Abstract: This disclosure concerns a process for preparing a synthetic hydrocarbon lubricant composition, said composition consisting essentially of a major amount of di-long-chain alkyl monocyclic aromatic hydrocarbons and a minor amount of trialkyl-substituted tetrahydronaphthalenes. The process comprises (a) alkylating an admixture of a major amount of mono-long chain alkyl monocyclic aromatic hydrocarbons and a minor amount of alkyl-substituted tetrahydronaphthalenes with linear mono-olefins containing six to 18 carbon atoms, using aluminum chloride or aluminum bromide as the catalyst, under severe reaction conditions and (b) recovering the desired product. In both the mono-long-chain alkyl aromatic and di-long-chain alkyl aromatic hydrocarbons, the long-chain alkyl groups are linear and contain six to 18 carbon atoms while the aromatic moiety is phenyl, tolyl, or xylyl.
