溶剂对硝苯柳胺合成影响的研究

Improvement of Solvent for Synthesis of Niphensamide.

研究了用二甲苯代替氯苯用作合成硝苯柳胺的溶剂 ,实验结果表明 ,用二甲苯不但能降低合成成本、降低溶剂的毒性和污染 ,而且还能使合成工艺得到优化 ,提高产品的纯度和产率 ,具有很好的推广应用价值。

In this paper, the experimental results showed that the solvent of xylene instead benzene chloride for synthesis of Niphensamide can not only reduced the cost of material, the toxicity and polution, but also improved the condition of solvent separation, yield and the recovery of solvent. And the solvent after surparation can be reused without purication. It is suitable to industry production.
