ABSTRACT

The present study mixed twelve kinds of n-heptadecane, n-octadecane, and n-eicosane composite phase transition materials to prepare two-component mixtures. The phase transition temperature and potential heat were investigated by differential scanning calorimetry (DSC). The phase transition temperature and potential heat of the two-component mixtures were predicted using a theoretical formula, to which this study compared the theoretical and experimental data. The research results indicated congruence between the experimental and theoretical data for the phase transition temperature and potential heat of the two-component mixtures, indicating the feasibility of the theoretical formula in predicting the phase transition temperature and potential heat of normal paraffin.

摘要

本研究将十二种正十七烷、正十八烷和正二十烷复合相变材料混合制备双组分混合物。通过差示扫描量热法（DSC）研究相变温度和势热。使用理论公式预测了双组分混合物的相变温度和势热，本研究将理论和实验数据与该公式进行了比较。研究结果表明，双组分混合物的相变温度和势热的实验数据与理论数据一致，表明理论公式预测正构烷烃相变温度和势热的可行性。
