Trichloro (phenyl) silane is a chemical compound from the group of silanes .

Extraction and presentation

Trichloro (phenyl) silane can be obtained by the Grignard reaction of silicon tetrachloride and phenyl magnesium chloride or by the reaction of benzene with trichlorosilane .

${\displaystyle \mathrm {ClMgC_{6}H_{5}+SiCl_{4}\longrightarrow Si(C_{6}H_{5})Cl_{3}+\ MgCl_{2}} }$

properties

Trichloro (phenyl) silane is a slightly volatile, colorless liquid with a pungent odor that decomposes in water to form hydrogen chloride. It decomposes when heated, which can produce hydrogen chloride , carbon dioxide , carbon monoxide and silicon dioxide . Your aqueous solution reacts strongly acidic.

use

Trichloro (phenyl) silane is used in the production of silicones , water repellants and adhesion promoters, etc.

safety instructions

The vapors of trichloro (phenyl) silane can form an explosive mixture with air ( flash point 86 ° C, ignition temperature 544 ° C).
