Abstract
Cyclohexenyl and alkenyl aromatic compounds, such as cyclohexene and styrene, are prepared by a process comprising contacting a corresponding cyclohexyl or alkyl aromatic carboxylic acid, such as cyclohexyl carboxylic acid or 2-phenyl propionic acid, with a decarboxylation catalyst of the formula M.sub.a M'.sub.b O.sub.x where m is copper or a combination of copper and molybdenum, and M' is at least one promoter element, such as a Group IA element.
Claims7
A process for preparing a cyclohexenyl compound, the process comprising contacting a corresponding cyclohexyl carboxylic acid with a decarboxylation catalyst of the formula:
- M.sub.a M'.sub.b O.sub.x
- where
- M is a combination of copper and molybdenum;
- M' is at least one of sodium, potassium, cesium, tin and bismuth;
- a is a number of about 0.1 to 1;
- b is a number of about 0.01 to 0.5 and
- x is the number of oxygen atoms determined by the valence requirement of the other elements present.
