机器翻译免谈，翻译为英文 本论文对Wittig 反应后处理做了改进，利用副产物三苯基氧磷易结晶的特点，先用重结晶的方法除去大部分副产物三苯基氧磷后，再用柱层析色谱纯化产物。我们发现该方法不但硅胶和溶剂用量较少，而且效果很好，具有一定的环保和经济意义。 |

| In this paper, post-processing of the Wittig reaction has been improved by using 3-phenyl-product characteristics of paraoxonase easy to crystallize, first used the method to remove most of recrystallization product of 3-phenyl-paraoxon after, and then column chromatography purified products . We found that the method is not only relatively small amount of silica gel and solvent, but also a good effect, with certain environmental and economic significance. |
