MINIMIZING EVAPORATION OF LIGHT HYDROCARBONS FOR IRAQI GASOLINE USING FATTY ACID ESTERS COMPOUNDS, SYNTHESIS AND CHARACTERIZATION

Abstract

The work includes synthesis of new fatty acids esters and thioesterby the reaction of 5-hydroxy isophthalic acid, glycolic acid and thioglycolic acid with fatty acidschloride,all reactions were monitored by TLC. Synthesized compounds were characterized by FT-IR, 1HNMR, 13CNMR and mass spectroscopy. The possibility of reducing evaporation light hydrocarbons from Iraqi gasoline was performed by introducing micro-quantities of synthesized esters as a new method. The efficiency of this method was evaluated by measuring saturated vapor pressure (Reid Vapor Pressure) at 37.80C, while surface tension at 25 0C of the concentrations (1-10 mg L-1). The results indicate a successful attempt to use esters and thioesters compounds as reduce pressure agents. Optimal concentration was estimated by the lowest saturated vapor pressure.
