毛细管气相色谱法测定工业用丙烯腈中乙腈、丙酮、丙烯醛的含量

Determination of Acetonitrile, Acetone, Acrolein in Indnstrial Products of Acrylonitrile by Caplliary Column GC

摘要: 采用气相色谱法,色谱柱为FFAP键合固定相石英弹性毛细管色谱柱(50 m×0.32 mm,0.53μm),柱温54℃,载气线速15 cm/s,测定工业用丙烯腈中乙腈、丙酮、丙烯醛的含量,回收率和RSD满足分析要求.

Abstract: The gas chromatography analysis was carried out on FFAP Wide Diameter Caplliary Column(50 m×0.53 mm,0.53 μm) to determine the content of acetonitrile,acetone and acrolein in manufactured acrylonitrile.Excellent recovery and RSD of this method was obtained.
