39593371, May 25, 1976

Filed:

Apr 15, 1975

Appl. No.:

5/568360

Inventors:

Ronald D. Bushick - Glen Mills PA
Howard P. Angstadt - Media PA

Assignee:

Sun Ventures, Inc. - Philadelphia PA

International Classification:

C07C12014

US Classification:

260465C

Abstract:

An ammoxidation process for preparing nitriles from m- and p-xylene whereby the formation of carbon oxides is held to a minimum which comprises reacting the xylene and ammonia at a temperature of from about 375. degree. C. to about 500. degree. C. and in the presence of added oxygen, the molar ratio of ammonia to xylene being about 3:1 or less, the molar ratio of oxygen to xylene being about 3:1 or less, the volume percent concentration of the feed being preferably about 3% to 10% hydrocarbon, 7% to 20% ammonia, and 10% to 20% oxygen, and the catalyst for said reaction comprising at least about 1 to 10% by weight of a vanadium bronze supported on. alpha. -alumina.

Assignee:

Sun Ventures, Inc. - Radnor PA

International Classification:

C07C12014

US Classification:

260465C

Abstract:

In an ammoxidation process where reactant gases comprised of a lower alkyl-substituted aromatic hydrocarbon, oxygen, and ammonia are passed over an ammoxidation catalyst in a fixed or fluidized bed system, the improvement of reducing combustion of hydrocarbon and ammonia and achieving a more favorable product distribution by distributing a stream containing reactant oxygen throughout the catalyst bed.

International Classification:

C07C12014

US Classification:

260465C

Abstract:

An ammoxidation process for the preparation of nitriles by reaction of m- or p-xylene with ammonia and oxygen using as catalyst an. alpha. -alumina supported vanadiumalkali metal bronze promoted with niobium, whereby a high proportion of dinitrile product is obtained.
