ABSTRACT

In this work densities and viscosities of 1-ethyl-3-methylimidazolium diethylphosphate ([EtMeIm]+ [Et2PO4]-) in binary mixtures with water and dimethylsulfoxide (DMSO) at atmospheric pressure and temperatures between 293.15 K 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 = 49 %.
