METHOD OF PRODUCING (E)-4-PHENYL-3-BUTEN-2-ONE Russian patent published in 2013 - IPC C07C49/217 C07C45/69 C07C45/65

Abstract RU 2482105 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing (E)-4-phenyl-3-buten-2-one (benzalacetone) (I) 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 mesoporous mesoporous aluminosilicate (molar ratio SiO₂/Al₂O₃=80) with molar ratio styrene:acetic anhydride=1:2-4, at temperature of 120-130°C and weight content of the catalyst of 10-50 wt % (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.
