Selective Degradation of Lignosulfonate and Lignin with Periodate to 5‐Iodovanillin

Abstract This work represents a new method that uses electrochemically generated periodate to oxidize side‐stream lignins. Using periodate, lignin‐derived product other than vanillin becomes accessible. The development of an eco‐friendly for generating 5‐iodovanillin from lignin is reported and significant interest the wood‐based industry. Wider utilization can substitute fossil‐based chemicals fuels, reduce emission greenhouse gases, facilitate dependence on fossil energy. reaction conditions are easy conduct, modified, no specific setup required. one‐pot cost‐efficient does not use toxic or harmful metals yields more 15 wt% 5‐iodovanillin. 5‐Iodovanillin advanced building block synthesis complex molecules, such as active pharmaceutical ingredients.
