Electroreduction of divanillin to polyvanillin in an electrochemical flow reactor.

ABSTRACT: The electrochemical conversion of biobased intermediates offers an attractive and sustainable process for the production of green chemicals. One promising synthesis route is the production of the total vanillin-based polymer polyvanillin, which can be produced by electrochemical pinacolization of divanillin (5-5´bisvanillyl). Divanillin can be easily enzymatically generated from vanillin, a renewable intermediate accessible from lignin on an industrial scale. This study investigates systematically the electrochemical production of polyvanillin in a divided plane parallel flow reactor in recirculation mode. Several analytic methods, such as online UV-VIS spectroscopy, size exclusion chromatography (SEC), 2D-NMR (HSQC, ¹³C/¹H), TGA and DSC were used to monitor the react
