  • Separation Of Chlorosilanes
    Publication number: 20090026062
    Abstract: Crude chlorosilane streams containing lower-boiling chlorosilanes and higher-boiling chlorosilanes are separated by contacting them with a distillation aid. The lower-boiling chlorosilanes are separated from the crude chlorosilane stream, and then the distillation aid and the higher-boiling chlorosilanes are separated from one another. The distillation aid is a mono-cyano-substituted organic compound, a nitro-substituted organic compound, a mono-cyano-substituted organosilicon compound, a nitro-substituted organosilicon compound, or a mixture thereof. These distillation aids increase the relative volatility of crude chlorosilane streams such as methyltrichlorosilane and dimethyldichlorosilane resulting in improved separation at lower capital and/or fixed costs.
