CHEMICAL AND PHYSICAL PROPERTIES

Physical Description Vinyltrichlorosilane appears as a colorless to pale yellow fuming liquid with a pungent odor. Vapor and liquid may cause burns. More dense than water. Vapors are heavier than air.
Color/Form Fuming liquid
Odor Sharp, choking; like hydrochloric acid
Boiling Point 195.1 °F at 760 mmHg (USCG, 1999)
Melting Point -139 °F (USCG, 1999)
Flash Point 70 °F (NFPA, 2010)
Solubility Soluble in most organic solvents
Density 1.26 at 68 °F (USCG, 1999) - Denser than water; will sink
Vapor Density 5.61 (Air = 1)
Vapor Pressure 65.9 [mmHg]
Autoignition Temperature 505 °F (USCG, 1999)
Decomposition The silanes decomp at elevated temp to liberate hydrogen and deposit a high purity silicon, which leads to some of the principal uses of silanes. /Silanes/
Corrosivity Corrosive
Heat of Combustion -4,300 Btu/lb = -2,400 cal/g = -100x10-5 J/kg
Heat of Vaporization 88 Btu/lb = 49 cal/g = 2.0X10+5 J/kg
Surface Tension 28 dynes/cm = 0.028 N/m at 20 °C
Polymerization Polymerizes easily.
Refractive Index Index of refraction = 1.4295 at 20 °C/D
Kovats Retention Index 682.6 685
Other Experimental Properties Reacts violently with water, moist air, or steam to produce toxic and corrosive fumes
Chemical Classes Toxic Gases & Vapors -> Chlorosilanes
