Process And Arrangement for Producing Ethylene Glycol by Paired Electrolysis

Research output: PatentPatent

Abstract

The present invention relates to a process and an arrangement for producing ethylene glycol by paired electrolysis from formaldehyde and methanol. In the process an electrolyte composition comprising aqueous formaldehyde, methanol, at least one salt, and (2,2,6,6-tetramethylpiperidin-1-yl)oxyl is subjected to electrolysis in an undivided electrolytic cell having at least one carbon-based anode and at least one carbon-based cathode. The ethylene glycol is formed by reduction of formaldehyde at said at least one carbon-based cathode. At least part of the formaldehyde is formed by oxidation of methanol at said at least one carbon-based anode.
