METHOD OF PRODUCING (E)-4-PHENYL-3-BUTEN-2-ONE

摘要

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.8 ex, 1 tbl
