•Thermophysical properties of biofuel components and intermediates are compiled.•Compilation contains critical properties, heat capacities, and thermal conductivities.•Recommended values of the critical temperatures and pressures were determined.•Polynomials for calculating heat capacities and thermal conductivities were obtained. Experimental data on the critical temperature, critical pressure, heat capacity, and thermal conductivity of the compounds involved in the production of biofuels have been compiled and critically evaluated. The compilation contains the critical temperature and critical pressure of 56 compounds, the heat capacity of 63 compounds, and the thermal conductivity of 35 compounds and covers the period from 1886 to September 2023. The recommended values of the critical temperatures and pressures have been determined. The parameters of correlating polynomials for the temperature dependence of heat capacities and thermal conductivities have been obtained. The compounds under consideration are the components of biofuels or platform chemicals. Some methyl and ethyl esters of saturated and unsaturated acids, furanic compounds, levulinic acid and alkyl levulinates, gamma-valerolactone, alpha-angelica lactone, triglycerides, and several alkyl pentanoates are among the compounds studied.
