| Improvement of Solvent for Synthesis of Niphensamide |
| LIU Yi-ming; et al.（Department of Chemical Engineering; Yueyang University; Hunan Yueyang; 414000; China） |
| Abstract：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. |
