应用微量热法测定了298.15 K时肌醇在纯水和氯化钠水溶液中的稀释焓,根据McMillan-Mayer 理论计算了肌醇在不同浓度的氯化钠溶液中的2到4阶焓相互作用系数.结果表明,肌醇在氯化钠溶液中的焓对相互作用系数h2均为负值,并且随着氯化钠浓度的增大, h2的值呈增大趋势.根据溶质-溶质相互作用和溶质-溶剂相互作用对焓对相互作用系数的变化趋势进行了解释.

The dilution enthalpies of myo-inositol in water and aqueous sodium chloride solutions had been determined with flow–mix-isothermal microcalorimetry at 298.15 K. The enthalpic interaction coefficients in the different concentrations of sodium chloride had been calculated according to the McMillan-Mayer theory. The results showed that enthalpic pairwise interaction coefficients (h2) of myo-inositol are negative in aqueous sodium chloride solutions and values of h2 become more positive with increasing the concentration of sodium chloride. It could be interpreted in terms of interactions of solute with solute and solute with solvent.
