标题 :Catalyst for organic synthesis use, and method for producing organic compound
发明人：KATO AYUMU; NAKAMURA SHINJI
权利人:ORGANO CORP
摘要:Provided are: a catalyst for organic synthesis use, which has a high catalytic activity, can be easily separated by solid/liquid separation from a reaction system, and enables highly efficient synthesis of an organic compound; and a method for producing an organic compound using the catalyst. This catalyst for organic synthesis use includes an anionic exchange resin that has a hydrohalic acid salt of a tertiary amino group as an ion exchange group. This method for producing an organic compound uses, as a catalyst, an anionic exchange resin that has a hydrohalic acid salt of a tertiary amino group as an ion exchange group.

摘要:Process for synthesizing and purifying polyol fatty acids polyesters or other nondigestible fats selected from the group of esterified linked alkoxylated polyols and esterified epoxide extended polyols, in which unreacted lower alkyl ester is recovered from a reaction mixture and recycled for use in the synthesis of the nondigestible fat. The process includes the steps of reacting an excess of lower alkyl ester with polyol to esterify hydroxyl groups thereof and form polyol fatty acid polyester, separating at least a portion of the unreacted lower alkyl ester from the polyol fatty acid polyester, and recycling the separated unreacted lower alkyl ester for further reaction with polyol or partially esterified polyol. The recycled lower alkyl ester is substantially free of lower alkyl ester degradation reaction products, such as carbonyls and free fatty acids.

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.

标题:Process for synthesis of allophanate compounds and compositions including the product thereof
发明人：TAZZIA CHARLES L
权利人:BASF CORP
摘要:The invention provides a process for preparing an allophanate-containing compound in the presence of a metal catalyst and a tertiary amine. In a preferred process, the tertiary amine compound also has a hydroxyl group. The hydroxyl group can react with the isocyanate functionality. Also disclosed is a process in which an allophanate-containing compound is prepared with copper acetate monohydrate as a catalyst. The allophanate-containing compound is used as a curing agent in coating compositions, particularly electrocoat coating compositions. The coating compositions are used to coat articles.
