Usage

Chemical Properties

Colorless clear liquid

Uses

Intermediate for silicones.

General Description

A colorless liquid with a pungent odor. Flash point 100°F. Corrosive to metals and tissue.

Reactivity Profile

PROPYL TRICHLOROSILANE reacts violently with water, steam, moist air, alcohols, acetone, and light metals with generation of heat and flammable (H2) and corrosive (HCl) gases.

Hazard

Flammable, moderate fire risk. Strong irri- tant.

Health Hazard

TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Bromoacetates and chloroacetates are extremely irritating/lachrymators. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.

Flammability and Explosibility

Flammable

Safety Profile

Confirmed carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Poison by intraperitoneal route. Moderately toxic by ingestion. Human systemic effects: agranulocytosis, hepatitis, jaundice. Human teratogenic effects by ingestion:developmental abnormalities of the endocrine system and changes in newborn viability. Human and experimental teratogenic and reproductive effects. Human mutation data reported. When heated to decomposition it emits very toxic fumes of SOx, and NOx. See also MERCAPTANS.

The hydrosilylation of propylene

The reactions of separate and competitive hydrosilylation of propylene with HSiCl3, MeSiHCl2, Me2SiHCl, and MePh2SiH in the presence of the Speier catalyst (SC) with different additives and a catalyst obtained from SC and propylene were studied. A mutual influence of the hydrosilanes in the competitive reactions was found. The influence of various additives to SC on the process was considered.

Method for preparing propyl trichlorosilane by using tail gas propylene in chloropropyl chlorosilane production process

The invention relates to a method for preparing propyl trichlorosilane by using tail gas propylene in a chloropropyl chlorosilane production process, and belongs to the technical field of fine chemical engineering. According to the method, by-product tail gas propylene generated in the production process of chloropropyl chlorosilane is used as a raw material and is subjected to an addition reaction with trichlorosilane under stirring, and distillation is performed to obtain a propyltrichlorosilane product. As a silane intermediate, propyl trichlorosilane can be used as a cross-linking agent, a coupling agent, a building waterproofing agent, a powder treating agent and many other material industries of RTV silicone rubber after hydrolysis, alcoholysis and acylation. The method has the advantages of simple equipment process and byproduct raw materials, not only creates huge economic benefits, but also solves the problems of safety, environmental protection and occupational health of tail gas propylene in the production process of chloropropyl chlorosilane, and is suitable for industrial production.

PREPARATION OF ORGANOHALOSILANES

A process for preparing organohalosilanes comprising combining hydrogen, a halosilane having the formula HaSiX4-a (I), and an organohalide having the formula RX (II), wherein R is C1-C10 alkyl or C4-C10 cycloalkyl, each X is independently halo, and the subscript a is 0, 1, or 2, in the presence of a sufficient amount of a catalyst effective in enabling the replacement of one or more of the halo groups of the halosilane with the R group from the organohalide, at a temperature from 200 to 800 °C, to form an organohalosilane and a hydrogen halide, wherein the volumetric ratio of hydrogen to halosilane is from 1 :3 to 1 :0.001 and the volumetric ratio of hydrogen to organohalide is from 1 : 1 to 1 :0.001, and wherein the catalyst is optionally treated with the hydrogen or the halosilane prior to the combining.
