The statistical thermodynamics of group interaction previously developed for liquids of chain molecules is extended to their mixtures. The theory is applied to pure n‐alkanone liquids, and solutions of n‐alkanone/n‐alkanone and n‐alkane/n‐alkanone systems. The interaction properties of methyl and methylene groups are taken from our previous work. The interaction properties of carbonyl group are determined and reported in this work. The calculated density and heat of vaporization of pure n‐alkanone‐2 liquids agrees with data over a wide temperature range. The calculated heats of mixing of n‐alkanone/n‐alkane and n‐alkanone/n‐alkanone solutions agree with available data.
