甲酸+甲醇和甲酸+水的二元混合物的密度,包括纯液体的密度,在温度为288.15至323.13 K和大气压下的整个组成范围内进行了测量。实验数据与文献值比较,结果吻合较好。根据实验密度数据和Redlich-Kister多项式关系式得到了过量摩尔体积、偏摩尔体积和过量偏摩尔体积的体积性质。得到的结果可以用两个极性液体分子之间强烈的分子间吸引相互作用和新的氢键配合物的形成来解释。
Densities of binary mixtures of formic acid + methanol and formic acid + water, including those of pure liquids, are measured over the entire composition range at temperature from 288.15 to 323.13 K and at atmospheric pressure. The comparison of experimental data with literature values shows quite good agreement. Volumetric properties of the excess molar volume, partial molar volumes and excess partial molar volumes are obtained from the experimental density data and the Redlich–Kister polynomial equation correlations. The obtained results are interpreted by the strong intermolecular attractive interactions and the formation of new hydrogen bonded complex between the two polar liquid molecules.
