The effect of methylfurans on the physicochemical and performance characteristics of finished motor gasoline

Resumo

The physicochemical and performance characteristics of blends of commercial gasoline with the promising oxygenate antiknock additives 2-methylfuran and 2,5-dimethylfuran have been studied. The key parameters determining the compliance of gasoline with the GOST R 51866-2002 (EN 228-2004) requirements have been measured. A high antiknock activity of the test compounds has been demonstrated, and blending octane numbers have been calculated. It has also been found that the addition of 2-methylfuran and 2,5-dimethylfuran to gasoline substantially deteriorates its oxidation stability and increases gum content.
