| 摘 要： | 采用溶解平衡的方法测定了氨气在甲醇、乙二醇及其混合溶剂中的溶解度,得到了100 kPa和70.0 kPa压力,温度从278.1 K到338.1 K共7个水平,混合溶剂组成(用乙二醇质量分数表示)从0到1.0共11个水平的143组氨溶解度数据。基于扩展的拉乌尔定律和扩展的亨利定律提出了表达上述条件下,混合溶剂中氨溶解度的热力学模型,对实验数据进行关联,取得了较好的结果。 |

| Abstract: | The experimental results of 143 points solubility data of ammonia in liquid mixture of methanol and ethylene glycol were reported,in which eleven solvent compositions were considered from 0 to 1.0(as mass fraction of ethylene glycol) at seven temperatures of 278.1,288.1,298.1,308.1,318.1,328.1,and 338.1 K,solubility pressures of 100 and 70.0 kPa,respectively.A thermodynamic model based on the extended Raoult′s law and the extended Henry′s law was proposed to describe the ammonia solubility in the mixture solvent under the experimental conditions,the calculated solubility shows a good agreement with the experimental data. |
| Keywords: | ammonia solubility mixed solvent ethylene glycol methanol |
