摘要:
以对苯二甲酸(PTA)、新戊二醇(NPG)、羟乙基化双酚A(BPA-EO)为原料,在反应温度为160~240 ℃的熔融状态下进行缩聚以制备聚酯树脂。基于质量浓度法分别建立了一级和二级反应动力学方程,并通过反应出水量的数据计算质量浓度,进而对动力学方程进行曲线拟合。结果表明:一级和二级反应拟合曲线的线性相关系数均大于0.99,曲线拟合良好。通过进一步的统计学分析及模型辨识发现,一级反应动力学方程能更好地拟合该体系的动力学实验数据,表明PTA与NPG、BPA-EO的反应整体上遵循一级反应动力学规律,该反应的活化能(Ea)为15.67 kJ/mol,指前因子(k0)为0.211 7 min-1。
Abstract:
A polyester resin was synthesized via polycondensation in the melt state at reaction temperatures ranging from 160 to 240 ℃, using terephthalic acid (PTA), neopentyl glycol (NPG), and hydroxyethylated bisphenol A (BPA-EO) as monomers. Based on the mass concentration method, both first-order and second-order kinetic models were established.?The mass concentration was determined by measuring the amount of water evolved during the reaction, which was then used for curve fitting. The results showed that the linear correlation coefficients for both the first-order and second-order kinetic fitting curves exceeded 0.99, indicating excellent fitting quality. Statistical analysis and model identification revealed that the first-order kinetic model provided a superior fit to the experimental data, suggesting that the reaction between PTA and NPG/BPA-EO followed first-order kinetics. The activation energy (Ea) and pre-exponential factor (k0) for this reaction were determined to be 15.67 kJ/mol and 0.211 7 min-1, respectively.
