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.

摘要:Provided is a method for the preparation of a metal lattice-doping catalyst in an amorphous molten state, and the process of catalyzing methane to make olefins, aromatics, and hydrogen using the catalyst under oxygen-free, continuous flowing conditions. Such a process has little coke deposition and realizes atom-economic conversion. Under the conditions encountered in a fixed bed reactor (i.e. reaction temperature: 750Ëœ1200° C.; reaction pressure: atmospheric pressure; the weight hourly space velocity of feed gas: 1000Ëœ30000 ml/g/h; and fixed bed), conversion of methane is 8-50%. The selectivity of olefins is 30Ëœ90%. And selectivity of aromatics is 10Ëœ70%. There is no coking. The reaction process has many advantages, including a long catalyst life (>100 hrs), high stability of redox and hydrothermal properties under high temperature, high selectivity towards target products, zero coke deposition, easy separation of products, good reproducibility, safe and reliable operation, etc., all of which are very desirable for industrial application.
