Compounds whose organic groups are bonded to silicon atoms via oxygen, sulfur, nitrogen, etc., are also commonly considered organosilicon compounds. Among these, polysiloxanes, with a silicon-oxygen bond (-Si-O-Si-) backbone, are the most numerous, most extensively studied, and most widely used type of organosilicon compound, accounting for over 90% of total usage. However, the production of organosilicon requires stirred reaction vessels.
[0003] However, in the current stirred reactors used for organosilicon production, the catalyst is delivered through the feeding port at the top of the reactor, which makes it difficult for the catalyst to be evenly distributed in the medium of the reactor. This reduces the consistency of the reaction and the reaction efficiency between the catalyst and the medium in the reactor. Utility Model Content
