METHOD OF PRODUCING LINEAR STYRENE DIMERS Russian patent published in 2009 - IPC C07C2/12 C07C15/18 C07C15/52 B01J29/40

Abstract RU 2349568 C1

FIELD: chemistry.

SUBSTANCE: present invention pertains to the method of producing linear styrene dimers (cis- and trans-1.3-diphenylbut-1enes) through oligomerisation of styrene in the presence of zeolite catalyst. The method is characterised by that, the catalyst used in ZSM-12 type zeolite in H-form, in quantity of 10-20 wt %. The reaction is carried out at 95-110°C temperature.

EFFECT: use of this method makes easier the production of unsaturated linear styrene dimers.
