The present invention deals with a process for sweetening a sour hydrocarbon fraction containing mercaptans. The process involves contacting the hydrocarbon fraction with a catalytic composite in the presence of an oxidizing agent, ammonium hydroxide and a quaternary ammonium salt other than hydroxide. The instant process does not use any strong base nor any alkali hydroxides to sweeten the sour hydrocarbon fraction and thus obviates waste disposal problems.
