摘　　要：冰水冷却下将3-氨基-1,2-丙二醇加入到衍生化试剂三氟乙酸酐中,充分振荡,50℃反应30min,冷至室温后直接进气相色谱检测,面积归一法定量。在选定的实验条件下,加标回收率大于99%,测定峰面积的相对标准偏差为0.6%。该方法也可应用于3-氯-1,2-丙二醇、2-氨基-1,3-丙二醇、1,3-二氨基-2-丙醇等其它高粘度物质的检测。3-Amino-l,2-propanediol was added into trifluoroacetic anhydride with an ice-water bat, then reacted for 30 min under 50℃. The reaction solution was detected by gas chromatography. The recovery of standard addition was more than 99% ,and the relative standard deviation of peak area was 0.6% in the experimental conditions. This method could be used in the detection of other high viscosity materials, such as 3-chloro-1,2-propanediol, 2-amino-1, 3-propanediol, 1,3-diamino-2-propanol and so on.
