Abstract

ABSTRACTThe excess molar volume, excess isentropic compressibility, and deviation in viscosity have been investigated from density, speed of sound and viscosity measurements of three binary mixtures of 2-methyl-1-butanol (B) with 1,2–disubstituted ethanes (1,2–dichloroethane(B1), ethylenediamine (B2) and monoethanolamine (B3) over entire composition range at various temperatures of 303.15 K −313.15 K. The excess / deviation has been fitted by a Redlich-Kister equation and the results are discussed in terms of attractive forces and chemical forces. The excess properties are found to be either negative or positive depending on the physical and chemical forces and the nature of the liquid mixtures. These systems studied exhibit very strong cross-association through hydrogen bonding. 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.KEYWORDS: 2-methyl-1-butanol12-disubstituted ethanesPFP theoryJouyban–Acree model Disclosure statementNo potential conflict of interest was reported by the authors.

2-甲基-1-丁醇与二取代乙烷在不同温度下的热物理性质及其与jouyban-acree模型的相关性

摘要在303.15 K ~ 313.15 K的不同温度下，对2-甲基-1-丁醇(B)与1,2 -二取代乙烷(1,2 -二氯乙烷(B1)、乙二胺(B2)和单乙醇胺(B3)的三种二元混合物在整个组成范围内的密度、声速和粘度进行了测量，研究了过量摩尔体积、超额等熵可压缩性和粘度偏差。用Redlich-Kister方程拟合了超差/偏差，并用引力和化学力对结果进行了讨论。根据物理和化学力以及液体混合物的性质，发现多余的性质是负的或正的。所研究的这些体系通过氢键表现出很强的交联。Prigogine-Flory-Patterson (PFP)理论被应用于识别主要的分子相互作用。在Jouyban-Acree模型中，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)作为精度标准来讨论结果。关键词:2-甲基-1-丁醇- 12-二取代乙烷espfp理论jouyban - acree模型披露声明作者未报告潜在利益冲突。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
