摘要 采用热裂解气相色谱-质谱联用技术(Py/GC-MS)建立了聚乳酸(PLA)纤维和3种聚酯纤维(聚对苯二甲酸乙二酯(PET)纤维、聚对苯二甲酸丙二酯(PTT)纤维、聚对苯二甲酸丁二酯(PBT)纤维)的鉴别方法。裂解温度为700℃时,可以最大限度同时显示聚乳酸纤维和聚酯纤维样品特征。PLA纤维、PET纤维、PTT纤维和PBT纤维分别鉴别出8种、14种、16种和13种主要裂解产物。PLA纤维的特征性裂解产物是:D,L-丙交酯、内消旋丙交酯;PET纤维的特征性裂解产物是:苯甲酸乙烯酯、苯二甲酸双乙烯酯、二苯甲酸-1,2-乙二醇酯、苯甲酸乙酯;PTT纤维的特征性裂解产物是:苯甲酸丙烯酯、间苯二甲酸二烯丙酯、1,4-苯二甲酸-二-2-丙烯基酯、二苯甲酸-1,3-丙二醇酯;PBT纤维的特征性裂解产物是:苯甲酸丁烯酯、1,4-苯二甲酸-双-3-丁烯酯。 An identification method of poly(lactic acid) fiber and three polyester fibers was established by pyrolysis gas chromatography - mass spectrometry (Py/GC-MS). The polyester fibers includes polyethylene terephtalate (PET) fiber, polytrimethylene terephthalate (PTT) fiber and polybutylene terephthalate (PBT) fiber. As shown by the experimental results, it was better to choose 700 ℃as the pyrolytic temperature in the identification, as more significant characteristic informations were displayed simultaneously. PLA fiber, PET fiber, VFT fiber and PBT fiber were identified 8 species, 14 species, 16 species and 13 species of main pyrolysis products. PLA fiber's characteristic pyrolysis products were meso-laetide and D,L-lactide. PET fiber's characteristic pyrolysis products were vinyl benzoate, diethylene terephthalate, dibenzoate- 1,2 -ethanediol and ethyl benzoate. FIT fiber's characteristic pyrolysis products were propenyl benzoate, diallyl isophthalate, diallyl terephthalate and 1,3-propanediol dibenzoate. PBT fiber's characteristic pyrolysis products were butenyl benzoate and bis-3-butenyl- 1,4-terephthalate.
