摘要

A novel method that permits the quantitative detection and classification of various carbonyl groups in lignins has been developed. The proposed method was optimized with the quantitative trifluoromethylation of a series of carbonyl-containing lignin-like model compounds. This effort was followed by 19F NMR spectral analyses of the resulting fluorine derivatives allowing for a thorough understanding of their structure/19F chemical shift ...
