SYNOPSISThe model compound used in this study, for hardwood kraft lignin, 3,5-dimethoxy-4-hydroxyphenyl ethane, was successfully hydroxymethylated at the position metu to the aromatic hydroxy group. The consequent expectation that kraft hardwood lignin syringyl units can, under optimum conditions, also be hydroxymethylated to a substantial extent was confirmed in the present work and made it possible to cross-link the kraft hardwood lignin to yield polymeric products that could be used as adhesives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
