METHOD OF PRODUCING INDENE DIMERS Russian patent published in 2011 - IPC C07C13/28 C07C2/04 B01J29/40 C07C2/46 C07C2/12

Abstract RU 2415122 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing indene dimmers through catalytic dimerisation of indene, characterised by that the catalyst used is zeolite ZSM-12 in H-form in amount of 10-30 wt % and the reaction is carried out at 100-200°C in aliphatic hydrocarbons in ratio indene: solvent equal to 1:1-4 (vol).

EFFECT: method simplifies production of indene dimers.
