The results showed that the key toxic pollutants were dinaphane, p-nitrochlorobenzene and m-nitrochlorobenzene. 结果表明:导致该厂废水毒性的关键污染物是二萘酚、对硝基氯苯和间硝基氯苯。
The synthesis process of m-nitrochlorobenzene from nitrobenzene and chlorine is discussed and optimum conditions are obtained with a yield of 71% and the m-nitrochlorobenzene purity ≥ 97%. 阐述了以硝基苯和氯气为原料合成间硝基氯苯的工艺流程及其最佳工艺条件。该工艺全程收率达71%,产品间硝基氯苯的纯度达97%以上。
