<p>To produce an unsaturated carbonyl compound, a carbonyl compound is contained with an aluminum oxycarbonate catalyst, the water formed by the reaction being removed as it is formed. Thus, for example, trimethylnonenone can be produced from methyl isobutyl ketone, mesityl oxide from acetone, cyclohexylidene cyclohexanone from cyclohexanone, and phenyl betamethylstyryl ketone from acetophenone.</p> |
