METHOD FOR PREPARING 1,3-DIPHENYLBUT-2-ENE-1-ONE Russian patent published in 2005 - IPC

Abstract RU 2263657 C1

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to a method for preparing 1,3-diphenylbut-2-2ene-1-one (dypnone) from acetophenone in the presence of cation-exchange polymerizing sulfoacid resin in H⁺-form as a catalyst at temperature 80-160°C. The process can be carried out in the presence of nonpolar aliphatic hydrocarbon solvent. Acetophenone fraction isolating in the process for the combined preparing propylene oxide and styrene can be used as acetophenone. Method provides selectivity is 84-98.8% by dypnone in consumption of catalyst 3.0-3.4% of acetophenone mass.

EFFECT: improved preparing method.
