摘要： Methods are provided for producing isomerically enriched camphorsulfonates, and in particular a diastereomerically enriched glycidyl camphorsulfonate by bromide-casylate exchange between an alkyl casylate and the bromide analog of the desired casylate, followed by separation of a higher melting diastereomer by selective recrystallization. There is also shown the production of a desired casylate by reacting a racemic or enantiomerically enriched arenesulfonate with a quaternary casylate. Randomization and recycling of an isomerically enriched casylate is provided by reaction with an achiral bromide analog in the presence of a quaternary salt. Specially adapted apparatus for conducting the randomization reaction is provided. There is also shown a process for producing an alkyl casylate by the reaction of a metal casylate and a quaternary casylate with a trialkyl phosphite in the presence of a slight molar excess of sulfuric acid.

摘要： A method of purifying a crude glycidyl (meth)acrylate, by (1) subjecting a crude glycidyl (meth)acrylate containing epichlorohydrin and other chlorine compounds as impurities to a stripping treatment with a mixed gas containing oxygen gas in the presence of a quaternary ammonium salt, and then (2) distilling the treated product to obtain a purified glycidyl (meth)acrylate.
