Characterization of Kraft Lignin Prepared from Mixed Hardwoods by 2D HMQC and 31P NMR Analyses

Characterization of Kraft Lignin Prepared from Mixed Hardwoods by 2D HMQC and 31P NMR Analyses

This study was conducted to determine the lignin substructures, hydroxyl (phenolic + aliphatic) contents, and carboxyl contents in kraft lignin (KL) prepared from mixed hardwoods by using 2D Heteronuclear Multiple Quantum Coherence Nuclear Magnetic Resonance (HMQC NMR) and 31P NMR techniques. Based...
