FIELD: chemistry.
SUBSTANCE: present invention pertains to the method of producing linear styrene dimers (cis- and trans-1.3-diphenylbut-1-enes) through oligomerisation of styrene in the presence of zeolite catalyst in a solvent. The method is characterised by that, the catalyst used is ZSM-12 type zeolite in H-form, in quantity of 5-20 wt %. The reaction is carried out in nonane with ratio styrene:nonane = 1:2-4 (vol.) and 80-110°C temperature.
EFFECT: use of this method simplifies the method of producing linear styrene dimers.
