Established the qualitative and quantitative method for the determination specific migration of benzene compounds （migration of 13 kinds of benzene compounds in ethanol aqueous solution） in water and 4% acetic acid aqueous solution in AS/ABS by headspace-gas chromatography tandem mass spectrometry containing benzene， toluene， ethylbenzene， p-xylene， m-xylene， o-xylene， 1，3，5-trimethylbenzene， styrene， cumene， n-propylbenzene， sec-butylbenzene， butylbenzene， 1，2，4-trimethylbenzene and 1，2，3-trimethylbenzene. By optimizing the separation ratio， carrier gas flow rate， programmed heating rate， equilibrium temperature and time， the chromatographic conditions， the DB-WAXMS column （30 m × 0.25 μm × 0.25 mm） was used to separate benzene， xylene， tritoluene and propyl benzene， effectively. The linear correlation coefficient was more than 0.9950， the detection limit with 10S/N was 0.6-2.1 μg/kg， the recovery rate was 80.2%-118.3%， the relative standard deviation 3.6%-9.7%， the rapid qualitative and quantitative analysis of 14 benzene compounds in AS/ABS was realized. Investigated the migration law of benzene compounds in AS/ABS of food contact products at temperatures of different temperature and different time， the higher the temperature， the greater the specific migration of benzene compounds. At the same time， the migration model of benzene compounds at different temperatures is established and the kinetic parameters such as diffusion coefficient DP， characteristic parameter Ap， activation energy Ea are determined. Finally， the establishment of a mathematical model for risk assessment of benzene compounds in AS/ABS of food contact materials provides a basis for risk control of benzene compounds.
