Application Progress of Microchannel Reactor in Nitration Reaction of Aromatic Compounds

芳香化合物的硝化是常用的生产单元,采用传统釜式反应器进行硝化反应存在放热量大、选择性低、浪费资源、污染环境、存在安全隐患等问题。微通道反应器具有优良的传热、传质性能,可有效解决传统釜式反应器存在的问题,是一种安全、环保、高效的新型反应设备。综述了微通道反应器在芳香化合物硝化反应中的应用进展,包括以苯型芳香烃为底物的硝化反应及以非苯型芳香烃为底物的硝化反应。

Nitration of aromatic compounds is a common production unit of chemical engineering process,whereas,some problems exist in nitration reactions in the traditional tank reactor,such as excessive exotherm,low selectivity,waste of resources,environmental pollution,and potential safety risks.Microchannel reactor has excellent properties of heat and mass transfers,and can be adopted to effectively solve the problems existing in the traditional tank reactor,which is a new type of safe,environmental,and efficient reaction device.In this paper,we review the application of microchannel reactor in nitration reactions of aromatic compounds,including nitration reactions using benzenoid aromatic hydrocarbon as substrate and using non-benzenoid aromatic hydrocarbon as substrate.
