Abstract
An efficient and clean production method of a phenolic compound comprises the following steps: adding corresponding arylamine compound into a certain amount of acidic catalyst aqueous solution, heating for hydrolysis, cooling to room temperature, adding an extraction solvent to extract a generated phenolic compound, separating the extraction solvent from an extraction liquid to prepare a finished phenolic compound product, evaporating residual extraction solvent and partial water from the extracted acidic mother liquor, mixing a certain amount of polar protic solvent to precipitate inorganic ammonium salt in the mother liquor, dissolving salt formed by the arylamine compound which is not hydrolyzed and is incompletely hydrolyzed and the acidic catalyst and excessive acidic catalyst in the polar protic solvent, separating the inorganic ammonium salt precipitate, further distilling to remove the polar protic solvent, sleeving the salt of the arylamine compound which is not hydrolyzed and is incompletely hydrolyzed and the excessive acidic catalyst in the synthesis of the next batch, and continuing the hydrolysis reaction.
Description
The technical field is as follows: the invention belongs to the technical field of chemical raw material synthesis, and particularly designs an efficient and clean production method of a phenolic compound.
Secondly, background art: the phenolic compounds are important chemical raw materials, have wide application fields, are closely related to the production and the life of human beings, and can be applied to medicines, pesticides, veterinary drugs, materials, auxiliaries, dyes, pigments, coatings, adhesives, plastics, rubber, electronic chemicals and the like. There are a variety of methods for preparing such compounds, including: sulfonate alkali fusion method, amino compound acid hydrolysis method, amino diazotization hydrolysis method, hydrogen peroxide hydroxylation method, isopropyl compound oxidation hydrolysis method, halogenated hydrocarbon alkali hydrolysis method, hydroxylamine rephotography method and the like.
Due to localization or environmental protection, safety, technology, resources, and the like, with the development of science and technology and materials, the acidic hydrolysis of aromatic amines to convert the amino group of aromatic amines into hydroxyl group to prepare corresponding phenolic compounds gradually becomes some of the main industrial preparation methods of phenolic compounds, such as: p-methylphenol, m-methylphenol, 2-naphthol, 1-naphthol, m-hydroxybenzoic acid, p-hydroxybenzoic acid, 3, 5-dimethylphenol, p-phenylphenol, hydroquinone, resorcinol, 2, 4-dihydroxytoluene, 2-methylresorcinol, phloroglucinol, 1, 5-dihydroxynaphthalene, 3, 5-dihydroxybenzoic acid, 2, 5-dimethylphenol, 3, 4-dimethylphenol, 8-hydroxyquinoline, 4-hydroxydiphenylamine and the like.
The main reaction processes are exemplified as follows:

2. m-phenylenediamine is hydrolyzed in acid to prepare resorcinol:
3. preparing m-hydroxybenzoic acid from m-aminobenzoic acid:
4.2, 4-diaminotoluene acidic hydrolysis to prepare 2, 4-dihydroxytoluene:
5. 2, 6-diaminotoluene acidic hydrolysis to prepare 2, 6-dihydroxytoluene:
the common acids for hydrolyzing the arylamine compounds comprise sulfuric acid, ammonium bisulfate, hydrochloric acid, hydrobromic acid, phosphoric acid and the like, when the arylamine compounds are hydrolyzed by a conventional method to prepare corresponding phenolic compounds, the excessive amount of the acids is more when the sulfuric acid is used as a catalyst, the utilization rate of acid radicals is less than 50 percent, mother liquor after the phenolic compounds are extracted is generally introduced into ammonia gas to neutralize residual acidity, a byproduct ammonium sulfate is prepared after concentration, and raw materials and intermediates which are not hydrolyzed are difficult to recover and utilize; the ammonium bisulfate is used as a catalyst, the excessive acid is also large, the generated ammonium sulfate needs high temperature when being converted into the ammonium bisulfate, and the raw materials and intermediates remained by hydrolysis are damaged and are difficult to be continuously utilized; phosphoric acid is used as a catalyst, the phosphoric acid is used in a large excess amount, in the existing documents, after the phosphoric acid aqueous solution after hydrolysis is supplemented with consumed phosphoric acid, the phosphoric acid aqueous solution is continuously used for 5-6 times, so that the utilization rate of the catalyst and raw materials is improved, but finally, a large amount of acidic mixed mother liquor by-product cannot be treated, the raw materials and intermediates which are not hydrolyzed completely are difficult to recover and utilize, and a large amount of phosphoric acid has to be neutralized by ammonia to prepare ammonium phosphate by-product.
However, no matter how the arylamine compound is hydrolyzed, a certain amount of waste acid is generated, not only part of raw materials and intermediates are mixed, but also alkaline substances are required to be added for neutralization so as to treat the waste mother liquor, so that more waste salt impurities are generated, the environmental hazard is large, and the product yield is low.

(3) The technical effects are as follows: the invention relates to a high-efficiency and clean production method of phenolic compounds, which comprises the steps of adding corresponding arylamine compounds into a certain amount of acidic catalyst aqueous solution, heating for hydrolysis, cooling to room temperature, adding an extraction solvent to extract the generated phenolic compounds, separating the extraction solvent from an extraction liquid to prepare a finished phenolic compound product, evaporating residual extraction solvent and partial water from an extracted acidic mother solution, mixing a certain amount of polar protic solvent to precipitate inorganic ammonium salts in the mother solution, dissolving salts formed by the arylamine compounds and the acidic catalysts which are not hydrolyzed and are incompletely hydrolyzed and excessive acidic catalysts and the polar protic solvent into the polar protic solvent, separating the inorganic ammonium salts precipitate, further distilling to remove the polar protic solvent, and sleeving the salts of the arylamine compounds which are not hydrolyzed and incompletely hydrolyzed and the excessive acidic catalysts for the synthesis of the next batch, the hydrolysis reaction is continued. Thus, the product yield is improved, the use efficiency of the catalyst is improved, the environmental hazard is reduced, and the process method is efficient, clean and safe.
The concrete aspects are as follows:
1. the polar protic solvent is adopted as the precipitation solvent, so that the generated inorganic ammonium salt has low solubility in the polar protic solvent, and the polar protic solvent is added to be easily precipitated, so that the acidic catalyst in the hydrolysis mother liquor is conveniently recycled, the use efficiency of the catalyst is improved, the production cost is reduced, and the environmental hazard is reduced.
