Abstract
An unsaturated C.sub.5 fraction comprising at least 10% of a mixture (A) of 2-methyl-1-butene with 2-methyl-2-butene and optionally isoprene and at least 10% of a mixture (B) of other mono-olefins and diolefins is hydrogenated under controlled conditions and thereafter etherified with an alcohol having from 1 to 4 carbon atoms. A gasoline fraction of high motor octane number and low olefin content is thus obtained.
