Research on Determination and Preparation of Diphenic Acid

Abstract:

The oxidation of phenanthrene, with peracetic acid and by means of reaction distillation, into 2,2’-diphenic acid, and determination of phenanthrene, phenanthrenequinone and diphenic acid in the oxidation reaction mixtures, with a HPLC, have been studied. For the determination of phenanthrene, phenanthrenequinone and diphenic acid, the experimental results showed that the concentrations of the three components and their corresponding peak area presented good linear relationship. And for the oxidation, main technical parameters optimized by orthogonal test. The optimum conditions were as follows: molar ratio of phenanthrene to acetic acid: 1.0:25.0; molar ratio of phenanthrene to H2O2: 1.0:8.0; dropping time of 30%H2O2: 9h; reaction time:18h；solvent: benzene; reaction temperature: about 90°C(boil).
