    Abstract: Disclosed herein is a catalytic process for the synthesis of organohalosilane monomers from tetraorganodihalodisilanes and other compounds that are not cleaved during the conventional hydrochlorination of Direct Process Residue. The process is characterized by the use of a catalyst containing (1) one or more heterocyclic amines and/or one or more heterocyclic ammonium halides, and (2) one or more quaternary Group 15 onium compounds.

    Abstract: Dissolved silanes, silicones and silicates from solvents used in the slurry phase Direct Synthesis of alkoxysilanes are removed by adding a carboxylic acid such as formic acid to generate filterable precipitates and reusable solvent. The solvents are thereby remediated and made suitable for reuse in Direct Synthesis processes. Foaming is reduced with the remediated solvent and silicon conversion rates are higher. The precipitates are easily filtered and retain negligible quantities of solvent.

    Abstract: Discloses herein is a catalytic process for producing organohalosilane monomers from a high-boiling residue resulting from the Direct Reaction of an organohalide with silicon. The high-boiling residue contains more conventionally cleavable compounds than conventionally uncleavable compounds. The process includes heating the residue in the presence of a catalyst comprising (1) one or more heterocyclic amines and/or one or more heterocyclic ammonium halides, and (2) one or more quaternary Group 15 onium compounds.

    Abstract: A process is provided for separating a mixture of alkoxysilanes and alkanol, e.g., the crude product effluent of the Direct Reaction of silicon metal with alkanol, which comprises: a) introducing a mixture of alkoxysilane(s) and alkanol to a separation unit possessing a separation membrane having a first surface and an opposing second surface; b) contacting the mixture of alkoxysilane(s) and alkanol with the first surface of the separation membrane whereby one or more components of the mixture selectively absorb into the first surface and permeate therethrough to the second surface under the influence of a concentration gradient across the membrane thereby separating the mixture into an alkanol-enriched permeate fraction and an alkanol-deficient retentate fraction or an alkoxysilane-enriched permeate fraction and an alkoxysilane-deficient retentate fraction; and, c) recovering the permeate fraction.
