75-94-5 Usage
Chemical Properties
Colorless or pale-yellow liquid. Readily hydrolyzed with
liberation of hydrogen chloride; polymerizes easily;
soluble in most organic solvents; reacts with
alcohol.
Uses
Different sources of media describe the Uses of 75-94-5 differently. You can refer to the following data:
1. Intermediate for silicones, coupling agent in
adhesives and bonds.
2. A study reports the possible use of this silane for treating Pluronic F127, chitosan for better attachment and proliferation of endothelial cells on biomaterials. Trichlorovinylsilane may be used to prepare epoxy terminated carbosiloxane.
General Description
A colorless to pale yellow fuming liquid with a pungent odor. Flash point 16°F. Vapor and liquid may cause burns. More dense than water. Vapors are heavier than air.
Reactivity Profile
Chlorosilanes, such as Trichlorovinylsilane, are compounds in which silicon is bonded to from one to four chlorine atoms with other bonds to hydrogen and/or alkyl groups. Chlorosilanes react with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous H2. They can serve as chlorination agents. Chlorosilanes react vigorously with both organic and inorganic acids and with bases to generate toxic or flammable gases.
Health Hazard
Inhalation causes irritation of mucous membranes. Vapor irritates eyes. Contact with liquid causes severe burns of eyes and skin. Ingestion causes burns of mouth and stomach.
Safety Profile
Moderately toxic by
ingestion, inhalation, and sktn contact. A
corrosive irritant to skin, eyes, and mucous
membranes. A very dangerous fire hazard
when exposed to heat or flame. Reacts
violently with water, moist air, or steam to
produce toxic and corrosive fumes. When
heated to decomposition it emits toxic
fumes of Cl-. See also CHLOROSILANES.
Purification Methods
Fractionally distil it at atmospheric pressure. It is water sensitive and is stored in the dark and it is likely to polymerise. [Müller & Schnurrbusch Chem Ber 91 1805 1958, Munkelt & Müller Chem Ber 92 1012 1959, Polarography: Abrahamson & Reynolds Anal Chem 24 1827 1952, Beilstein 4 IV 4258.]
Check Digit Verification of cas no
The CAS Registry Mumber 75-94-5 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 5 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 75-94:
(4*7)+(3*5)+(2*9)+(1*4)=65
65 % 10 = 5
So 75-94-5 is a valid CAS Registry Number.

Hydrosilylation process for gaseous unsaturated hydrocarbons
-
Page/Page column 5, (2010/02/16)
Organosilicon compounds are prepared by the addition reaction of a gaseous unsaturated hydrocarbon with a silane or siloxane containing at least one silicon-bonded hydrogen atom in the presence of a hydrosilylation catalyst in a liquid reaction medium. In this process the unsaturated hydrocarbon and optionally the silane or siloxane is dispersed into the liquid reaction medium by a jet eductor (also known as a venturi pump) device and the resultant gas-in-liquid dispersion is introduced into a bubble reactor.
A novel catalyst containing a platinum complex in polyethylene glycol medium supported on silica gel for vapor-phase hydrosilylation of acetylene with trichlorosilane or trimethoxysilane

, p. 1634 - 1635 (2007/10/03)
Hydrosilylation of acetylene with trichlorosilane or trimethoxysilane was carried out using a vapor-phase flow reactor with use of tetraammineplatinum(II) chloride in polyethylene glycol medium supported on silica gel as a catalyst, which is an active and thermally stable supported liquid-phase catalyst prepared readily from easily available materials, tetraammineplatinum(II) chloride, polyethylene glycol and silica gel.
Transition Metal Complexes of Troeger's Base and their Catalytic Activity for the Hydrosilylation of Alkynes
Goldberg, Yuri,Alper, Howard
, p. 369 - 372 (2007/10/02)
Rhodium(III) and iridium(III) complexes of Troeger's base (TB), of structural type TB*2MCl3 (M=Rh, Ir), were prepared by treatment of TB with MCl3.The rhodium complex readily catalyzed the hydrosilylation of alkynes with high regio- and stereoselectively observed in some cases.
