摘要
用气相色谱法测定了腈纶厂聚合装置混合单体中丙烯腈（ＡＮ）和醋酸乙烯酯（ＶＡ）的含量。用该方法测定出变异系数ＡＮ为０．０９％，ＶＡ为０．５６％，回收率ＡＮ为９６％～１０６％，ＶＡ为９９％～１０５％。
he content of acrylonitrile(AN) and vinyl acetate(VA) in the mixed monomer of acrylic fiber plant was determined by gas chromatography method. The experimental results showed that for this method the relative standard derivations and recovery rates of AN and VA were 0.09%,96%￣106%,0.56%,99%￣105%, respectively.
