摘　　要：以2,6-萘二甲酸二甲醇酯(NDC)和乙二醇(EG)为原料,以金属盐类为催化剂,在一定条件下,研究了NDC与EG的酯交换反应,探讨了NDC与EG的酯交换反应工艺及动力学规律,不同反应温度下,NDC与EG酯交换反应遵循二级反应动力学规律,反应表观活化能为92.89 kJ/mol。The transesterification reaction of NDC（dimethyl 2,6-naphthalene dicarboxylate） and EG（ethylene glycol） was investigated under certain conditions using NDC and EG as raw materials,and metal salts as catalyst.The technology and kinetic principle of transesterification reaction between NDC and EG were discussed.At different reaction temperatures,the transesterification reaction between NDC and EG follows the kinetic principle of second order reaction,the apparent activation energy of this reaction is 92.89 kJ/mol.
