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.
