| 摘 要：利用高效液相色譜-外標定量法測試了聚對苯二甲酸乙二醇酯（PET）中抗氧劑2246和乙醛向酒精溶液中的遷移行為。實(shí)驗條件對二者的遷移行為有明顯影響，其中降低實(shí)驗溫度和酒精濃度可以抑制二者在實(shí)驗條件下的遷移。當酒精濃度為8%，實(shí)驗溫度為20℃，測試時(shí)間為90 d時(shí)，乙醛的遷移量為0.11 μg·g-1，抗氧劑2246的遷移量為0.19 μg·g-1，均處于較低水平。雖然提高酒精濃度和實(shí)驗溫度會(huì )造成二者遷移量上升，但在40℃下，將PET板材浸泡于濃度為60%的酒精溶液中90 d后，乙醛和抗氧劑2246的遷移量也僅為0.21 μg·g-1和0.70 μg·g-1。 |

| Abstract：The migration behaviors of antioxidants 2246 and acetaldehyde to alcohol from PET were measured using high performance liquid chromatography combined with external standard quantitative method. The experimental conditions obviously affected the migration behavior of antioxidants 2246 and acetaldehyde. Low experimental temperature and low alcohol concentration could suppress the migration. When the alcohol concentration was 8%, the experimental temperature was at 20℃ and the test time was 90 days, the migration of acetaldehyde was as low as 0.11 μg·g-1, and the migration of antioxidant 2246 was as low as 0.19 μg·g-1. Although increasing the concentration of alcohol and the temperature of the experiment resulted in the increase in the migration, the migration of acetaldehyde and antioxidant 2246 was 0.21μg·g-1 and 0.70 μg·g-1 at 40℃, 90 days after immersion in the alcohol solution with a concentration of 60%. |
