SYSTEMS AND PROCESSES FOR PRODUCING ORGANIC ACIDS DIRECT FROM BETA-LACTONES
Provided herein are reactor systems and processes for producing organic acids directly from beta-lactones. Such reactor systems and processes involve the use of a heterogeneous catalyst, such as a zeolite at vapor phase conditions. The reactor systems and processes may use a fixed bed, moving bed or fluidized contacting zone as reactor configurations.
LIGAND-CONTROLLED DIVERGENT DEHYDROGENATIVE REACTIONS OF ALIPHATIC ACIDS
Disclosed herein are palladium-catalyzed dehydrogenation processes of carboxylic acids to make ?, ?-unsaturated carboxylic acids or ?-alkylidene butenolides. The processes allow the chemoselective dehydrogenation of carboxylic acids in the presence of other enolizable functionalities such as ketones, providing reactivity that is inaccessible with existing carbonyl desaturation protocols.
