Claims
- 1. A novel lubricant composition comprising the reaction product of olefinic dimer, or mixtures thereof, in contact with a Group 6 metal oxide disproportionation catalyst on a solid support under disproportionation reaction conditions, said dimer comprising the product of the oligomerization of C.sub.6 -C.sub.20 alpha-olefins in contact with reduced chromium oxide catalyst on silica support, wherein said disproportionation catalyst has been treated by oxidation at a temperature of 200.degree. C. to 900.degree. C. in the presence of an oxidizing gas and then by treatment with a reducing agent at a temperature and a time sufficient to reduce said catalyst.
- 2. The composition of claim 1 wherein said metal oxide comprises tungsten oxide and said solid support comprises silica.
- 3. The composition of claim 1 wherein said disproportionation reaction conditions comprise temperature between 0.degree. C. and 600.degree. C. and a feed to catalyst ratio between 1:1 and 100:1.
- 4. The composition of claim 3 wherein said conditions are about 300.degree. C. and 50:1 feed to catalyst ratio.
- 5. The composition of claim 1 wherein said reducing agent comprises carbon monoxide and said oxidizing agent comprises air.
- 6. The composition of claim 1 wherein said alpha-olefins comprise 1-decene and said dimer comprises C.sub.20 dimer.
