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 .
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).
