Patent number: 5144082Abstract: It is disclosed that aromatic compounds can be alkylated with mono-olefinic HVI-PAO dimer in contact with an acidic catalyst to produce novel alkylated aromatic compositions. It has been found that the novel HVI-PAO dimer alkylated aromatic compositions exhibit an extraordinary combination of properties relating to low viscosity with high viscosity index and low pour point which renders them very useful as lubricant basestock. Further, it has been found that the novel alkylaromatic compositions of the present invention show improved oxidative stability. Depending upon the substituent groups on the aromatic nucleus, useful lubricant additives can be prepared for improved antiwear, antioxidant and other properties. HVI-PAO dimer is prepared as a product or by-product from 1-alkene oligomerization using reduced chromium oxide on solid support. Particularly disclosed are the alkylphenols prepared by the process of alkylation a phenol at the aromatic nucleus with the novel oligomer.Type: GrantFiled: April 17, 1991Date of Patent: September 1, 1992Assignee: Mobil Oil CorporationInventors: Thomas R.
