The values of thermal conductivity and thermal diffusivity are measured for seven substances (benzene, toluene, о-n-m-xylenes, ethylbenzene, and isopropylbenzene) at temperatures T = 293–593 K and pressures P = PS – 30 MPa. The obtained values of thermal conductivity and thermal diffusivity differ from the reference values by not more than 15%. The generalizing dependences are given, which describe the thermal conductivity, thermal diffusivity, and heat capacity per unit volume of n-alkanes, alkenes, and aromatic hydrocarbons. |
