ABSTRACT

Effect of 1,1-dibutoxybutane (DBB) addition on petroleum DF (diesel fuel) performance has been studied. The study was started by preparing DBB from decomposition of 1-butanol on manganese impregnated on activated carbon (Mn/AC) catalyst at 450 °C in stainless steel reactor. The product was distilled at 200 °C and the residue obtained was analyzed by GC-MS and HSQC NMR to confirm its structure and purity. The DBB-DF mixtures were prepared at different compositions and determined their excess molar volume, homogeneity, phase stability, ignition quality, lubricity, cold flow quality, energy content, and viscosity. The addition of DBB into DF formed a homogeneous mixture and had a good phase stability. The mixtures gave positive excess molar volume values over the whole concentration ranges. The ignition quality and lubricity of the mixtures increased without lost in cold flow quality. Slight decreased in viscosity and energy content per mass unit were observed.

KEYWORDS

1,1-dibutoxybutane, petroleum diesel fuel, blending component, fuel mixture characteristics.
