[Synthesis of 2,3,4-trihydroxyacetophenone hydrazones and study on their spectral properties].

2,3,4-Trihydroxyacetophenone was synthesized with pyrogallol. Benzoylhydrazone and p-hydroxybenzoylhydrazone were synthesized using the reaction of ethyl benzoate and methyl p-hydroxybenzoate with hydrazine hydrate. Three novel 2,3,4-trihydroxyacetophenone hydrazones were synthesized using the reaction of 2,3,4-trihydroxyacetophenone with benzoylhydrazone, p-hydroxybenzoylhydrazone and phenylhydrazine. IR, UV and the fluorescence spectrum of 2,3,4-trihydroxyacetophenone hydrazones were studied.
