Surface tension for the ternary system dimethyl carbonate + p-xylene+ n-octane from 288.15 K – 308.15 K.

Abstract

Dimethyl carbonates are useful in organic solvents because the chemical used as solvent extraction processes, as well as battery technology [1,2]. Molecules carbonate base, containing an aromatic and aliphatic portions have special industrial interest as gasoline additives and as lubricants in the replacement of chlorofluorocarbons (CFCs) with the new refrigerants HFC (hydrofluorocarbons) [3-6]. These industrial uses are the main reason why there has been a considerable increase in theoretical and experimental investigations of dialkyl carbonates and mixtures there of with other compounds [7-9], so our research group has also focused on the study (measurements and models) of mixtures containing carbonate molecules. The interest in the study of this mixture lies in the fact that dimethyl carbonate [10,11] has been considered as a replacement of traditional oxygenated gasoline additive, because it is a non-toxic and environmentally friendly product capable of reducing pollutant emissions as carbon monoxide. This work presents a study of experimental surface tension for the ternary system dimethyl carbonate + p-xylene +n-octane binary system, in the temperature range from 288.15 K to 308.15 K and at atmospheric pressure. The surface tension values were fitted by a variable degree polynomial [10-12].
