[0006] Tetraaryl porphine TRPPH 2 The metallation process of tetraaryl porphyrin TRPPH is a reversible process, and metal salt needs to be greatly excessive when preparing tetraaryl porphyrin TRPPM; In addition, tetraaryl porphyrin TRPPH 2 and the solubility properties of tetraaryl metalloporphyrin TRPPM ​​are not good, and the solubility of product tetraaryl metalloporphyrin TRPPM ​​is better than that of reactant tetraaryl porphyrin TRPPH 2 worse
The above-mentioned characteristics in the synthesis of tetraaryl metalloporphyrins lead to the difficulty of product purification and the treatment of a large amount of solvents in the production of industrial large-scale metalloporphyrins, which increases production costs.

Abstract

The invention discloses a continuous production process of tetraaryl metal porphyrin. The process is as follows: firstly, adding a solvent into a multi-phase reaction separation synchronous reactor, wherein the reactor comprises a stirring reaction tower with a reflux device, and at least two constant-temperature settling towers communicated with the bottom of the stirring reaction tower, and the stirring reaction tower comprises a gas-phase region and a reaction region; during reaction, filling the solvent in the reaction region and the constant-temperature settling towers, adding the reaction material tetraaryl porphyrin and a metal salt into the stirring reaction tower for stirring when a temperature is increased to reach a reflux temperature of the solvent or reacting under the condition of ventilating air, directly settling the tetraaryl metal porphyrin generated by the reaction under gravity action to enter the constant-temperature settling towers until the constant-temperature settling tower is filled up with the tetraaryl metal porphyrin, switching the stirring reaction tower to communicate with the other constant-temperature settling tower filled with the solvent and carrying out the process alternatively to realize continuous production. The continuous production process disclosed by the invention can continuously produce high-purity tetraaryl metal porphin with high yield and low cost.

Description
