GASOLINE COMPOSITION CONTAINING COMPOUNDS DERIVED FROM SELECTIVE OLIGOMERIZATION OF ISOBUTENE

摘要

Liquid mixture suitable as gasoline characterized in that it has a RON octane number equal to or higher than 90 and a MON octane number equal to or higher than 80 and that it essentially consists of: - a typical gasoline cut, having a boiling point ranging from 30 to 220.degree.C, consisting of hydrocar- bon compounds; - one or more compounds deriving from the selective oligomerization of isobutene, which may optionally have been at least partially hydrogenated, in a quantity ranging from 0.5 to 20% by weight, wherein the dimers of isobutene and possible co- dimers of isobutene with n-butenes are in a quantity of at least 80% by weight; - optionally ethanol in a quantity ranging from 0 to 10% by weight, the complement to 100 being said gasoline cut.
