Abstract

Procedure for obtaining maleic anhydride; in liquid form by cooling the reaction gases from the catalytic oxidation of benzol to a temperature that oscillates between the condensation temperature of maleic anhydride and the dew point of steam water characterized by the fact that the gases cross the condensation chamber ascending.
