Excess molar volumes and viscosities for binary mixtures of 3-heptanone + ethyl acetate, 3-heptanone + butyl acetate, 3-heptanone + tributyl phosphate,and methyl isobutyl ketone + tributyl phosphate
摘要
Abstract
Densities and viscosities of four binary mixtures of 3-heptanone + ethyl acetate, 3-heptanone + butyl acetate, 3-heptanone + tributyl phosphate and methyl isobutyl ketone + tributyl phosphate were determined from 293. 15 K to 318. 15 K under atmospheric pressure using Anton Paar DMA5000 vibrating-tube densimeter and Anton Paar AMVn automated micro viscometer. From the experimental data of density and viscosity, the excess molar volumes VE and viscosity deviation △η were calculated and correlated with the Redlich-Kister polynomial equation. The viscosities of the mixtures were correlated by Orrick-Erbar (OE) group-contribution method. And the new group-contribution parameters A and B for (-O)3-P=O group were obtained. The results show that the improved Orrick-Erbar equation is able to predict the viscosities for mixtures from their pure solvents and the deviation is acceptable in engineering applications.关键词
