The experimental freezing‐point data of the methane‐ n ‐hexane and the methane‐ n ‐octane binaries are presented and compared with the methane–carbon dioxide system investigated by Donnelly and Katz. A step‐by‐step variation of the freezing point in the paraffin homologous series is exploited to provide reasonably accurate extrapolation of the experimental data on the two binaries and scattered freezing‐point data on the methane‐ n ‐butane mixture to other paraffin hydrocarbon mixtures of methane in which the heavier constituent ranges from ethane to n ‐nonane, inclusive. A composite graph of the freezing points of the various binaries with methane, from ethane to n ‐nonane, is presented.
