Problems solved by technology

However, this method requires a large excess of epichlorohydrin, and requires the use of a large amount of organic solvents. There are many side reactions, it is not easy to purify, and the post-treatment is complicated. The yield is generally 85-88%.
In addition, there are reports in the literature that the ionic liquid method is used to synthesize phenyl glycidyl ether, and the yield can reach 96.8%. However, the ionic liquid used in this method is more complicated to synthesize and expensive. In the process of practical application, the repeated use effect is not good.

Abstract

The invention relates to a synthesis method of phenyl glycidyl ether, and is characterized in that phenyl glycidyl ether is generated with phenol and chloropropylene oxide as raw materials and under the action of a catalyst, wherein the reaction is carried out in a micro-reactor. The method can greatly shorten the reaction time, avoids a lot of side reactions, and can synthesize phenyl glycidyl ether with high efficiency and high yield of more than 98%.

Description

technical field [0001] The invention relates to a synthesis method of phenyl glycidyl ether, which belongs to the technical field of organic chemical industry. Background technique [0002] The chemical name of phenyl glycidyl ether is 1,2-epoxy-3-phenoxypropane; 2,3-epoxypropylphenyl ether, the structural formula is shown in the attachment figure 1 Phenyl glycidyl ether is an important organic chemical intermediate, which can be widely used in coating industry, rubber industry and synthetic resin industry. In recent years, the research on the application of phenyl glycidyl ether is very active, mainly involving the synthesis of copolymers, the synthesis of homopolymers, resin modification, organic synthesis and other fields. [0003] The traditional synthesis method of phenyl glycidyl ether is obtained by reacting phenol and epichlorohydrin in the presence of a phase transfer catalyst. The method is characterized by simple and easy-to-obtain raw materials and simple ope...
