Kinetics of Eucalypt Lignosulfonate Oxidation to Aromatic Aldehydes by Oxygen i...
Santos, Sonia G.; Marques, Ana P.; Lima, Diana L. D.; Evtuguin, Dmitry V.; Esteves, Valdemar I.The oxidation kinetics of lignosulfonates (LS) from acidic magnesium-based sulfite pulping of Eucalyptus globulus wood with oxygen under alkaline conditions was studied. The analysis of oxidation products in the reaction system O(2)/NaOH revealed a predominance of aromatic aldehydes (vanillin and syringic aldehyde) though small amounts of vanillic and syringic acids and acetophenone/phenylacetaldehyde derivativ...
