ABSTRACT:
The thermal and oxidative stability of HVI-PAO olefin oligomers is improved by alkylation in the presence of a solid, porous, acidic alkylation catalyst defined by a specific X-ray diffraction pattern. A preferred catalyst is the synthetic zeolite MCM-22. The olefinic oligomers used as alkylating agents are prepared from 1-alkene oligomerization in contact with a reduced metal oxide, preferably reduced chromium oxide, catalyst on support such as silica. Aromatics which may be used in the reaction include monocyclic aromatics such as benzene and toluene as well as bicyclic aromatics such as naphthalene. Substituted aromatics may be used in order to introduce functional groups such as hydroxyl groups into the products, for example by the use of hydroxyaromtics such as phenol or naphthaol. The alkylated aromatic hydrocarbon products retain the unique features of the alkylating olefinic oligomer and exhibit high viscosity index and low pour point as well as improved thermal and oxidative stability and additive solvency characteristics.
