摘　　要：乙二醇单甲醚、乙二醇单乙醚、N,N-二甲基甲酰胺、乙二醇二乙醚、乙二醇乙醚乙酸酯、二乙二醇二甲醚和N-甲基吡咯烷酮是一类优良的有机溶剂,但由于其潜在的生殖毒性,被REACH定为高关注物质。利用气相色谱-质谱法建立检测轻工产品(纺织品、皮革、竹木制品)中这7种挥发性有机溶剂的简单方法。提取方法为30℃甲醇超声水浴提取。方法的回收率高于91.7%。这个方法被成功应用于测定轻工产品中的这7种挥发性有机溶剂。Excellent organic solvents （ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, N, N-dimethyl formamide and ethylene glycol diethyl ether, glycol ether acetate, diethylene glycol dimethyl ether and N-methyl pyrrolidone） were widely attented by REACH, due to their potential reproductive toxicity. A simple method was followed by Gas chromatography-mass spectrometry （GC-MS） which had been developed for the determination of them in light industrial products （textiles, leathers, bamboo and wood products）. Methanol was used as extraction solvent for the ultrasonic extraction at 30℃. The recoveries were higher than 91.7%. The proposed method was successfully applied to the determination of the target compounds in light industrial products with a higher sensitivity.
