanes from mixtures by employing the technique of liquid extraction with sulfolane and a hydrocarbon compound as co-solvents. The hydrocarbon compound employed is substantially immiscible in sulfolane and is present in sufficient amounts so that two liquid phases are formed, one being suloflane-rich and the other being hydrocarbon-rich. The mixture of chlorosilanes is intimately mixed with the two solvents and allowed to partition between the two phases. The preferred liquid extraction procedure is where the sulfolane and hydrocarbon solvent are in a countercurrent relationship within an extraction tower. Experimentally determined selectivity coefficients show that mixtures of (1) dimethyldichlorosilane and methyltrichlorosilane, (2) phenylmethyldichlorosilane and phenyltrichlorosilane, and (3) trimethylchlorosilane and tetrachlorosilane can be successfully separated by the techniques of this invention.
摘要翻译：本发明涉及通过采用液体萃取技术与环丁砜和烃化合物作为共溶剂分离近沸点氯硅烷的方法。使用的烃化合物在环丁砜中基本上是不混溶的，并且以足够的量存在，从而形成两个液相，一个是富含氟烷烃，另一个是富烃的。氯硅烷的混合物与两种溶剂紧密混合并允许在两相之间分配。优选的液体提取方法是环丁砜和烃溶剂在萃取塔内呈逆流关系。实验确定的选择性系数表明，通过本发明的技术可以成功地分离（1）二甲基二氯硅烷和甲基三氯硅烷，（2）苯基甲基二氯硅烷和苯基三氯硅烷和（3）三甲基氯硅烷和四氯硅烷的混合物。

摘要： An improved method for the separation of close-boiling chlorosilanes is described. The method consists of the extractive distillation of the close-boiling chlorosilanes using sulfolane as the extractive solvent and thereafter separating the higher-boiling chlorosilane and sulfolane by distilling the higher-boiling chlorosilane from the higher-boiling chlorosilane and sulfolane mixture to which is added a hydrocarbon solvent. Preferred hydrocarbon solvents include normal-heptane, normal-nonane, and 2,2,4-trimethylpentane. The sulfolane obtained from the higher-boiling chlorosilane and sulfolane mixture is suitable for recycling to the extractive distillation process as the sulfolane contains only limited amounts of dissolved chlorosilane.
