METHOD OF PRODUCING DICYCLOPENTENE (TRICYCLO-[5.2.1.0]DECENE-3) Russian patent published in 2012 - IPC C07C13/47 C07C13/54 C07C13/547 C07C5/03 C07C5/05 B01J23/40 B81B1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing dicyclopentene (tricyclo-[5.2.1.0^2.6]decene-3), involving hydrogenation of dicyclopentadiene in a solution with hydrogen in liquid phase using fine catalysts of the platinum group at atmospheric pressure and moderate temperature of (30-80°C), followed by separation of the end product. The method is characterised by that hydrogenation is carried out in a toluene solution in the presence of an additive - functionally substituted aromatic compounds which are capable of being adsorbed on the surface of the catalyst, such as p-oxydiphenylamine, hydroquinone, β-naphthylamine, p-phenylenediamine, 2,6-di-tert-butyl-4-methylphenol, in amount of 1-5 wt % in terms of the catalyst used, and separation of the desired dicyclopentene is carried out by distilling toluene at low or atmospheric pressure.

EFFECT: use of the present method enables to obtain dicyclopenene of high purity.
