CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Dodecyltrichlorosilane is a colorless to yellow liquid with a pungent odor. It will burn though it may take some effort to ignite. It is decomposed by moisture or water to hydrochloric acid with evolution of heat. It is corrosive to metals and tissue. |
|---|---|
| Color/Form | Colorless to yellow liquid |
| Odor | SHARP ODOR, LIKE HYDROCHLORIC ACID; PUNGENT |
| Boiling Point | greater than 300 °F at 760 mmHg (USCG, 1999) |
| Flash Point | greater than 150 °F (USCG, 1999) |
| Density | 1.03 at 68 °F (USCG, 1999) - Denser than water; will sink |
| Stability/Shelf Life | Readily hydrolyzed by moisture with production of hydrochloric acid. |
| 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 |
| Refractive Index | Index of refraction = 1.4581 at 20 °C/D |
| Other Experimental Properties | Readily hydrolyzed with liberation of hydrogen chloride |
| Chemical Classes | Toxic Gases & Vapors -> Chlorosilanes |
