Preparation method of 4,6 - diphenyl azo resorcinol and 4,6 - diaminoresorcinol (by machine translation)

The invention relates to a preparation method of 4,6 - diphenyl azo resorcinol and 4,6 - diaminoresorcinol, wherein the phenylamine diazonium liquid is obtained by diazo reaction of aniline as a raw material; and the aniline diazonium liquid, the liquid base and the resorcinol aqueous solution are pumped into the dynamic tubular reactor according to a certain proportion, a flow speed and a sequential pump to obtain 4,6 -diphenyl azo resorcinol; and a high-purity 4,6 - diaminoresorcinol is obtained through hydrogenation. 4,6 -diphenyl azo resorcinol prepared by the present aniline method contains a small amount 2, 4 of substituted isomers and three-substituted impurities, and the problem of subsequent hindrance polymerization is influenced by virtue of the method, the purity of the diphenyl azo resorcinol obtained by the method is high, and the obtained 4,6 - 4,6 -diaminoresorcinol is less in impurities.
