分别采用正己烷、环己烷、乙醚、异辛烷进行了烟用水基胶中二甘醇二苯甲酸酯萃取实验，并采用选择离子监测模式下的气相色谱-质谱联用法测定其含量．实验结果表明：以正己烷为萃取溶剂，胶样中加入1 mL水，萃取体积10 mL，振荡40 min 时萃取效果较好；测定方法线性相关系数为0．9994，检出限为0．04μg/mL，RSD为4．98％、回收率为97％～101％．

In order to determine the content of di (ethylene glycol)dibenzoate (DEDB)in water-based emulsion adhesives for tobacco,the adhesives were extracted separately with n-hexane,cyclohexane,ethyl ether,2,2,4-trimethylpentane,and determined by GC-MS under selected ion monitoring mode.The results showed that oscillating time 40 min and extraction volume 10 mL were preferable duration for n-hexane ex-traction by adding 1 mL water into the sample;the calibration curves of the DEDB exhibited good linear re-lations(R2 =0.999 4),the limits of detection 0.04μg/mL,RSD=4.98%,and the recoveries ranged from 97%~101%.
