Furan compounds have properties such as oxygenate additive to enhance octane number of gasoline. The procedure was a furan synthesis through an acidic hydrolysis of the polysaccharide materials from pineapple plantation residues. The products obtained were a complex mixture of mostly 3-(2-furanyl)-2-propenoic acid, 4-(2-furanyl)-3-butene-2-one and 5-methyl-furfural. Thermodynamic and rheolgical properties of the mixture in toto were measured, as well as its oxygenating capability. The results showed a two units enhancer oxygenate additive for naphta, potentially safe for transport and handling, presenting the following characteristics: specific gravity 1,22559±0,00002, kinematic viscosity 0,0127±0,0001 Stokes, enthalpy of vaporization 39,1±0,1kJ mol-1, isothermal compressibility (1,0±0.2)10-9Pa-1, rate of evaporation 0,03±0,02g s-1 m-2 and Hildebrand solubility parameter 18,0±0,1(J cm-3)1/2.
