标题:Synthesis of cyclic trithiocarbonates from epoxides
发明人：PARKER DANE KENTON
权利人:GOODYEAR TIRE & RUBBER
摘要:This invention provides a low cost technique for synthesizing cyclic trithiocarbonates by a simple one step process from epoxides that can be conducted under atmospheric pressure. This synthesis can be depicted as follows: n nwherein R represents a moiety selected from the group consisting of alkyl groups and aryl groups, wherein R′ represents a moiety selected from the group consisting of alkyl groups, aryl groups, and hydrogen atoms, and wherein R″ represents a moiety selected from the group consisting of alkyl groups, aryl groups, and hydrogen atoms, wherein the R moiety and the R′ moiety can be bonded together to form a cyclic structure, with the proviso that R″ represents a hydrogen atom if R′ represents an alkyl group or an aryl group. In this process carbon disulfide and a thiocyanate salt, such as potassium thiocyanate, are reacted with the epoxide in an ionic liquid, such as 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim] PF 6 ) in the presence of water to produce the cyclic trithiocarbonate.

权利人:VITO NV
摘要:Organic-inorganic hybrid materials using lignin as the organic phase for the synthesis of thin films are described. These hybrid materials are prepared through the known sol-gel method whereby a metal-oxide precursor and alkoxysilane functionalized lignin are used and subsequently processed to obtain coatings and thin films with a high content in lignin.

权利人:CHARPENTIER PAUL A; LI XINSHENG
摘要:A one step synthetic route of polymeric compositions of a polyolefin and inorganic network consisting of components selected from Si, Zr, Ti, is disclosed. The synthetic route combines parallel reactions of free radical polymerization to form polymer, and hydrolysis of either Si, or Zr, or Ti or both of them precursors. The network consisting of Si, Zr, Ti, is chemically bonded to or within the polymer matrix. The inorganic or organic molecules can then be polymerized under conditions effective to cause the polymerized inorganic or organic molecules into macromolecular networks. The compositions of the polymeric composites can be easily controlled by adjusting the reactant ratio and reaction rate or conditions such as temperature and pressure, wherein the inorganic compositions disperse in nanoscale within polymeric composites when their concentrations fall below moderate levels. A novel synthesis route for making polymer composites and/or polymer nanocomposites of a polyolefin and an inorganic network consisting of components selected from Si, Zr, Ti, is disclosed. The synthesis route comprises hydrolysis of either Si, or Zr, or Ti alkoxides or mixtures of these precursors within a polymer matrix in supercritical fluids.
