Study on Technology and Kinetics of NDC and EG Transesterification Reaction in PEN Synthesis

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.
