WebSimilarly, in the ethanolysis of glucose, formation of ethyl-D-glucopyranoside (EDGP) results in a slow conversion to product EL. The review, therefore, focuses on highlighting the importance of catalyst structure, acidity and reaction mechanism and the role of key intermediates in the production of EL from biorenewable resources.
