    • 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.
    • 在适用于大规模生产这些硅烷的氰基烷基 - 烷氧基硅烷的制备方法中,在溶剂存在下氯烷基烷氧基硅烷与碱金属氰化物的反应在搅拌反应器中进行, 提供了用于装载这些原料的装置和用于碱金属氯化物副产物的出口,并且通过旁通阀连接到具有叠加的冷凝器的塔。 在反应器中的反应结束后,首先通过柱蒸馏除去溶剂,然后将氰基硅烷的主要部分蒸馏掉,然后在绕过柱子的同时蒸馏掉其余的氰基硅烷。 然后通过锁从反应器中除去碱金属氯化物。
