Gluconic acid and sorbitol are obtained simultaneously both with 90% yields by paired electrolysis of glucose, with a Pb sheet cathode and a dimension stable anode (DSA) in a press filtration diaphragm cell. The anolyte is composed from 66.7% glucose and 2% NaBr, and the catholyte from 66.7% glucose and 2.5% Na2SO4, respectively. The electrolysis was performed at the temperature of 60 C, at the current density of 50 mA cm-2, Qr is 110%. At this optimum conditions the current efficiencies for both gluconic acid and sorbitol are higher than 80%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
