摘要
PET和 PBT树脂因其结构上的相似性 ,红外光谱法定性判定常有偏差。本文研究了以裂解气相色谱法鉴定 PET和 PBT树脂。采用不锈钢毛细管柱 ,优化了裂解温度和色谱分离条件 ,得到特征色谱图。方法简单、快速、准确。
The structures of PET and PBT are so similar that it is difficult to identify them by Infrared spectroscopy.A pyrolysis gas chromatographic method with steer capillary column was established for identification of PET and PBT.The temperature of pyrolysis and the separation conditions were optimized.The method is simple,rapid and accurate.
