Abstract: Some plastic materials for liquor packaging were studied. Retention time (tR) of 17 phthalic acid esters (PAEs) was determined by gas chromatography-flame ionization detector (GC-FID). A model of quantitative structure retention relationship (QSRR) was established through the chemical metrology method and further applied to PAEs qualitative analysis of actual samples. The result shows that the model demonstrated good qualitative capacity. Our work provides a new way to study the migration behavior of PAEs in liquor and plastic packaging materials.

Key words: phthalic acid esters (PAEs), liquor, plastic packaging, retention time of gas chromatography, quantitative structure retention relationship (QSRR)
