Apparent molar volumes and apparent molar compressibilities for d-sorbitol in (0.05, 0.1, 0.2 and 0.3) mol·kg−1 aqueous solutions of l-alanine, l-cysteine and l-histidine and NaCl have been determined from measurements of solution density at T = (288.15, 298.15, 308.15 and 318.15) K and sound velocity at T = 298.15 K, as a function of the concentration of the sugar alcohol. The data were used to obtain the limiting apparent molar volumes, limiting apparent molar compressibilities and the corresponding transfer parameters. Limiting apparent molar expansibilities and their second order derivatives and volume interaction coefficients were also estimated. These parameters are discussed in terms of d-sorbitol and co-solute (amino acid or sodium chloride) interactions in aqueous solutions.

氨基酸和氯化钠对不同温度水溶液中 d-山梨糖醇的影响:体积法和声学法

d-山梨糖醇在 (0.05, 0.1, 0.2 和 0.3) mol·kg-1 l-丙氨酸、l-半胱氨酸和 l-组氨酸和 NaCl 的水溶液中的表观摩尔体积和表观摩尔压缩率已通过溶液密度测量确定在 T = (288.15, 298.15, 308.15 and 318.15) K 和声速在 T = 298.15 K,作为糖醇浓度的函数。这些数据用于获得极限表观摩尔体积、极限表观摩尔压缩率和相应的转移参数。还估计了极限表观摩尔膨胀率及其二阶导数和体积相互作用系数。这些参数根据 d-山梨糖醇和共溶质(氨基酸或氯化钠)在水溶液中的相互作用进行讨论。
