反式1，4-环己烷二甲醇的非等温结晶动力学研究

摘要

The non-isothermal crystallization of trans-1,4-cyclohexanedimethanol (trans-CHDM) was investigated by differ-ential scanning calorimetry (DSC). Various macro-kinetic models were applied to fit the experimental data of crystallization kinetics under non-isothermal conditions. The results revealed that the Jeziorny approach and Ozawa methods could adequately describe the non-isothermal crystallization process of trans-CHDM, so they could be used to explore some meaningful inter-pretation of the kinetic parameters for trans-CHDM crystallization. Moreover, the activation energy (ΔE) of non-isothermal crystallization for trans-CHDM was also determined according to the Kissinger method.%采用差示扫描量热法（DSC）考察了反式1，4-环己烷二甲醇（简称反式CHDM）的结晶过程，用不同的模型方程进行了非等温结晶动力学模拟探索。研究结果表明：Jeziony模型和Ozawa方程均能很好地描述反式CHDM的结晶过程，根据模型分析取得较好的线性关系和动力学参数。同时用Kissinger方法计算了反式CHDM的非等温结晶活化能，为辽阳石化的CHDM结晶工业化生产提供数据和理论支持。
