| titleOfInvention | Process for producing hemin and protoporphyrin diester and protoporphyrin disodium salt |
| abstract | (57) [Summary] [Purpose] Hemin, hematin, which is useful as an intermediate of protoporphyrin disodium used as a liver drug, And a method for producing protoporphyrin diester, and a method for producing the protoporphyrin disodium. [Composition] A method of producing a protoporphyrin diester by reacting a heme iron concentrate with hydrogen chloride gas and ferrous salts in an organic solvent; treating a heme iron concentrate with oxalic acid, caustic alkali, ammonia, or pyridine Then, the heme present in the heme iron concentrate is converted to hematin, and the hematin is extracted and separated with an organic solvent; a method for producing hematin; heating the hematin with sodium chloride in acetic acid. Method for producing hemin chloride by treatment; method for producing protoporphyrin diester by reacting the hemin chloride with hydrogen chloride gas and ferrous salts in an organic solvent; action of methanol caustic in the organic solvent A method for producing protoporphyrin disodium, which comprises: |
