Lignin And Lignans: Advances In Chemistry

Over the past four decades, there has been immense progress in every area of lignin science, ranging from the enzymology of lignin biodegradation, to the delignification of wood fiber during pulping and bleaching, to advances in spectroscopy. Lignin and Lignans: Advances in Chemistry captures the developments that have been achieved by world-class scientists in the most critical aspects of this burgeoning field.

The authors discuss polymer properties related to thermal stability and molecular motion of lignin in the solid state. They describe applications of electronic structure calculations to the chemistry of lignin, and they explore lignin reactions that occur during the chemical pulping of wood by soda, kraft, AQ, and polysulfide processes.

Cyril Heitner retired from Pulp and Paper Research Institute of Canada (now FPInnovations) after a 36-year career. He received his BSc in chemistry from Sir George Williams University in 1963, his MSc in physical organic chemistry from Dalhousie University in 1966, and his PhD in organic photochemistry from McGill University in 1971. Dr. Heitner has made significant scientific contributions in the area of chromophore chemistry of lignin-containing pulp and paper. This research has led to the development of a yellowing-inhibitor system that is close to commercial development.

Donald Dimmel, formerly of the Institute of Paper Science and Technology in Atlanta, has been retired from professional life since 2002 and lives in Prescott, Arizona. He received a BS in chemistry from the University of Minnesota in 1962 and a PhD in organic chemistry from Purdue University in 1966. He has authored 100 refereed technical publications and patents. His research interests concerned reducing the energy and environmental impact associated with producing paper pulps from wood. Much of his research focused on developing a better understanding of the chemistry of lignin removal and carbohydrate degradation reactions that occur during pulping and bleaching. 041b061a72
