Article Preview

Methods of separating mixed isomers of nitrochlorobenzene (NCB) were reviewed and analyzed in this paper, A new integrated technology including multiple side-draw distillation and continuous crystallization was raised for refining of high-purity p-nitrochlorobenzene(p-NCB) and o-nitrochlorobenzene(o-NCB) from the NCB mixture. Eventually, over 99% purity of p-NCB and o-NCB can be obtained, and the comprehensive yield is higher than 90%. Compared with the traditional process, the new technology has obvious advantages due to its simple process, high separation efficiency, and low energy consumption.
