Study of water tolerance in hydrous ethanol-gasoline blends

Abstract

Water tolerance of ethanol-gasoline blends of various proportions is investigated using cosolvents such as TBA (tert-butyl alcohol), cyclohexane, heptane, acetone, iso-octane, and toluene at 300 K. Miscibility was studied using a simple experimental method for various proportions of water-ethanol gasoline blends with and without co-solvents. Results of water tolerance for each co-solvent are presented in this paper for stable mixture at room temperature
