FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing (E)-4-phenyl-3-buten-2-one (benzalacetone) 
which can be used as a taste and aroma additive in the food industry and perfumery. The method involves reaction of styrene and acetic anhydride in the presence of a mesoporous amorphous aluminium-silicon-zircon oxide catalyst in molar ratio styrene:acetic anhydride=1:2-8, at temperature of 80-130°C, weight content of catalyst of 10-50% (with respect to the mixture of styrene and acetic anhydride, taken in molar ratio of 1:1).
EFFECT: invention enables to obtain the end product using a simple and low-cost method.
