PHLORGLUCINOL DIHYDRATE - Reference Information
| use | used as analytical reagent used as pharmaceutical, biological reagent, dye, can also be used to synthesize 5,7-dihydroxyflavone used as biological reagent, dye, and used to test vanillin, lignin, determination of sugar aldehyde, pentose, etc. |
| Production method | 1.? In the presence of a catalyst, benzene is reacted with propylene, and the resulting mixture is rectified to obtain triisopropylbenzene. Then compressed air is introduced into triisopropylbenzene, and the autooxidation reaction is carried out at 60?~ 120 ℃ with azo-diradical initiator as catalyst, and the solution ph = 8~9 is controlled. The alcohol by-products produced by the reaction are oxidized with 2 to 6 times hydrogen peroxide under acidic conditions and converted into the required product 1,3, 5-triisopropylbenzene trihydroperoxide. The peroxide is decomposed into the target product phloroglucinol under the action of a high-activity acidic catalyst, and the reaction heat should be removed in time during the reaction. The main reaction formula of the process is: the obtained acidic phloroglucinol is neutralized with 40% sodium hydroxide, and after extraction separation, adsorption and recrystallization, high-purity phloroglucinol can be obtained. |
