摘　　要：通过参考国内外不同的检测标准方法,设计采用索氏抽提法、微波萃取法和超声萃取法,以二氯甲烷、乙酸乙酯、四氢呋喃、正己烷和丙酮等不同溶剂提取聚氨酯(PU)合成革中的邻苯二甲酸二(2-乙基)己酯(DEHP)。比较分析不同的萃取方法对PU合成革中DEHP含量的检出影响,实验结果表明几种不同萃取方法的检测结果没有存在明显的差异。By referring to different detection standard methods at home and abroad, soxhlet extraction, microwave extraction and ultrasonic extraction were used to extract DEHP from polyurethane (PU) synthetic leather with different solvents of dichloromethane, ethyl acetate, tetrahydrofuran, n-hexane and acetone. The effects of different extraction methods on DEHP content in PU synthetic leather were compared and analyzed. The experimental results showed that there was no significant difference between the detection results of several different extraction methods.
