Procedure for valuing aliphatic, aromatic or cyclic olefinic derivatives, contaminated with sulfur, malodorous, or mixtures thereof, characterized in that it comprises the steps of putting in contact said olefinic derivative contaminated with sulfur, malodorous, or a mixture thereof, with 0, 1 to 5% by weight approximately of a lower peralkanoic acid, at a temperature between -10 ° C and 80 ° C; washing the olefinic derivative thus treated with water; and then recovering an olefin with reduced sulfur content, improved odor and stable on storage. |
