ABSTRACT:
This invention relates to an improved liquid/liquid process for oxidizing mercaptans in a sour hydrocarbon fraction. The improvement is the addition of a quaternary ammonium compound to the alkali metal solution which contains a metal chelate such as a metal phthalocyanine. A preferred type of quaternary ammonium compound is a surfactant quaternary ammonium compound. A synergistic effect between the quaternary ammonium compound and the metal chelate is observed.
