The manufacturing of Dichloromethyl Trichloro Silane requires a complex synthetic route, which involves the reaction of several chemicals. The process is carried out under controlled conditions to ensure high yield and purity of the final product. In this article, we will discuss the manufacturing process of Dichloromethyl Trichloro Silane and its applications in various industries.

The Manufacturing Process

The manufacturing process of Dichloromethyl Trichloro Silane involves the reaction of chloromethyl methyl ether (CMME) with silicon tetrachloride (SiCl4) in the presence of a catalyst. The reaction takes place at a temperature of 0-10°C and is carried out in a reactor vessel. The reaction is highly exothermic and requires careful control of temperature and pressure.

The first step in the process is the preparation of CMME. This is done by reacting methanol with hydrochloric acid and formaldehyde. The reaction takes place in the presence of a catalyst and produces CMME as the main product. The CMME is then purified by distillation to remove impurities.

In the next step, the purified CMME is reacted with SiCl4 in the presence of a catalyst. The catalyst used in the reaction is typically a Lewis acid, such as aluminum chloride (AlCl3) or ferric chloride (FeCl3). The catalyst enhances the reaction rate and increases the yield of the product. The reaction takes place at a temperature of 0-10°C and under atmospheric pressure. The reaction is highly exothermic, and the temperature needs to be controlled to avoid a runaway reaction.

The reaction between CMME and SiCl4 produces Dichloromethyl Trichloro Silane as the main product. The reaction also produces hydrochloric acid as a byproduct, which needs to be neutralized to prevent corrosion of the equipment. The product is then purified by distillation to remove any impurities and obtain a pure product.
