The utility model relates to the field of efficient production of vinyl dimethylethoxysilane, in particular to a reaction kettle device for vinyl dimethylethoxysilane.

Background

Dimethyldiethoxysilane is an important raw material for synthesizing vinyldimethylethylsilane. Vinyl dimethyl ethyl silane can be used for synthesizing organic silicon intermediates and high molecular compounds, and is one of important raw materials for preparing silicon rubber. The reaction is accelerated by a constant-speed mechanical stirring rod in a reaction kettle, so that the problems of nonuniform stirring, low production efficiency, excessive resource consumption and the like are easily caused. In the reaction process of dimethyl diethyl silane and liquid metal sodium, the sodium condensation reaction time is 12 hours. The method is characterized in that the material is completely converted by sodium, after the reaction is finished, the reaction kettle needs to be purged before the material is fed again for reaction, and the process does not need to be stirred. Therefore, after the reaction is finished, the traditional mode of manually adjusting the mechanical stirrer is not timely enough, and the resource consumption is easily caused at low efficiency. Aiming at the problem, the utility model provides the numerical control magnetic stirring device for the dimethyl diethoxy silane reaction kettle, and the numerical control magnetic stirring device can automatically adjust the speed of the magnetic stirring rod according to the weight change of the sodium metal, so that the reaction efficiency is greatly improved, and the resource consumption is reduced.
