FIELD: chemistry.
SUBSTANCE: invention relates to a method for catalytic production of homo- and co-oligomers of α-methylstyrene and isopentenes. The method is characterized by the fact that an amorphous mesoporous aluminosilicate ASM is used as a catalyst, the reaction is executed in chlorobenzene at a molar ratio of α-methyl styrene:isopentenes = 1:1.5 to 2, the amount of the catalyst of 5 to 20% wt. per the mixture of initial unsaturated compounds, at 20 to 65°C, atmospheric pressure, for 3 to 5 hours.
EFFECT: effective method for producing a mixture of homo- and co-oligomers of α-methylstyrene with isopentenes, making it possible to obtain target compounds with a good yield, under mild conditions.
