Process for the preparation of a novel catalyst useful for sweetening of sour petroleum distillates

摘要

A process for the preparation of a supported catalyst comprising a Halogenated Phthalocyanine of cobalt, iron or manganese of formula 1which comprises: mixing a phthalocyanine of cobalt, iron or manganese with a halogenating agent in a stoichiometric ratio ranging between 1:1 to 1:20 optionally in an inert organic solvent, refluxing or heating and stirring for a time period ranging between 1-6 hrs, distilling the excess halogenating agent from the mixture, filtering and washing the residual mass by known method to obtain the desired halogenated phthalocyanine and impregnating a support material with the desired halogenated phthalocyanine.
