权利人:MOMENTIVE PERFORMANCE MAT INC
摘要:A process for the direct synthesis of alkenylhalosilane monomers. Forming a slurry of liquid and copper-activated silicon from fresh silicon, cyclone fines and/or fine dust from silicon grinding, ultrafines and/or spent contact mass from the Direct Synthesis of alkylhalosilanes and arylhalosilanes, in a thermally stable solvent. Reacting the silanes by agitating the slurry with at least one unsaturated aliphatic or cycloaliphatic organohalide of the formula R1X, and optionally an organohalosilane and/or hydrogen halide, in the presence of a polymerization inhibiting Lewis base additive, at a reaction time, temperature and pressure effective to produce alkenylhalosilanes having the formulae, R1SiHX2, R12SiHX, R13SiX, R1SiX3, and R12SiX2 or mixtures thereof.

标题 :Synthesis of polyol bis(allyl carbonate) utilizing reagent recovery and recycle
发明人：YOUNG ELGIN E
权利人:PPG INDUSTRIES INC
摘要:Disclosed is an improved method of forming polyol (allyl carbonate) monomers. In the disclosed method, the organic by-products as diallyl carbonate and unreacted reagents as allyl alcohol are separated from the brine and wash water derived aqueous phase and returned to the allyl carbonate synthesis reaction. The aqueous phase is further separated to recover allyl alcohol therefrom, which is returned to the allyl carbonate synthesis reactor as an azeotrope.

标题:Selective synthesis of 2-haloalkanethiols and episulfides therefrom
发明人：MUELLER WOLFGANG H; OSWALD ALEXIS A; KOZAK PETER J
权利人:EXXON RESEARCH ENGINEERING CO
摘要:Haloalkanethiols are synthesized through the free radical liquid phase reaction of halogenated olefins with an excess of hydrogen sulfide. High product yields to the desired haloalkanethiol products are secured when a 3 to 20 fold molar excess of hydrogen sulfide to halogenated olefin is used. Desirably, the synthesis is carried out to a conversion level not exceeding 90%. The haloalkanethiol products can be subsequently dehydrohalogenated to the corresponding episulfide products by reacting the haloalkanethiol product with a substantially equal molar amount of anhydrous ammonia.
