| Abstract: | Aims] This paper aims to study the optimum conditions for synthesis of 2,6-dichlro-4-aminophenol.Methods] 2,6-Dichloro-4-aminophenol was synthesized by hydrogenation of 2,6-dichloro-4-nitrophenol. The synthetic process and purification was further optimized. Results] Under the optimal conditions, the yield of 2,6-dichloro-4-aminophenol was more than 93% with purity of 99.5%. Conclusions] A method was optimized for synthesis and purification of 2,6-dichloro-4-aminophenol with high yield and simple separation process, which was suitable for industrial production. |
