Interactions of glycine in water and in (0.10, 0.50 and 1.00) mol kg−1 aqueous sodium acetate buffer solutions of pH(1.00 and 12.40) have been investigated at different temperatures, T(K) = (298.15-318.15). Densities, 𝜌 and viscosities, 𝜂 of glycine in water and in aqueous sodium acetate buffer solutions have been measured. The obtained density data have been used to calculate apparent molar volume, 𝜙𝑣, limiting partial molar volume, 𝜙𝑣𝑜, limiting partial molar volumes of transfer,Δ𝑡𝑟𝜙𝑣. Viscosity B-coefficient, viscosity B-coefficient of transfer, Δ𝑡𝑟𝐵, activation free energies per mole of the solute,Δ𝜇2𝑜# and solvent, Δ𝜇1𝑜# have been calculated from viscosity data. Further, second order derivative of partial molarexpansion coefficient and dependence of 𝑑𝐵𝑑𝑇 coefficients on temperature is useful in measuring the structure making and breaking behaviour of solute in these systems. Pair and triplet interaction coefficients for both the properties were also calculated. Thus, the results obtained from volumetric and viscometric studies are of considerable importance to identify different type of interactions (i.e. H-bonding, van der Waals interactions) in these systems.

不同温度下醋酸钠水溶液中质子化和去质子化甘氨酸的热物理研究

甘氨酸在水中和 (0.10, 0.50 和 1.00) mol kg-1 醋酸钠水溶液 pH 值（1.00 和 12.40）中的相互作用已在不同温度下进行了研究，T(K) = (298.15-318.15)。已经测量了甘氨酸在水中和醋酸钠缓冲溶液中的密度、𝜌 和粘度、𝜂。获得的密度数据已用于计算表观摩尔体积，𝜙𝑣，限制偏摩尔体积，𝜙𝑣𝑜，限制转移的偏摩尔体积，Δ𝑡𝑟𝜙𝑣。粘度B系数、粘度B转移系数Δ𝑡𝑟𝐵、每摩尔溶质的活化自由能Δ𝜇2𝑜#和溶剂Δ𝜇1𝑜#已根据粘度数据计算得出。更远，部分摩尔膨胀系数的二阶导数和𝑑𝐵𝑑𝑇 系数对温度的依赖性可用于测量这些系统中溶质的结构形成和破坏行为。还计算了这两种性质的对和三重相互作用系数。因此，从体积和粘度研究中获得的结果对于识别这些系统中不同类型的相互作用（即氢键、范德华相互作用）非常重要。
