摘要: Looking for ways to improve the catalytic activity of a Ni anode during oxidation alcohols in basic medium, we tested action amino compounds as Ni-complexing agents. We have discovered significant increase effective rate corresponding carboxylic acids presence compounds. The activating effect (AEAC) became basis industrial method produce acid diaceton-2-keto-L-gulonic (DAG), an intermediate synthesis vitamin C. DAG electrosynthesis at stainless steel (StS) anodes with capacity 1,500 t/year/production line was developed. application electrochemical allowed drastically reducing wastes and resulted economy effects. Operation 10 years showed good corrosion resistance, stability, safety process. There are other possible AEAC applications, particular, increasing sensitivity ROH sensors. possibility using improving efficiency direct alcohol fuel cells (DAFC) Ni-containing systems is also discussed.
