METHOD OF PREPARING ORGANO DIALKYLALKOXYSILANE |
摘要 |
The invention relates to the preparation of organodialkylalkoxysilane using a continuous method consisting in bringing an alkanol into continuous contact with an omega-haloalkyl dialkylhalosilane in a countercurrent reactor, such as a plate column or a packed column. The reaction is performed in the aforementioned countercurrent reactor in the presence or absence of a non-reactive solvent with scavenging of the hydrochloric acid formed. The omega-haloalkyl dialkylalkoxysilane thus formed is particularly suitable for use as a starting material for the preparation of organosilicon compounds containing sulphur having general formula (I) by means of sulphidisation reaction on an alkaline metal polysulphide.
