Abstract: The method of preparation of tetraphenylporphyrin (H2TPP) has been improved by using a mixed solvent based on the propionic acid and thionyl chloride as oxidizing agent instead of 2, 3-dichloro-5,6-dicyanobenzoqinone. The yield of the pure H2TPP achieved 38%. Six complexes of H2TPP with Cu, Co, Ni, Fe, In, and La were prepared respectively.

Key words: tetraphenylporphyrin, porphyrin metal complex, preparation
