| 摘 要： | 应用等温流动微量热法测定298.15 K时甲酰胺与肌醇分子在不同浓度氯化钠水溶液中的混合过程焓变及其稀释焓, 根据McMillan-Mayer理论关联得到各级异系焓相互作用系数(hxy, hxxy及hxyy). 结果表明, 甲酰胺与肌醇分子在氯化钠水溶液中的异系焓对相互作用系数hxy均为负值, 并且随着氯化钠浓度的增加, hxy的绝对值逐渐减小. |

| Abstract: | The enthalpies of mixing of formamide with myo-inositol and those of their dilution in aqueous sodium chloride solution of different concentration were determined by using flow-mix-isothermal micro- calorimetry at 298.15 K.These results were used to determine heterotactic enthalpic interaction coefficients (h_(xy),h_(xxy) and h_(xyy)) according to the McMillan-Mayer theory.The results show that heterotactic enthalpic pairwise interaction coefficients h_(xy) were negative in aqueous sodium chloride solution and became less negative with increasing the concentration of sodium chloride. |
| Keywords: | formamide myo-inositol sodium chloride heterotactic enthalpic interaction coefficient |
