TRICHLOROSILANE PRODUCTION |
| 摘要 |
A process that includes combining hydrogen chloride, metallurgical grade silicon and a third gas, e.g., tetrachlorosilane, in a reactor, under reaction conditions that include a temperature of 250-400 C. and a pressure of 2-33 barg, for a time sufficient to convert metallurgical grade silicon to an exit gas that includes trichlorosilane. |

1. A process comprising combining hydrogen chloride, metallurgical grade silicon and a third material (M3) selected from silicon tetrachloride, trichlorosilane, dichlorosilane, and hydrogen, in a reactor, under reaction conditions comprising a temperature of 250-400° C. and a pressure of 2-33 barg, for a time sufficient to convert metallurgical grade silicon to an exit gas comprising trichlorosilane. |
