METHOD OF PRODUCING EPOXIDE OF DICYCLOPENTENE (EPOXIDE OF TRICYCLO-[5,2,1,0]DECENE-3,9-OXATETRACYCLO-[5,3,1,0,0]-UNDECANE) Russian patent published in 2013 - IPC C07D301/19 C07D303/06 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing epoxide of dicyclopentene (epoxide of tricyclo-[5,2,1,0^2.6]decene-3, 9-oxatetracyclo-[5,3,1,0^2.6,0^8.10]-undecane). The disclosed method involves hydrogenation of dicyclopentadiene in toluene solution with hydrogen at atmospheric pressure and moderate temperature (30-80°C) using finely dispersed platinum group catalysts and subsequent hydroperoxide oxidation of the obtained high-purity dicyclopentene in the presence of molybdenum-containing catalysts, at temperature of 80-110°C. Hydrogenation is carried out in the presence of an additive of functionally substituted aromatic compounds selected from a group comprising p-oxydiphenylamine, hydroquinone, β-naphthylamine, p-phenylenediamine and 2,6-ditert-butyl-4-methylphenyl, in amount of 1-5 wt % with respect to the catalyst used, and the dicyclopentene solution undergoes hydroperoxide oxidation directly in toluene without further separation of the dicyclopentene from hydrogenation products.

EFFECT: simple technique of producing the end compound and high output.
