Filed:

Dec 12, 1977

Appl. No.:

5/859896

Inventors:

William E. Slinkard - Corpus Christi TX
Anthony B. Baylis - Berkeley Heights NJ
Michael P. Hughes - Odessa TX

Assignee:

Celanese Corporation - New York NY

International Classification:

C07C 5120
C07C 5308

US Classification:

562549

Abstract:

The present invention provides an unsupported catalyst with superior crush strength for use in a vapor phase reaction for the high yield conversion of lower aliphatic hydrocarbons such as n-butane to corresponding monocarboxylic acids used as acetic acid. The catalyst is prepared by the reduction of a vanadium oxide containing chromium catalyst.

Michael P. Hughes - Odessa TX

Assignee:

Celanese Corporation - New York NY

International Classification:

C07C 5120
C07C 5308

US Classification:

562549

Abstract:

The present invention provides a highly efficient process for use in the high pressure catalytic vapor phase reaction for the high yield conversion of lower aliphatic hydrocarbons such as n-butane to corresponding monocarboxylic acids such as acetic acid. The oxidation reaction takes place under hydrocarbon rich conditions. The increased efficiency in this process is realized by the judicious use of steam and the catalyst systems set forth in the instant invention.
