One-step dehydration and isomerisation of n-butanol to iso-butene over zeolite catalysts.

The efficient one-step conversion of n-butanol to iso-butene over zeolite catalysts by combined dehydration and isomerisation has been demonstrated. The medium pore-size unidirectional channel zeolites Theta-1 and ZSM-23 show high conversion and stable selectivity to iso-butene.
