Information available in the literature on vapor pressures, saturated vapor and liquid densities, and critical constants, for different hydrocarbons, has permitted the calculation of δ, the solubility parameter advanced by Hildebrand, at temperatures up to and including the critical point. For these hydrocarbons, the residual quantity, δ‐δ c was found to depend on 1‐ T R according to the relationship,\documentclass{article}\pagestyle{empty}\begin{document}$$ \delta ‐ \delta _c = k[1 ‐ T_R ]^{0.447} $$\end{document}where k appears to be a constant within different classes of hydrocarbons. Values of δ calculated with this equation were compared with the corresponding values used to develop it, and produced an average deviation of 0.85% for 153 values considered which represented 17 hydrocarbons.
