摘要:用以前所提出的液体通用混合模型[7],导得了一个醇-烃液体混合物的超额焓与组成间的关系式,并由三个丁醇异构物与环己烷系统进行了检验。为了确定组分的特性常数,还实验测定了仲丁醇、异丁醇和叔丁醇在30~80℃温度范围的热压力系数。检验结果表明,这个关系式能满意地描述这些液体混合物的超额焓随组成的变化规律。
By the general mixing model of liquids suggested by our previous work[7]a relation between the excess enthalpy and the composition for alcohol-hydrocarbon mixtures is obtained.Three liquid mixtures of isomeric butanols+cyclohexane are used to test the relation.The thermal pressure coefficients of 2-butanol,2-methyl-1-propanol and 2-methyl-2-propanol are measured over the temperature range of 30~80℃ in order to determine their characteristic parameters.The results show that the relation can be used to describe the variation of excess enthalpy with the composition for these liquid mixtures.
