Production method
1,2, 4-phloroglucinol triacetate was prepared from p-benzoquinone and acetic anhydride, and then acted with hydrochloricacid to obtain the product. 1.1, Preparation of 2, 4-phenyltriacetate The dried p-benzoquinone was added to the mixture ofacetic anhydride and concentrated sulfuric acid in fractions at a reaction temperature of 40-50℃ for 1-3h. Add cold water tothe reactants, filter the precipitates, wash in cold water, recrystallize with alcohol, to obtain 1,2, 4-phenyltritriacetate. Melting
point 96.5-97℃. 2.1, Preparation of 2, 4-phenylgallol 5% hydrochloric acid was stirred with 1,2, 4-phenylgallol triacetate,heated to 90℃, hydrolyzed for 20min, and cooled. Neutralize with sodium carbonate and strain. The filtrate is extracted withether, and the ether extract is heated and steamed to obtain 1,2, 4-phenyltriester.
Use
Intermediate for organic synthesis, absorbent for gas analysis.
