摘      要：The purpose of this paper is to study the effect of oxygenate additives into gasoline for the improvement of physicochemical properties of *** Tertiary Butyl Ether（MTBE）,Methanol,Tertiary butyl alcohol（TBA）,and Tertiary amyl alcohol（TAA） blend into unleaded gasoline with various blended rates of 2.5%,5%,7.5%,10%,15%,and 20%.Physicochemical properties of blends are analyzed by the standard American Society of Testing and Materials（ASTM） ***,TBA,and TAA increase density of the mixtures,but MTBE decreases *** addition of oxygenates lead to a distortion of the base gasoline＇s distillation *** Reid vapor pressure（RVP） of gasoline is found to increase with the addition of the oxygenated *** oxygenates improve both motor and research octane *** these four additives,TBA shows the best fuel properties.
