Analysis of the thermal conductivity of hydrocarbons and their derivatives at high pressures and temperatures

Calculated values of the thermal conductivity of liquid hydrocarbons at high temperatures and pressures up to $500$ MPa are given. The calculated values of thermal conductivity are compared with the experimental data of various authors. It is demonstrated that, at pressures up to $500$ MPa, the calculated values of the thermal conductivity agree with the experimental data within $3\%$.
