PROCESS FOR PREPARING OXIMESILANE

摘要

PURPOSE: A process for preparing oximesilane is provided to stably process unstable organic chlorine, and reduce the preparation costs by reducing the amount of solvent and ammonia. CONSTITUTION: A process for preparing oximesilane represented by the formula(1) of R¬14-nSi(-O-N=CR2R3) comprises the steps of: slowly adding dropwise of 1 mole of silane compound represented by the formula(3) of R¬14-nSiXn into 3.0 to 3.3 mole of oxime compound represented by the formula(2) of R¬2R¬3C=N-OH and stirring them in the presence of organic solvent at 0 to 120 deg. C; and adding 1 to 6 mole of ammonia into the mixture in situ to prepare oximesilane and ammonium chloride, wherein n is an integer of 1 to 4; and R¬1, R¬2 and R¬3 are independently hydrogen, or C1-6 saturated or unsaturated hydrocarbon.
