Immiscible binary liquid fuels of ethanol and oil could be homogenized by a
ddition of a small amount of methyl tert-butyl ether, ethyl tert-butyl ethe
r, tert-amyl methyl ether, tetrahydrofuran, tetrahydropyran, or 1,4-dioxane
. As oils, diesel fuel, soybean oil, and rape oil were used. Liquid-liquid
solubility curves for the ternary systems of ether, ethanol, and oil (refer
red to as ether + ethanol + oil) were measured at 298.15 K.
