The main raw material for industrial preparation of ethyl silicate is silicon tetrachloride, and silicon tetrachloride is produced by the reaction of chlorine with ferrosilicon. The process is relatively simple, namely heating the ferrosilicon to above 200 ℃, then pump into chlorine gas to generate silicon tetrachloride, and then get the finished product through refined distillation. The reaction equation is as follows: Si (ferrosilicon Si) + 2Cl2-(200 ℃) → SiCl4. The reaction equation of synthesis of ethyl silicate through the reaction between tetrachloride with ethanol and ethyl reaction is as follows: SiCl4 + 4C2H5OH → Si (OC2H5) 4 + 4HCl. If this reaction applies anhydrous ethanol, the product is ethyl silicate; if this reaction applies water-containing industrial ethanol and in the presence of acidic or alkaline catalyst, the resulting product is the mixture of ethyl silicate and poly ethyl silicate. This is due to the presence of water in the ethanol which can cause the hydrolysis and polymerization of ethyl silicate, the reaction is as follows: The industrial synthesis of ethyl silicate is actually the mixture of ethyl silicate and poly ethyl silicate. The polymerization degree (n) of poly-ethyl silicate is not high and in general n = 3-5, whose structural formula is as follows: The larger the value of n, the more complex molecular form and the higher the SiO2 content is as well as the greater its cohesion has and less stability it has. The production process of industrial production of ethyl silicate is shown in the above figure. Ethyl silicate can also be made from the esterification reaction of SiCl4 with C2H5OH at room temperature and room pressure, and then subjected to distillation according to the difference of the boiling points of components in the reaction product in order to remove the hydrogen chloride gas in the feed solution and distill the excess amount of ethanol. Finally after cooling, discoloration and filtration, we can obtain the ethyl silicate products. The above information is edited by the Chemicalbook of Dai Xiongfeng.
