    摘要： A process for preparing an alkoxysilane with an acidic chloride content of less than 10 ppm by weight, comprising:reacting a chlorosilane with an alcohol in a water-free and solvent-free phase to form a product mixture containing alkoxysilane and residual acidic chloride, with removal of resultant hydrogen chloride from the product mixture,then adding liquid or gaseous ammonia, in an amount corresponding to a stoichiometric excess, based on the content of acidic chloride, to form an ammonia-containing product mixture,treating the ammonia-containing product mixture at a temperature between 10 and 50.degree. C., wherein the ammonia and acidic chloride undergo neutralization, to form a crude product, and optionally, then separating off a salt formed in the course of neutralization, from the crude product, andrecovering the alkoxysilane by distilling the crude product.

    摘要： An apparatus and method for the sampling and quantitative, IR-spectroscopic determination of impurities in hygroscopic liquids. The apparatus includes a stainless steel tube having a straight bore, a first end, and a second end. A first flange attachment is located at the first end of the stainless steel tube, and a second flange attachment is located at the second end of the stainless steel tube. First and second calcium fluoride plates are also located at the first and second ends of the steel tube, respectively. The first and second plates are oriented parallel to each other and perpendicular to the axis of the stainless steel tube. First and second outer flanges hold respective of the first and second plates in place at the first and second ends of the tube, respectively, and the first and second outer flanges are mechanically fixed to the first and second flange attachments, respectively. At least one seal separates the first plate from the first flange attachment and the first outer flange. Similarly, at least one seal separates the second plate from the second flange attachment and the second outer flange. First and second three-way taps are coupled by a first stainless steel line. A second stainless steel line couples the first three-way tap to the stainless steel tube, and a third stainless steel line couples the second three-way tap to the stainless steel tube. The method includes the steps of purging the first line with nitrogen gas and purging a cell space defined by the tube at least five times.

    摘要： In a method of preparing cyanoalkyl-akoxysilanes, which is suitable for the production of these silanes on a large technical scale, the reaction of a chloroalkyl-alkoxysilane with an alkali metal cyanide in the presence of a solvent takes place in a stirring reactor which is provided with means for loading these starting materials and with an outlet opening for the alkali metal chloride by-product, and which is connected through a bypass valve to a column with a superimposed condenser. After the reaction in the reactor has ended, first the solvent is distilled out through the column and then the main part of the cyanosilane, and then the rest of the cyanosilane is distilled out while bypassing the column. The alkali metal chloride is then removed from the reactor through a lock.
