In order to research and evaluate the safety of food packaging of plasticizer Di-2-ethylhexyl phthalatein PVC film, the migration rate of DEHP from PVC film into water food simulants (distilled water, 65% aqueous ethanol, 20% aqueous ethanol, 4% aqueous acetic acid) was studied at 17, 30, 40, 50 and 60℃ by Gas Chromatography.

为了研究评判PVC膜中增塑剂邻苯二甲酸二异辛酯在食品包装中的安全性，采用气相色谱仪测试了几种水性溶剂（蒸馏水、65%乙醇、20%乙醇、4%乙酸）在不同温度（17℃、30℃、40℃、50℃、60℃）下对PVC膜中增塑剂DEHP的溶出率。

Different from many other researches the Henkel-Esterification process was studied here which starts from 1,8-naphthalenedicarboanhydride. In the Henkel reaction of 1,8-naphthalenedicarboanhydride to 2,6-naphthalenedicarboxylic acid (abbreviated as 2,6-NDA) non-cadmium catalytic system was used. In atmosphere of carbon dioxide 1,8-naphthalenedicarboanhydride can be effectively converted to 2,6-NDA in the temperature range of 300~340℃ with zinc carbonate as catalyst and the yield of 2,6-NDA can reach more over 62%.

和国内外绝大多数研究不同的是，论文结合公司自身的原料资源优势和长远规划，提出了从工业苊深加工产品—1，8-萘二甲酸酐出发，经过非镉系催化剂催化转位，然后再进行非酸催化酯化合成2，6-萘二甲酸二甲酯的工艺路线，并对工艺过程中涉及的成盐过程、催化转位反应、酯化反应等进行工艺参数的重点考察，对合成产物进行分析确证。
