We present, as a continuation of our studies on physicalproperties of ionic liquids mixtures, experimental measurements of density for binary mixtures of1-ethyl-3-methyl-imidazolium alkylsulphate EMIM-CnS, where Cn is the alkyl chain, with ethanolat four temperatures. Samples were prepared using an inert atmosphere cabin because of ionic liquidsare hygroscopic. Densities were measured using a digital vibrating tube densimeter AntonPaar SVM300. From measured data we have extracted molar volumes and excess molar volumes.34
