Study on Continuous Nitration Process of 6-Nitro-1,2,4-Acid Oxidatoid
6-Nitro-1,2,4-acid oxidatoid was synthesized from 1,2,4-acid oxidatoid by continuous process of dissolved in concentrat-ed sulfuric acid and then reacted with nitric acid.The effects of process conditions such as reaction temperature,reaction time,and reaction residence time on the reaction were investigated.The results showed that the optimum condition was achieved when n(oxy-gen):n(nitric acid):n(sulfuric acid)= 1 ∶ 1.06 ∶ 7.56,the reaction temperature was 0～5℃,and the residence time of the loop reactor was 180 minutes.
