First Claim
Patent Images
1. A process for oxidative dehydrogenation comprising contacting oxygen and organic compounds having 2 to 20 carbon atoms, at least one ##STR2##grouping and boiling point below about 350°
- C, in vapor phase at a temperature of at least about 250°
C in the presence of a catalyst composition containing a lithium ferrite consisting essentially of lithium, iron and oxygen;
lithium, iron oxygen and aluminum or chromium;
or lithium, iron, oxygen, aluminum and chromium the mole ratio of lithium to iron being in the range between 2;
5 to 1;
7, said catalyst composition having a surface area of at least 8.1 m2 /gram.

Abstract
Oxidative dehydrogenation catalysts containing lithium, iron and oxygen, with or without aluminum or chromium, and containing the corresponding ferrite, give superior results and operate at generally lower temperatures than many other ferrite oxidative dehydrogenation catalysts.
