Additive physical properties in hydrocarbon mixtures

“…If these equations are fulfilled exactly,, then for the mixture having an average hydrogen content of y per cent and unsaturation (olefinic and aromatic, as weight of hydrogen per unit weight of sample) of h, the following equation holds exactly: / = A + By + Cjj + Dh (3) in which A, B, C, and D are constant for any given property. In practice, the conditions hold approximately for certain properties; hence the equation likewise holds only approximately.…”
