Abstract

The invention provides a measuring method of porphyrin and metal porphyrin content. Firstly, the invention adopts thin-layer chromatography to detect sample purity, adopts a spectroscopic method for quantitative determination, adopts a spectrophotometer to respectively measure the absorbance value of tetraphenylporphyrin, tetraphenyl cobalt porphyrin, tetraphenyl iron porphyrin and tetraphenyl manganese porphyrin at the maximum wavelength adsorption position and utilizes measuring data to calculate porphyrin compound content in the sample. The invention has stable and accurate measuring result, favourable repeatability, few needed devices, simple operation and strong practicality, is especially suitable for synthesizing tetraphenylporphyrin and metal complex thereof and is suitable for quantitative determination of catalyst content when biomimetic catalysis cyclohexane produces cyclohexanol and cyclohexanone by taking tetraphenyl metal porphyrin as catalyst. The invention can provide convenient, quick, accurate, stable and practical analysis means for measuring content of porphyrin and metal porphyrin thereof and the content in biomimetic catalysis researching process, and is especially suitable for quickly analysis and tracking measurement of tetraphenyl metal porphyrin content.

Description

Technical field: [0001] The present invention relates to a method for measuring the content of porphyrin and metal porphyrin, in particular to a spectrophotometric method for measuring tetraphenylporphyrin (TPP), tetraphenylporphyrin cobalt (TPPCo), tetraphenylporphyrin Synthesis of ferrophyrin (TPPFe) and tetraphenylporphyrin manganese (TPPMn) and their quantitative determination during biomimetic catalysis research. Background technique: [0002] Porphyrin compounds are the skeletons that constitute a series of important physiologically active substances such as chlorophyll, hemoglobin, myoglobin, vitamin B12, cytochrome, and catalase. They are widely present in animals and plants and are active substances that play important physiological roles. center. Porphyrins are derivatives of porphine. There are many derivatives due to different substituent groups. Among them, tetraphenylporphyrin is the most basic structure type. When the two protons on the nitrogen are replaced ...
