FIELD: petrochemical synthesis, organic chemistry, chemical technology.
SUBSTANCE: invention relates to synthesis of linear unsaturated dimmers of α-methylstyrene. Method involves the dimerization reaction of α-methylstyrene in the presence of anhydrous copper (II) sulfate as a catalyst taken in the amount 1-5 wt.-% at the reaction temperature 60-800C. Invention provides enhancing yield of the end product wherein α-isomer of α-methylstyrene prevails. Synthesized substances can be used as regulators of polymers molecular mass, solvents and a base for preparing synthetic oils.
EFFECT: improved method of synthesis.
