摘要

在303.15 K ~ 313.15 K范围内测定了4-羟基-4-甲基-2-戊酮e (DAA)与1-丁醇(B1)、2-丁醇(B2)和2-甲基-2-丙醇(B3)二元混合物的密度(ρ)、粘度()和声速(u)，确定了DAA与1-丁醇(B1)、2-丁醇(B2)和2-甲基-2-丙醇(B3)二元混合物的超摩尔体积、超等熵压缩率、粘度偏差和超吉布斯自由能。根据二元混合物中的分子间相互作用或氢键或异缔合相互作用对结果进行了分析。Prigogine-Flory-Patterson (PFP)理论被应用于识别主要的分子相互作用。对Jouyban-Acree模型结果进行了讨论，以计算密度、声速和粘度之间的平均相对偏差(MRDs)和个体相对偏差(IRD)作为精度准则

Thermo physical properties of diacetone alcohol with isomer butanols at different temperatures and correlation with the Jouyban–Acree model

ABSTRACT Excess molar volume, excess isentropic compressibility, deviation in viscosity and excess Gibbs free energy for activation of viscous flow for binary mixtures of 4-hydroxy-4-methyl-2-pentanone e (DAA) with 1-butanol (B1), 2-butanol(B2) and 2-methyl-2-propanol(B3) components selected compositions were determined from the measured values of densities (ρ), viscosities ( ), and speeds of sound (u) of pure components and their mixtures at from 303.15 K to 313.15 K. The results are analysed in terms of intermolecular interactions or hydrogen bonding or hetero-association interactions in the binary mixtures. Prigogine-Flory-Patterson (PFP) theory is applied to identify the predominant molecular interaction. Jouyban-Acree model results are discussed in terms of mean relative deviation (MRDs) and individual relative deviation (IRD) between calculated and experimental densities, speeds of sound and viscosities as an accuracy criterion

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.
