На основе теории интегральных уравнений для частичных функций распределения проводились исследования точности определения изобарной теплоемкости н-алканов (метан, этан, бутан). Межмолекулярное взаимодействие в системах описывалось с помощью модельного сферически-симметричного потенциала Леннард-Джонса. Расчеты проведены в газовой, жидкой и сверхкритических областях. Полученные результаты хорошо согласуются с экспериментальными данными.On the basis of the theory of the integrated equations for partial functions of distribution the researches isobaric heat capacity of n-alkanes (methane, ethane, butane) were carried out. The intermolecular interaction in systems was described by means of the modelling spherically symmetric potential Lennard-Jones. Calculations are lead in gas, liquid and supercritical state. Obtained data good accuracy with experimental data.
