Theoretical And Experimental Research On The Thermal Properties Of N-Alkanes

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.
