text: 31P NMR spectra of the reference lignin, Lign EP , and aminolysis lignin derivative that show the characteristic distribution of the primary and secondary aliphatic alcohols after the epoxidation and aminolysis reactions
text: Figure 1 reports the 31P NMR spectra of the reference lignin, Lign EP , and aminolysis lignin derivative after the reaction with 2-chloro-1,3,2-dioxaphospholane, which was used as a derivatizing agent to better resolve the primary and secondary aliphatic hydroxyls.
