Preparation of alkyl aromatic compounds

摘要

Provided is a process for preparing alkyl aromatic compounds. The process comprises contacting an alkane under dehydrogenation conditions in the presence of a dehydrogenation catalyst, e.g., a pincer iridium catalyst, to form olefins, and then contacting the olefins generated with an aromatic compound under alkylation conditions. Both reactions are conducted in a single reactor, and occur simultaneously.

主权项

1. A process for preparing alkyl aromatics, comprising:
providing in the same reactor at least one alkane, at least one aromatic compound, and a dual catalyst system comprising: a dehydrogenation catalyst comprising a pincer-ligated iridium catalyst, and an alkylation catalyst comprising a zeolite selected from the group consisting of H+SZ25 and a β-zeolite, wherein the dehydrogenation and alkylation reactions occur concurrently within the same reactor to prepare the alkyl aromatics.
