| titleOfInvention | A kind of production method of alpha, beta-lonone epoxide |
| abstract | The invention discloses the production method of a kind of β ionoionone epoxide in production of flavor field; it is under nitrogen protection; control temperature 0-40 DEG C of reaction system, with two (3,5 two trifluoromethyl) diselenide for catalyst; in a solvent; with hydrogen peroxide as oxidant, oxidation of beta ionoionone, it is thus achieved that epoxidation product 4 [2; 2,6 trimethyl 7 bases in oxabicyclo [4.1.0] heptan 1] 3 butylene 2 ketone.This method energy highly selective synthesis 4 [2,2,6 trimethyl 7 base in oxabicyclo [4.1.0] heptan 1] 3 butylene 2 ketone；Used oxidant cleans, and economy is high, and after oxidant reduction, by-product is only water, to environment non-hazardous；This method does not use metallic catalyst, and the organic selenium catalyst used is to ecological friendly；Reaction is carried out in temperate condition, neutral environment, little to equipment corrosion, durable, and catalyst can recycle, thus is more suitable for commercial production. |
