Abstract
A process of producing ketone condensation products which comprises condensing at a temperature of from 60.degree. to 300.degree.C. a ketone having 3-19 carbon atoms in the presence of, as a catalyst, at least one metal phosphate selected from titanium phosphate, zirconium phosphate, hafnium phosphate, and tin phosphate; dimeric condensation or trimeric condensation can be achieved depending upon the reaction conditions.
Claims4
A process of producing unsaturated ketone condensation products which comprises condensing at a temperature of from 60.degree. to 300.degree.C., a ketone of 3-19 carbon atoms having the following formula ##EQU5## wherein R.sub.1 is either alkyl, cycloalkyl, aryl, aralkyl, alkaryl or alkenyl, and R.sub.2 and R.sub.3, which may be the same or different are each hydrogen, alkyl, cycloalkyl, aryl, aralkyl, alkaryl or alkenyl,
- said process being carried out in the presence of a catalyst consisting of at least one metal phosphate selected from the group consisting of titanium phosphate, zirconium phosphate, hafnium phosphate, and tin phosphate.
