Abstract
Long chain alkyl aromatic compounds are prepared by alkylating an alkylatable aromatic compound with a long chain alkylating agent in the presence of a catalyst comprising an acidic solid material which comprises a Group IVB metal oxide, such as zirconia, modified with an oxyanion of a Group VIB metal, such as tungstate.
Claims20
A process for preparing alkylylatable polynuclear aromatic hydrocarbon compounds which comprises contacting at least one alkylatable polynuclear aromatic hydrocarbon compound with at least one alkylating agent possessing an alkylating aliphatic group having at least six carbon atoms under alkylation reaction conditions and in the presence of an alkylation catalyst to provide an alkylated polynuclear aromatic hydrocarbon product possessing at least one alkyl group derived from said alkylating agent, said catalyst comprising an acidic solid comprising a Group IVB metal oxide modified with an oxyanion of a Group VIB metal.
A process for alkylating an alkylatable polynuclear aromatic hydrocarbon which comprises contacting the alkylatable polynuclear aromatic hydrocarbon with an olefinic alkylating agent having at least about 6 carbon atoms under alkylation reaction conditions and in the presence of an alkylation catalyst comprising an acidic solid comprising a Group IVB metal oxide modified with an oxyanion of a Group VIB metal.
A process for preparing alkylatable polynuclear aromatic hydrocarbon compounds which comprises contacting at least one alkylatable polynuclear aromatic hydrocarbon compound with at least one alkylating agent possessing an alkylating aliphatic group having at least six carbon atoms under alkylation reaction conditions and in the presence of an alkylation catalyst to provide an alkylated polynuclear aromatic hydrocarbon product possessing at least one alkyl group derived from said alkylating agent, said catalyst comprising an acidic solid comprising a Group IVB metal oxide modified with an oxyanion of a Group VIB metal, wherein said contacting is at a temperature in the range of from about 25.degree. to about 200.degree. C.
A process for alkylating naphthalene which comprises contacting the naphthalene with an olefinic alkylating agent having at least about 6 carbon atoms under alkylation reaction conditions and in the presence of an alkylation catalyst comprising an acidic solid comprising a Group IVB metal oxide modified with an oxyanion of a Group VIB metal, wherein naphthylalkane product having a mole ratio of 1-alkylnaphthalene to 2-alkylnaphthalene of greater than about 2 is produced.
