摘　　要：应用微量热法测定了298.15K时肌醇在纯水和卤化钠水溶液中的稀释焓,根据McMillan-Mayer理论,计算了肌醇在溶液中的二到四阶焓相互作用系数.结果表明,肌醇在卤化钠溶液中的焓对相互作用系数h2均为负值,并且随着卤素阴离子半径的增大,h2的绝对值呈增大趋势.The dilution enthalpies of myo-inositol in water and in aqueous sodium halide solutions have been determined with flow-mix-isothermal microcalorimetry at 298.15 K. The enthalpic interaction coefficients in the range of sodium halide solutions have been calculated according to the McMillan-Mayer theory. The results show that enthalpic pairwise interaction coefficients （h2） of myo-inositol are negative in aqueous sodium halide solutions and absolute values of h2 increase with elongation of radius of halogen anion.
