Product Description

High Purity Tetrachlorosilane with CAS 10026-04-7

Product Overview

Silicon tetrachloride, also known as silicon chloride, is an important raw material for the synthesis of silicone polymer compounds and the production of high purity silicon. It is a colorless, transparent, low viscosity liquid at room temperature. It is flammable and suffocating. Chemical formula SiCl4. The relative molecular mass is 169.89. The relative density is 1.48. Melting point - 68.8 ° C. The boiling point is 57.57 ° C. The refractive index is 1.412. The gas density (g/l) was 7.59. The critical temperature is 233 °C. The critical pressure is 0.375 MPa. Soluble in benzene, carbon disulfide, ether, chloroform, petroleum ether, carbon tetrachloride, titanium tetrachloride, tin tetrachloride. Due to the strong polarity of the silicon-chloride bond of this product, it can react violently with the nucleophilic reagent and release hydrogen chloride gas. Reaction with ammonia to form silylamine; react with ethanol or phenol to form silicate; at high temperature (1000 ° C) silicon tetrachloride can be reduced by hydrogen to produce elemental silicon; with metal hydrides such as lithium hydride, sodium hydride, Reaction with a reducing agent such as lithium aluminum hydride and borohydride to form a silane; reacting with a Grignard reagent to form a tetrahydrocarbylsilane or a partially hydrocarbylsilane; reacting with oxygen at a high temperature, but is stable to oxygen at a low temperature of. This product is toxic! Corrosive skin, strong irritation to the eyes and mucous membranes
