Problems solved by technology

[0003] In the existing synthesis method of ethylene glycol phenyl ether compounds, phenol and oxirane are used for synthesis, but this type of method will use dangerous epoxy compounds, and the catalyst used is expensive and corrosive, and the obtained The product is low yield and the product is complex
Anil K.Kinage and others have improved the synthetic method of diol phenyl ethers. They use phenol and cyclocarbonate to react in KL molecular sieves, but this method needs to be carried out at a higher temperature, and the catalyst is difficult to prepare, and This reaction will produce 2-(2-phenoxyethoxy)ethanol by-products

Abstract

The invention relates to a synthetic method of diol phenylate compounds, which is characterized in that raw material comprises aromatic compounds, diol, metal salt catalysts, alkali, reaction promoting ligand and reaction solvent; the raw material is added in a reactor and stirred for 1 to 72 hours under the temperature ranging from 50 to 220 DEG C; the raw material is extracted through organic solvent and concentrated through a rotary evaporator, and then the diol phenylate compounds are obtained through column passing; a chemical reaction equation is shown in a patent specification; the synthetic method achieves high efficiency; in addition, metal salt is adopted as the catalysts, so that non-corrosiveness can be achieved, and the synthetic method is convenient to prepare and use.

Description

technical field [0001] The invention belongs to the technical field of organic compound synthesis, and in particular relates to a synthesis method of diol phenyl ether compounds. Background technique [0002] Glycol phenyl ether series are widely used in automobile and automobile repair coatings, electrophoretic coatings, industrial baking varnishes and ships because of their non-toxicity, good miscibility, moderate volatilization rate, excellent coalescence and coupling ability, and low surface tension. Containers, wood coatings. It is a good solvent for polymers such as oils / natural resins / cellulose fibers / alkyd resins. Widely used as solvents and specialty chemicals for personal care products such as soaps, detergents, perfumes, cosmetics, toilet products and the pharmaceutical industry. [0003] In the existing synthesis method of ethylene glycol phenyl ether compounds, phenol and oxirane are used for synthesis, but this type of method will use dangerous epoxy compound...
