    Abstract: THIS DISCLOSURE CONCERNS THE REPARATION OF A HYDROCARBON COMPOSITION CONTAINING A MAJOR AMOUNT OF ALKYL AROMATIC COMPOUNDS HAVING TWO LONG-CHAIN ALKYL GROUPS AND A MINOR AMOUNT OF ALKYL-SUBSTITUTED TETRAHYDRONAPHTHALENES BY THE DISPORTIONATION OF AROMATIC COMPOUNDS HAVING ONE LONG-CHAIN ALKYL GROUP USING ALUMINUM CHLORIDE OR ALUMINUM BROMIDE AS THE CATALYST. THE TERM "LONG-CHAIN REFERS TO LINEAR ALKYL GROUPS CONTAINING FROM ABOUT 8 TO ABOUT 18, PREFERABLY FROM ABOUT 10 TO ABOUT 16, CARBON ATOMS. THE HYDROCARBON COMPOSITION (I.E. DISPROPORTIONATED PRODUCT) IS USEFUL AS A SULFONATION FEEDSTOCK AND AS A LUBRICANT.

    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.
