Abstract: A process for the treatment of a gasoline comprising diolefins, olefins and sulphur-containing compounds including mercaptans: a) demercaptanization by addition of at least a portion of the mercaptans onto the olefins by bringing the gasoline into contact with at least one first catalyst; b) treatment of the gasoline obtained from a) with hydrogen in a distillation column comprising at least one reaction zone including at least one second catalyst. The operating conditions and the second catalyst of b) are selected such that in the distillation column, separation of the gasoline obtained from a) into a light gasoline fraction and a heavy gasoline fraction is carried out simultaneously with a reaction for thioetherification and selective hydrogenation of the diolefins of a gasoline fraction obtained from a) by contact with the second catalyst.
