The Synthesis of Tetraphenyl-Porphyrin(TPP) Under Microwave Irradiation

Guiying Jiang

Abstract

The synthetic methods of meso-teraphenylporphyrin(TPP) under microwave irradiation in organic solvent were researched. The optimum reaction conditions are as follows: 1.8g p-nitrobentoic acid as the catalyst in 100?ml xylene, 0.02mol phenylformaldehyde, 0.02?mol pyrrole, 210W microwave power and 15?min microwave irradiation. The yield reachs 52.9%. The purity of the product for TPP was 96% for recrystallization by double Wave-UV valuing.
