摘要： The instant invention is a catalyzed process for the redistribution of linear, chloride or hydroxy end-terminated polyorganosiloxanes or cyclic polyorganosiloxanes. Effective catalysts for the described process are alumina, silica-alumina, activated carbon, zeolite, and acid clay. The catalyzed redistribution process can be incorporated as an element of a three-stage process. The three-stage process allows control of the yield of cyclic polyorganosiloxanes.

摘要： What is described is a process for the treatment of organosilanes to reduce the content of more highly functional silanes. The process comprises (A) contacting a mixture, the mixture comprising a major portion of the organosilane and a minor portion of the more highly functional silanes, with organosiloxanes, and a sufficient amount of a catalyst effective in promoting the reaction between the more highly functional silanes and the organosiloxane to form more highly halogenated polyfunctional siloxanes; and (B) isolating the organosilane from the polyfunctional siloxanes and the organosiloxanes by conventional means such as distillation.

摘要： Endblocked methylpolysiloxane fluids, such as trimethylsiloxane-endblocked polydimethylsiloxanes, are made more resistant to thermally induced siloxane rearrangement by incorporating therein certain amounts of titanium-, zirconium-, or hafnium-containing compounds. Incorporation of these compounds may be accomplished either by mixing organosiloxy derivatives of Ti, Zr, or Hf with the fluid or by mixing certain organic derivatives of Ti, Zr, or Hf with the fluid and heating the mixture to decompose the added organic derivative. Furthermore, incorporation may be accomplished either by mixing the correct amount of the Ti, Zr, or Hf compound with the fluid or by mixing an excessive amount of the Ti, Zr, or Hf compound with the fluid to form a thermal-stability additive which may be diluted with additional fluid to achieve the correct amount of Ti, Zr, or Hf compound. Further improvements in the thermal stability of the fluid may be obtained by mixing with the titanium-, zirconium-, or hafnium-containing fluid a small amount of an organosilicon hydride compound. The thermally stabilized fluids are particularly useful as heat-transfer fluids in non-oxidative, anhydrous environments.

摘要： A process for separating methyltrichlorosilane from dimethyldichlorosilane in a mixture. The process comprises contacting a mixture comprising methyltrichlorosilane and dimethyldichlorosilane with activated carbon, where the methyltrichlorosilane is selectively adsorbed by the activated carbon. The process allows for the recovery of a dimethyldichlorosilane fraction reduced in methyltrichlorosilane concentration. The methyltrichlorosilane can be recovered by desorption from the activated carbon. The present process is especially useful for removing low levels of methyltrichlorosilane present as a contaminate in dimethyldichlorosilane.
