摘要： Processes for separating conjunct polymer from an organic phase are described. A mixture comprising an ionic liquid phase and the organic phase into the ionic phase and an organic phase comprising the conjunct polymer and at least one silyl or boryl compound. The organic phase is separated in a fractionation column into an overhead fraction comprising unreacted silane or borane compound and a bottoms fraction comprising the conjunct polymer and the silyl or boryl compound. The bottoms fraction is passed through an adsorption zone, and the silyl or boryl compound is recovered. Alternatively, the organic phase is passed through an adsorption zone first to remove the conjunct polymer and then a fractionation zone to separate the unreacted silane or borane compound from the silyl or boryl compound.

摘要： A method of forming chloro-substituted silanes from the reaction of an alkoxysilane with a chlorinating agent in the optional presence of a catalyst is provided. More specifically, chloro-substituted silanes, including but not limited to silicon tetrachloride, are formed by reacting a chlorinating agent, such as thionyl chloride, with an alkylalkoxysilane having the formula (R′O)4-xSiRx, where R and R′ are independently selected alkyl groups comprising one or more carbon atoms and x is 0, 1, 2, or 3. The catalyst may be dimethylformamide, (chloromethylene)dimethyliminium chloride, or triethylamine, among others. The chloro-substituted silane formed in the reaction along with several by-products has the formula (R′O)4-x-ySiRxCly; where x is 0, 1, 2, or 3 and y is 1, 2, 3, or 4. One of the by-products of the reaction is an alkyl chloride.

摘要： This method for manufacturing trichlorosilane, includes: reacting metallurgical grade silicon with silicon tetrachloride and hydrogen so as to obtain a reaction gas; condensing the reaction gas so as to obtain a condensate; and distilling the condensate using a distillation system including a first distillation column and a secondary distillation column so as to refine trichlorosilane. While maintaining the condensate in a high temperature state so that a concentration of aluminum chloride in the condensate becomes in a range of a saturation solubility or less, the condensate flows to the first distillation column. A liquid distilled in the first distillation column is distilled by the secondary distillation column so as to refine trichlorosilane. A liquid in which aluminum chloride is concentrated is extracted from a bottom portion of the first distillation column. The extracted liquid is concentrated and dried, and then aluminum chloride is exhausted.

摘要： Method and apparatus for producing molten purified crystalline silicon from low-grade siliceous fluorspar ore, sulfur trioxide gas, and a metallic iodide salt. Method involves: (1) initially reacting silicon dioxide-bearing fluorspar ore and sulfur trioxide gas in sulfuric acid to create silicon tetrafluoride gas and fluorogypsum; (2) reacting the product gas with a heated iodide salt to form a fluoride salt and silicon tetraiodide; (3) isolating silicon tetraiodide from impurities and purifying it by washing steps and distillation in a series of distillation columns; (4) heating the silicon tetraiodide to its decomposition temperature in a silicon crystal casting machine, producing pure molten silicon metal ready for crystallization; and pure iodine gas, extracted as liquid in a cold-wall chamber. The system is batch process-based, with continuous elements. The system operates largely at atmospheric pressure, requiring limited inert gas purges during batch changes.
