FIELD: industrial organic synthesis.
SUBSTANCE: invention provides process for producing linear α-methylstyrene dimers useful as polymer molecular mass regulator, varnish solvents, dielectric liquids, and base for production of synthetic lubricating oils. Process is accomplished through dimerization of α-methylstyrene in presence of 0.5-4% of BETA-type zeolite in H form at 20-40°C for 2 to 8 h.
EFFECT: increased selectivity and improved technology.
