摘　　要：为解决传统釜式反应器进行硝化反应时放热量大、浪费严重、效率低的不足,提出了一种基于微通道反应器的硝化反应技术。以合成对硝基乙酰苯胺为研究对象,对不同反应温度、反应时间、反应混合比情况下的反应效果进行了分析。结果表明,在以微通道作为反应器的情况下,当反应温度25℃,反应时间为50s的情况下具有最佳的硝化反应效果。In order to solve the shortcomings of traditional kettle reactor in Nitration,such as large heat release,serious waste and low efficiency,a nitration technology based on microchannel reactor was proposed.Taking the synthesis of p-nitroacetanilide as the research object,the reaction effects under different reaction temperatures,reaction times,and reaction mixing ratios were analyzed.The results show that the best Nitration effect can be obtained when the reaction temperature is 25℃and the reaction time is 50 s with the microchannel as the reactor.
