摘　　要：采用气相色谱-质谱联用法（GC-MS）捡涓合成聚氨酯黏合剂原料中的2，4-甲苯二异氰酸酯（2，4-TDI）、三乙酸甘油酯（GTA）、邻甲苯胺（O-T）、4-氨基联苯（4-ABP）、2,6-二氨基甲苯（2，6-TDA）以及4-叔丁基苯酚（4-TB）。聚氯西黏合剂原料用二氯甲烷作溶剂。经超声萃取，离心分离上机。用GC-MS全扫描定性。选择离子定量。各种物质在浓度为0．05～5．00mg／L的范围内线性关系良好，相关系数芹〉0．9967；样品加标回收．添加浓度为0．10．0．20．0．40mg／kg的加标回收率为74．0％～120．1％。相对标准偏差RSD（n=6）为3．6％～6．1％；仪器检出限的范围在0．1～8．0μg／L。该方法在17min内完成了对6种物质的分离和检潮。结果准确，重现性好。并应用该方法涓定了合成聚氯腑黏合剂原料中含有的该6种物质。2,4-Diisocyanato-l-methylbenzene, triacetin, o-toluidine 4-aminobiphenyl, 2,6-toluenediamine and 4-tert-butylphenol in synthetic polyurethane adhesive was determined by using gas chromatography-mass spectrometry （GC-MS）. Raw materials which including the main agent, curing agent and solvents, using dichloromethane as solvent. After ultrasonic extraction and centrifugation, then analyzed by GC-MS. Acquisition was performed in SCAN mode for the optimization and in SlM mode for the quantification. The standard curves in the range of 0.05～5.00 mg/L and have a good linear relationship （R〉0.996 7）. When concentration of 0.10, 0.20 and 0.40 mg/kg, the recoveries were 74.0%～120.1% with RSD （n=6） in the range of 3.6%～6.1%. The detection limit were 0.1～8.0 μg/L. The method completes the separation of 6 kinds of toxic substances and detection within 17 minutes, accurate and reproducible. The method is applied to determine 6 kinds of substances in synthetic polyurethane adhesive
