Abstract
Novel catalysts are disclosed for the selective dehydration of 2-alcohols to .alpha.-olefins. In one case, the catalyst comprises at least one catalytic metal oxide on a low surface area aluminum oxide-containing support. In another case, the catalyst comprises a mixture of thorium oxide and cerium oxide on a base treated aluminum oxide containing support. There is also disclosed a novel process for obtaining high purity 4-methyl-1-pentene involving the dehydration of 4-methyl-2-pentanol followed by disproportionation with ethylene.
Claims35
A process for preparing an .alpha.-olefin comprising contacting a dehydratable 2-alcohol under suitable reaction conditions with a catalyst selected from the group consisting of catalysts comprising a catalytically effective amount of at least one catalytic metal selected from the group consisting of metals having atomic numbers of 21, 39, 58-71, or 90 supported on a support consisting essentially of an oxide of aluminum having a surface area no greater than 20 m.sup.2 /g.
A process for preparing an .alpha.-olefin comprising contacting a dehydratable 2-alcohol under suitable reaction conditions with a catalyst comprising base treated aluminum oxide having deposited thereon a catalytically effective amount of a mixture of thorium oxide and cerium oxide.
