Due to the depletion of oil and the rising demand for energy, numerous researchers are focusing on discovering alternatives to fossil fuels, some of which are capable of completely or partially replacing traditional fuels. Oxygenates are often blended partially with gasoline and diesel. The main goal of this work was to assess the potential of n-propyl acetate (NPA) as a new oxygenate to gasoline and to study its effect on gasoline properties. A total of six fuel blends were formulated for this study, involving the mixing of local gasoline with varying amounts of n-propyl acetate (0%, 2%, 4%, 6%, 8%, and 10%). For comparative purposes, a gasoline sample containing 10 volume percent of absolute ethanol was also examined in this study. The volatility properties of the fuel samples were assessed through various measurements, including: distillation curve and vapor pressure, in addition to some other calculated volatility properties. Some physical and chemical properties were also studied. The obtained results displayed that blending n-propyl acetate into gasoline hardly affects the volatility of gasoline. Incorporating n-propyl acetate into gasoline results in a slight reduction in vapor pressure, as 10% n-propyl acetate causes a decrease in vapor pressure by about 2 kPa. Also, n-propyl acetate hardly affects the distillation curve of gasoline as the values of T10, T50, and T90 changed insignificantly.
