Process for the single-stage production of higher aliphatic ketones

摘要

A process for the single-stage production in the liquid or gaseous phase, of higher aliphatic ketones starting from ketones of lower molecular weight, characterized in that the starting ketones are reacted with carbon monoxide in the presence of a catalyst in the form of cooper supported on a metal oxide. The catalyst is prepared by depositing on the metal oxide the product obtained from hydrolyzing a cuprammonium solution, then calcining the solid system obtained in air and reducing the calcined product by means of hydrogen.
