Abstract
Authors describe the performance of two new oxygenated additives, ethyl acetate and methyl acetate.  They were evaluated on the Reid Vapor Pressure (RVP), distillation curves, Drivability Index (DI), density and Research Octane Number (RON) of two types of gasoline with different chemical compositions and well defined characteristics (density, volatility and octane number).
They compared the RON and RVP values with those of ethanol and MTBE additives. Gasoline was blended with four different percentages (v/v) of the additives ethyl acetate or methyl acetate. The RON of gasoline was increased and RVP remain unchanged with the addition of the oxygenated compound. Drivability index was reduced for both additives.
