SYNTHESIS OF ALIPHATIC POLYCARBOXYLIC ACID

摘要

The present invention provides a method for synthesizing an aliphatic polycarboxylic acid, the method comprising the steps of: (a) dehydrating a polyhydroxycarboxlic acid using a rhenium-based catalyst to produce an unsaturated polycarboxylic acid precursor; and (b) performing a hydrogenation reaction on the unsaturated polycarboxylic acid precursor to produce the aliphatic polycarboxylic acid.
