INTRODUCTION

The research effort of our group is focused on wood chemistry with emphasis on the fundamental structural and polymer chemistry of wood biopolymers. A major thrust of our effort is focused at developing novel chemicals and materials from a variety of renewable resources. To do this, the fundamental organic chemistry of oxidations as applied to the lignocellulosic substrate is closely examined. In addition, we are developing novel magnetic resonance techniques for probing the structural transformations induced on such polymers during processing. Lignin condensation reactions, lignin-carbohydrate bonds and chromophore formation during chemical pulping are also examined. Other topics include:  Oxygen delignification and oxygen compound bleaching of chemical pulps. Biomimetic catalysis in oxidations of aromatic substrates. Solvents for Green Chemistry. Detection and determination of chromophores induced during yellowing and aging of mechanical and chemical pulps.
