Claims
- 1. A process for preparing a mixture of isomeric octenes having an average of less than about 1.6 side chain methyl groups per molecule which comprises contacting butene at a temperature between about 150.degree. to 275.degree. C. and under pressure with a catalyst comprising NiO present as a continuous, disperse substantial monolayer on the surfaces of a silica support having a surface area within the range of about 100 to 450 m.sup.2 /g, said support further containing an oxide of a trivalent metal selected form the group consisting of aluminum, gallium and indium, the quantity of said NiO present on said support being in the range of form about 0.07 to 0.12% by weight per square meter of support surface area, and the weight ratio of NiO to trivalent metal oxide present in said support being at least about 4 to 1, and recovering said octene product.
- 2. The process of claim 1 wherein the weight ratio of said NiO to said trivalent metal oxide is within the range of 4:1 to 100:1.
- 3. The process of claim 2 wherein the weight ratio of said NiO to said trivalent metal oxide is up to 30 to 1.
- 4. The process of claim 3 wherein the weight ratio of said NiO to said trivalent metal oxide is at least about 8 to 1.
- 5. The process of claim 1 containing form about 21 to about 35% by weight of said NiO and from about 1 to bout 5% by weight of said trivalent metal oxide.
- 6. The process of claim 1 wherein said support has a surface area within the range of from about 200 to 400 m.sup.2 /g.
- 7. The process of claim 6 wherein said trivalent metal oxide is aluminum oxide.
- 8. The process of claim 6 wherein said trivalent metal oxide is gallium oxide.
- 9. The process of claim 1 wherein said butene is selected from the group consisting of transbutene-2, butene-1 and cisbutene-2.
- 10. The process of claim 9 wherein said butene is transbutene-2.
