Abstract

PURPOSE: A crude unsaturated ketone derived from a prenyl halide and a ketone is combined with a trace amount of alkali to effect the decomposition of aldol condensates, by-products, in high efficiency, whereby the ketone product is recovered as a starting material to prevent the reduction in the yield of the ojbective unsaturated ketone.
CONSTITUTION: The condensation reaction of a prenyl halide of formula I (X is Cl or Br) with a ketone of formula II [R, R' may form a ring together with CH2 COCH2, when they do not form a ring, they are H, 1W5C alkyl, when forming a ring, -R-R'- are alkylene of -(CR1R2)n-(R1, R2 are H, 1W5C alkyl; n is 1W3)] is conducted by the use of an alkaline condensing agent and the reaction mixture is treated to give a purified unsaturated ketone, wherein less than 0.2 equivalent amount, preferably 0.0003W0.1 equivalent amount, based on 1mol of the unsaturated ketone, of an oxide, hydroxide carbonate of alkali or alkaline earth metal or a quarternary ammonium hydroxide or its polymer, is added.
