Nitration Process For The Preparation Of 2,6-Dialkylaniline
view source -
US Patent:43407587, Jul 20, 1982
-
Filed:Jul 6, 1981
-
Appl. No.:6/280399
-
Inventors:Seymour J. Lapporte - Orinda CA
David M. Marquis - Lafayette CA -
Assignee:Chevron Research Company - San Francisco CA
-
International Classification:C07C 8511
-
US Classification:564409
-
Abstract:A process for the preparation of 2,6-dialkylaniline which comprises the reaction of 1,3-dialkylbenzene with isobutene in the presence of a hydrogen fluoride catalyst to form 1,3-dialkyl-5-tertiary-butylbenzene, which is subsequently nitrated in the presence of a soluble mercuric salt catalyst to form 2-nitro-1,3-dialkyl-5-tertiary-butylbenzene, which is then catalytically hydrogenated to give 2,6-dialkyl-4-tertiary-butylaniline, followed by pyrolysis in the presence of a heterogeneous acidic catalyst.
