Decarboxylation, as an important chemical reaction, was widely applied in chemical, biological, pharmaceutical and pabular fields. Currently, thermochemical and acid-, base-catalyzed decarboxylation, these raditional technologies, were usually employed by intrustry, which have the problems of low reaction efficiency and environment pollution, respectively. High temperature liquid water has the ability to decarboxylate some small molecular carboxylic acids without catalysis and decarboxylate the fatty acids ...
