| Abstract: | The present invention relates to an improved process for the preparation of a catalyst useful for sweetening of LPG and light petroleum distillates. The process relates to the preparation of sufphonamides of various metal phthalocyanines suitable as catalysts and their use for liquid-liquid sweetening of pentanes, LSRN, cracked naphtha and regeneration of alkali in the mercaptan extraction from LPG, pentanes, LSRN and light thermally cracked naphtha. The sulphonamides of the metal phthalocyanines suitable as sweetening catalysts are prepared by first converting the suitable metal phthalocyanine to the corresponding metal phthalocyanine sulphonyl chloride (mono-, di-, tri-, tetrasulphonyl metal phthalocyanine or a mixture thereof) followed by reacting the metal phthalocyanine sulphonyl chlorides with different amines including ammonia to yield the metal phthalocyanine sulphonamides. |
