Description
Summary:In this work, the densities and viscosities of 1-ethyl-3-methyl­imida­zolium di­ethyl­phosphate ([EtMeIm]+ [Et2PO4]−) in binary mixtures with water and dimethyl sulfoxide (DMSO) at atmospheric pressure and temperatures between 293.15 and 373.15 K were determined. The properties were measured in a Stabinger densimeter–viscosimeter SVM 3000 model. In addition, a correlation of the viscosity data was made with a modification of the Grunberg and Nissan correlation, in which corrections for the interaction between the ionic liquid and the water, DMSO, or both were introduced. For the mixture H2O + ([EtMeIm]+ [Et2PO4]−), the %AARD is 13% with a maximum deviation (%max) of 49%; for the mixture DMSO + ([EtMeIm]+ [Et2PO4]−), the %AARD is 9.5% and the %max is 49%.
