本文提出了一个与氢键液态水溶剂性质相一致的水溶液模型，并对该模型进行了修正，特别是对甲烷水溶液的能量和体积性质进行了修正。导出了甲烷水合物平衡的标准焓函数，表明水合物是CH。5.75 H20。水合物分解成冰的热与甲烷和其他水合物形成物从水溶液中的溶质析出热之间在0处给出了相关性，这从热化学上要求这些气体水合物的熔化热· 20等于n摩尔冰的熔化热。
A model for aqueous solution consistent with the nature of the hydrogen-bonded liquid water solvent is formulated andde-veloped with particular reference tothe energetic and volumetric properties of aqueous methane. The standard enthalpy functions for methane hydrate equilibria are derived and show the hydrate to be CH.-5.75 H20. A correlation at 0 is given between the heat of hydrate decomposition to ice and the heat of solute evolution from aqueous solution for methane and other hydrate-formers, which thermochemically requires that the heat of melting of these gas hydrates· 20 is equal to the heat of melting of n mole of ice.
