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 |
