Electroreduction of Maleic Anhvdride Studied by Using Ion Chromatography

The main species of succinic acid system synthesized by Maleic acid Galvanostatic synthesis which are succinic acid and maleic acid were analyzed qualitatively and definite qualitatively by Ion chromatography conductivity detection success- fully which can realize the real time analysis speedily and accurately in the process of electronic synthesis of succinic acid. The conclusion of the research indicated that the Ion chromatography conductivity detection has many advantages such as sensitive- ness, speed, with simple facilities and high selection in the detection process of succinic acid and maleic acid. The using of surface alloy/stainless steel as cathode material in electronic deoxidizing of maleic acid manifests high electronic catalysis living and good selection of succinic acid, and under the condition of 31.1mA·cm-2, galvanostatic current 1.56h, the current efficient and the amount of succinic acid are much higher.
