The use of alcohols and organotin compound for improving the octane number of gasoline

Abstract

The synthesis of tetraalkyltin by Grignard method gave high yield (>80%) and pure product. The determination of octane numbers of gasoline blended with tetraalkytin and alcohols showed that they enhanced antiknock property. The octane number of the blends of tetraalkyltin increased 1.2-1.9 units by adding tin 1-2 g/L, alcohols increased 2-4 units by adding alcohols 5%-10% and tetraalkyltin mixed alcohols increased 2-5 units.
