Patent application number | Description | Published |
20120128567 | PROCESS FOR WORKUP OF LIQUID RESIDUES OF THE DIRECT SYNTHESIS OF ORGANOCHLOROSILANES - The invention provides a process for thermal cleavage of the high-boiling residues of the direct Müller-Rochow synthesis to give silanes with hydrogen chloride in a fluidized bed of silicon dioxide-containing, aluminum-free particles. | 05-24-2012 |
20120316356 | METHOD FOR HYDROSILYLATION USING A PLATINUM CATALYST - The selectivity of hydrosilylation of unsaturated organic compounds by Si—H functional organosilicon compounds is improved by use of a silyl polyphosphate ester in conjunction with a platinum hydrosilylation catalyst. | 12-13-2012 |
20120330045 | PROCESS FOR CONVERSION OF DISILANES - Highly alkyl-substituted disilanes generally considered as uncleavable, obtained as part of the residue of alkylchlorosilane synthesis, are converted into cleavable disilanes having fewer alkyl groups by reaction with hydrogen halide in the presence of an alumina catalyst. The resulting disilanes can be cleaved into commercially valuable monosilanes by conventional processes. | 12-27-2012 |
20140221677 | Hydrolysis Of Organochlorosilanes In Tube Bundle Reactor - A process for hydrolyzing organochlorosilanes involves reacting organochlorosilanes with water in a tube bundle reactor to form a polyorganosiloxane-containing crude hydrolyzate and hydrogen chloride. | 08-07-2014 |
20140369771 | CONVEYING OF FINE SOLIDS IN THE SYNTHESIS OF ALKYLCHLOROSILANES - Pneumatic conveying of fine solids in the direct synthesis of alkylchlorosilanes conveying gas containing at least 50% by volume of alkyl chloride. The conveying apparatus preferably contains a means for switching conveying gas in the pneumatic conveying of fine solids. | 12-18-2014 |
20150290558 | DISTILLATION OF SILANE MIXTURES IN THE PRESENCE OF A NITRILE OR AMINE - Distillation of silane mixtures in the presence of a nitrile, amine, or mixtures thereof, the nitrile and amine each having a boiling point of at least 120° C. at 1013 hPa, is effective to remove metal halide, organometal halides, and other contaminants. | 10-15-2015 |
20150291920 | CLEANING INDUSTRIAL PLANT COMPONENTS TO REMOVE METAL HALIDES - Cleaning industrial plant components to remove silane, metal halide, and organometallic halide contaminants and mixtures thereof, involves treating the plant components with a liquid nitrile or amine or mixture thereof or with a solution of a nitrile or amine or mixture thereof in an aprotic solvent. | 10-15-2015 |
20150361115 | METHOD FOR PRODUCING ALKYL CHLOROSILANES BY WAY OF REARRANGEMENT REACTIONS - Alkyl chlorosilanes from the manufacture of dialkyldichlorosilanes are rearranged in continuous fashion to dialkyldichlorosilane by a rearrangement reaction in a moving bed reactor employing a solid alumina catalyst containing aluminum chloride, spent catalyst being continuously removed from the reactor. | 12-17-2015 |
