摘要:在温和的条件下,在b(c 6 F 5)3存在下,氢硅烷或氢硅酮可将硫醇或二硫化物转化为甲硅烷基硫醚.在这些条件下,与硫醇或二硫化物相比,发现醇的反应更快,而烷氧基硅烷的反应更慢.使用温和的基于氧气的亲核试剂可实现硫醇的释放(甲硅烷基脱保护).

标题:Synthesis of inorganic membranes on supports
发明人：RUDERMAN WARREN; FEHLNER JAMES R; ZHANG ZHENYU
权利人:INRAD
摘要:Inorganic membranes such as zeolite membranes or other molecular sieve membranes can be provided by using silicone polymer material as starting material. A thin film zeolite membrane or a thin film membrane formed of interlocking zeolite crystals can be provided. Water soluble or water insoluble silicones can be treated in a basic solution under conditions and with an appropriate structure directing template, suitable aluminum content and at a temperature that is appropriate for growing a desired inorganic crystal framework. The membranes can be formed across the perforation of a support, such as a steel screen.

摘要:The present technology provides compositions, methods, and processes to form polysiloxanes. In one aspect, the present technology provides a process for the ring opening polymerization of a cyclosiloxane comprising contacting a cyclosiloxane with a bicyclic guanidine compound. The guanidine-containing compounds useful in the ring opening reaction include a fused ring structure comprising a guanidine functional group as part of the fused ring.

标题 :Synthesis of zwitterionic siloxane polymers
发明人：FLORENCE ROBERT A; CAMPBELL JOHN R; WILLIAMS JR ROBERT E
权利人:GEN ELECTRIC
摘要:A method is provided for producing aminoalkyl-siloxane polymers of a high molecular weight by hydrolyzing a difunctional aminoalkyl-silane prior to incorporation into the siloxane polymer. The high molecular weight siloxane polymers obtained may be converted to zwitterionic siloxane rubbers with excellent engineering properties and integrity.
