Vapor pressures above liquid and solid phases and enthalpies of vaporization and sublimation were established in a wide temperature range for three hydrocarbons that are among the model compounds for higher boiling petroleum fractions and coal liquids, The recommended values were obtained by combining the data from vapor pressure measurements with the calorimetric measurements of heat capacities and heats of fusion, and with additional data on ideal gas heat capacities. The recommended values are given for both the vapor-solid (v-s) and vapor-liquid (v-l) equilibria in terms of the parameters of the Cox vapor pressure equation allowing calculations from 223 to 623, 533 and 583 K for 1-phenyldodecane, adamantane and (5 alpha)-cholestane, respectively.
