    • 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.
    • 本发明涉及使用连续方法制备有机二烷基烷氧基硅烷,所述方法包括在逆流反应器(例如板式塔或填充塔)中使链烷醇与ω-卤代烷基二烷基卤代硅烷连续接触。 反应在上述逆流反应器中在存在或不存在非反应性溶剂的情况下进行,同时清除所形成的盐酸。 由此形成的ω-卤代烷基二烷基烷氧基硅烷特别适合用作通过在碱金属多硫化物上的硫化反应制备具有通式(I)的硫的有机硅化合物的原料。
