机器翻译者请版主扣金币，中文译为英文 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。 |

| The present paper has made the improvement to the Wittig response post-processing, easy to crystallize the characteristic using the by-product triphenyl oxygen phosphorus, uses the heavy crystallization the first method after the majority of by-product triphenyl oxygen phosphorus, then uses the column to chromatographically analyze the chromatograph purification product. Not only we discover this method the silica gel and the resolver amount used are few, moreover the effect is very good, has certain environmental protection and the economic significance. |
