摘　　要：用气相色谱法测定溶剂中丙烯腈的含量。用化学方法除去样品中的硫氰酸根离子，再以Ｃｈｒｏｍｏｓｏｒｂ１０１为固定相，使样品中各组分分开，用氢火焰离子检测器检出其中的丙烯腈，通过计算准确测得样品中丙烯腈含量。方法重复性可达到１．４×１０－６，最大相对误差为５．５％To determine acrylonitrile content in solvent with gas chromatography. Chemically remove sulfocyanic acid radical ion in the sample and then use Chromosorb 101 as fixed phase to separate constituents in sample, with hydrogen flame ionization detector to determine acrylonitrile and the content of which in sample can be accurately calculated. The repeatibitity is 1.4 ×10 and the maximum relative error is 5.5%.
