Abstract

ABSTRACT The density (ρ), viscosity (η), and speed of sound (u) are reported for binary mixtures of N-methylpiperazine with aliphatic primary alcohols (propan-1-ol, 2-propen-1-ol, 2-propyn-1-ol) over the entire composition range from 303.15 K to 313.15 K and at atmospheric pressure 0.1 MPa. The excess parameters (VE,κs E), deviation in viscosity, and excess partial properties ( , and ) of the components at infinite dilution were calculated from the density, speed of sound, and viscosity at experimental temperatures. All the investigated systems exhibit positive values of ∆η and ∆G *E and negative values of VE and κs E over the whole composition range. The obvious deviations attribute to the association between the primary alcohols and N-methyl piperazine molecules through the hydrogen bond of O-H· · ·N. A good agreement is obtained between excess quantities and FTIR spectroscopic data.

n-甲基哌嗪与丙烯-1-醇、2-丙烯-1-醇、2-丙烯-1-醇的热力学和光谱性质

本文报道了n-甲基哌嗪与脂肪族伯醇(丙烯-1-醇、2-丙烯-1-醇、2-丙烯-1-醇)二元混合物在303.15 K ~ 313.15 K和0.1 MPa大气压下的密度(ρ)、粘度(η)和声速(u)。根据实验温度下的密度、声速和粘度，计算了无限稀释条件下组分的过量参数(VE，κs E)、粘度偏差和过量偏性(和)。在整个组成范围内，各体系的∆η和∆G *E均为正值，而VE和κs E均为负值。这种明显的偏差归因于伯醇与N-甲基哌嗪分子之间通过O-H··N氢键的结合。过量量与FTIR光谱数据吻合较好。

期刊介绍： Physics and Chemistry of Liquids publishes experimental and theoretical papers, letters and reviews aimed at furthering the understanding of the liquid state. The coverage embraces the whole spectrum of liquids, from simple monatomic liquids and their mixtures, through charged liquids (e.g. ionic melts, liquid metals and their alloys, ions in aqueous solution, and metal-electrolyte systems) to molecular liquids of all kinds. It also covers quantum fluids and superfluids, such as Fermi and non-Fermi liquids, superconductors, Bose-Einstein condensates, correlated electron or spin assemblies. By publishing papers on physical aspects of the liquid state as well as those with a mainly chemical focus, Physics and Chemistry of Liquids provides a medium for the publication of interdisciplinary papers on liquids serving its broad international readership of physicists and chemists.
