薄层色谱法在α-苯乙醇合成中的应用

Application of thin layer chromatography in the process of preparation of α-phenyi ethanol

用薄层色谱法对α-苯乙醇合成的产品进行了分离、分析。选择出最佳展开溶剂体系为:己烷:乙酸乙酯=5:3(v/v),用该展开剂可有效地分离反应原料和反应产物。并用柱色谱分离得到了纯的产品。

Thin layer chromatography was used to separate and analyze the sample in preparation of α - phenyl ethanol. The best developing solvent system is ethyl acetate：hexane = 5：3 （v/v）. The reactants and products could be separated effectively. The pure product was obtained with column chromatograph.
