摘　　要：本文采用XF－60文联弹性石英毛细管柱及407有机担体填充柱气相色谱法可全分析丙烯腈中有机杂质。通过对柱长、担体粒度、液膜厚度、柱温和载气流量的选择，确定出最佳色谱条件。最小检出限均可达0．1mg／L。定量测定结果的重现性良好。A method for the `determination of organic impurities in acrylonitrile hy XE 60capillary chromatography and 407 porous polymer packed column chromatography is de scribed. Optimum chromatographic conditions have been established by selecting column length. support grain size. liquid fiim thickness, column temperature, and carrier gas flowrate. The dotection limit is 0.1 mol/L. The reproducibility of analytical results is good.
