A novel multicomponent oxidation catalyst that can be effectively used in, for example, an epoxidation reaction of olefins, etc., being inexpensive and high in versatility and that exhibits high catalytic activity; and a process for producing an epoxy compound through hydrogen peroxide oxidation of an olefin with the use of the multicomponent oxidation catalyst. There is provided a multicomponent oxidation catalyst comprising a tungsten compound, a quaternary ammonium salt, any of phosphoric acids and/or boric acids and a hydrogen sulfate salt. Further, there is provided a process for producing an epoxy compound, characterized in that an olefin is oxidized with hydrogen peroxide in the presence of the above multicomponent oxidation catalyst. The epoxy compound obtained by this process is useful as an intermediate of agricultural chemicals, medicines or the like, a raw material of various polymers, etc.

Multicomponent oxidation catalyst and process for producing epoxy compound therewith

An object of the present invention is to provide a novel monomer compound having a lactone structure which gives polymers having more excellent feature as resist material, etc. The present invention relates to a compound represented by the following formula [1]: wherein Rand Rare an alkyl group; Rand Rare each independently hydrogen atom or an alkyl group; Ris hydrogen atom, acryloyl group or methacryloyl group; and X is a methylene group which may have an alkyl group or an ethylene group which may have an alkyl group. The present invention provides a compound having a lactone structure which gives a polymer having more excellent feature particularly as a resist material and also provides a hydroxy lactone being useful as a material, etc. therefor.
