Metal porphyrin complexes are the generic terms of compounds of porphyrin and metal ions, when two of maternal porphyrin pyrrole protons (N - H) is replaced by metal ions, it will form the metallic porphyrin complexes immediately. Metal porphyrin complexes is widely existing in nature, and also the organism, such as in the cytochrome, hemoglobin, chlorophyll, etc; In addition, some metal porphyrin is olefin epoxidation or hydrocarbon oxidation catalyst, and the aldehyde carbonyl catalyst, or functional materials with optical, electrical, magnetic and other properties. 2017.01.22-Tungsten Carbide Rod Price
