Source sentences:
text: The consistently stable thermal behavior of the kraft lignin whose phenolic hydroxyl groups were fully methylated paved the way in posing the question: would this material be stable if repeatedly subjected to heating and cooling cycles?
text: Therefore, the hydroxyl groups are acetylated and carboxylic acid groups are methylated prior to SEC analysis to exclude possible noncovalent interactions, such as hydrogen bonding and electrostatic repulsion, from the lignin.
text: In concurrent work dedicated to simulating the final step in the process of lignin biosynthesis in vitro, it has been observed that the monolignol coniferyl alcohol can undergo dehydropolymerization on dissolved macromolecular lignin templates in just the same way regardless of whether the phenolic hydroxyl groups on the latter have been methylated.
