Abstract
A process is disclosed for upgrading C.sub.5 -C.sub.8 olefin-containing gasoline to a high octane motor gasoline blending component. C.sub.3 -C.sub.4 olefins are hydrated to alcohols and then selectively removed from the aqueous hydration reactor effluent stream via liquid extraction with the gasoline feedstream. The alcohol enriched gasoline extract stream is then etherified and unreacted alcohols are extracted to yield a high octane gasoline blending component free of metal-bearing additives.
