摘要
采用振荡管式数字密度计分别测定甲醇、乙醇、正丙醇、异丙醇、正丁醇和异丁醇与 N-甲基哌嗪组成的二元体系在 2 98.15 K下的密度 ,计算了超额摩尔体积、超额偏摩尔体积、表观摩尔体积、偏摩尔体积等体积性质 ,从分子相互作用角度讨论了这些二元体系的体积性质的变化规律 ,为
The densities of binary mixtures of N-methylpiperazine with alcohols, including methanol, ethanol, 1-propanol, iso-propanol, 1-butanol, and iso-butanol, were measured at 298.15K over the whole mole fraction rage by means of a digital vibrating-tube densimeter. Excess molar volumes of mixtures, excess partial volumes, apparent volumes and partial molar volumes of both components were calculated. The regularity for the changes of volumetric properties against the composition is discussed from the viewpoint of molecular interaction. Some fundamental data and information for the further study and development of N-methylpipwrazine are presented.
