Paragraph 0082-0085; 0092-0094, (2021/11/05)
The invention provides a method for producing an epoxy compound by hydrogen peroxide using an organic compound having a carbon-carbon double bond as a raw material, wherein a by-product is suppressed from being generated and the epoxy compound is produced in a high yield. In particular, the invention provides a method for producing an epoxy compound involving oxidizing a carbon-carbon double bond in an organic compound with hydrogen peroxide in the presence of a catalyst, wherein the catalyst comprises a tungsten compound; a phosphoric acid, a phosphonic acid or salts thereof; and an onium salt having an alkyl sulfate ion represented by formula (I) as an anion: wherein R1 is a linear or branched aliphatic hydrocarbon group having 1 to 18 carbons, which may be substituted with 1 to 3 phenyl groups.
METHOD FOR PRODUCING ALICYCLIC DIEPOXY COMPOUND
-
Paragraph 0057, (2015/05/26)
The present invention provides a method for producing an alicyclic diepoxy compound at a higher yield by carrying out epoxidation of an alicyclic olefin compound at a higher reaction rate. The method is a method for producing an alicyclic diepoxy compound represented by formula (1) below by reacting an alicyclic olefin compound represented by formula (2) below with hydrogen peroxide in the coexistence of the alicyclic olefin compound represented by formula (2) below, a hydrogen peroxide solution, a powdered solid catalyst support and a powdered solid catalyst all together: wherein R1 to R12 are each hydrogen, halogen, an alkyl group optionally having halogen or an alkoxy group optionally having a substituent.
