摘　　要：为了准确检测食用油塑料桶中邻苯二甲酸酯的含量,利用响应面分析法对食用油塑料桶中邻苯二甲酸酯提取条件进行优化。探讨了不同提取试剂、料液比、提取温度、提取时间对邻苯二甲酸酯的提取影响。在单因素试验的基础上,对料液比、提取温度、提取时间3个因素进行Box-Behnken设计,以邻苯二甲酸酯提取量为响应值,通过响应面分析法对提取参数进行优化。在提取试剂为三氯甲烷,提取温度63℃,提取时间5h,塑料质量2:26.4条件下,邻苯二甲酸酯提取量为108.782mg/kg。In order to accurately detect the content of phthalic acid ester（PAEs） in plastic bottle which is used to store edible oil,the response surface methodology were used to investigate the optimal extraction conditions of PAEs from plastic bottled by soxhlet extraction.The effects of different extraction solvents,ratio of material to solvent,extraction temperature and extraction time on PAEs extraction were investigated through single factor experiment and the Box-Behnken design experiment.The optimal conditions were as follows： the extraction solvents trichlormethane,extraction temperature 63℃,extraction time 5h and the ratio of material to solvent 226.4.Under these conditions,the PAEs content was 108.782mg/kg.
