FIELD: industrial organic synthesis.
SUBSTANCE: process is accomplished by dimerization of styrene in presence of Y-type zeolite with molar ratio SiO2/Al203 = 6-7 in H-form and with ion exchange degree 94-97% undergone heat treatment and utilized in amount of 5-10 wt % based on styrene. Reaction is carried out at 80-120°C in pseudocumene solvent used in (1-2):1 proportion to styrene.
EFFECT: simplified process and increased yield of end product.
