Description
Trichloropropylsilane is a colorless liquid with a pungent odor, known for its corrosive properties towards metals and tissue. It is characterized by a flash point of 100°F and is primarily used as an intermediate in the production of silicones.
Uses
Used in Chemical Industry:
Trichloropropylsilane is used as an intermediate for the synthesis of various silicone products due to its reactive nature and ability to form stable siloxane bonds.
Used in Silicone Production:
Trichloropropylsilane is utilized as a key component in the manufacturing process of silicones, which are widely used in numerous applications such as lubricants, sealants, adhesives, and elastomers, among others. Its role in silicone production is crucial for the development of these versatile materials.
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.
Check Digit Verification of cas no
The CAS Registry Mumber 141-57-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,4 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 141-57:
(5*1)+(4*4)+(3*1)+(2*5)+(1*7)=41
41 % 10 = 1
So 141-57-1 is a valid CAS Registry Number.

, p. 1992 - 1995 (1998)
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.

-
Paragraph 0021-0031, (2021/07/10)
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.

Page/Page column 17, (2011/12/14)
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.
