摘要: The experimental data obtained by the authors on isobaric heat capacity of n-alkanes saturation curve in liquid phase and literature C"pof hydrocarbons representing different homologous series are used to analyze known formulas recommended for predictions C"p. It is demonstrated that, order increase accuracy calculations, one needs, first all, refine description vicinity temperature triple point. universal behavior dependence C"pin point revealed. Based these findings, new generalized equations developed, which calculation range from critical.
