The present invention pertains to a process for the cross-ketonization (Piria reaction) between an aryl carboxylic acid and an aliphatic carboxylic acid using a metal-based compound and a slight or a moderate excess of aryl carboxylic acid. A good selectivity, up to 99 mol %, can be achieved. The aryl aliphatic ketone can be used for the preparation of surfactants and other downstream products.
