Abstract
An aliphatic mono-olefin e.g. butene-2, is isomerized in the presence of a catalyst comprising essentially zirconium phosphate and at least one of chromium and thorium to produce the corresponding terminal olefin selectively.
Claims6
A process for the isomerization of an aliphatic mono-olefin hydrocarbon feed to shift an internal double bond therein to produce a corresponding terminal olefin which comprises subjecting said mono-olefin hydrocarbon feed under isomerization conditions to the action of a catalyst comprising zirconium phosphate and at least one of chromium and thorium.
