Conversion of Lignocellulose Studied by Nuclear Magnetic Resonance

doi:10.11938/cjmr20202850

Abstract

Abstract:

Nuclear magnetic resonance (NMR) is an important characterization method for the depolymerization of lignocellulosic biomass and its structure evolution analysis. The accurate NMR analysis facilitates the selective transformation of different biomass components. In this review, the principles of NMR are presented. Four types of NMR experimental methods, including ¹H NMR, ¹³C NMR, ³¹P NMR and 2D HSQC, and their applications in the structure elucidation, qualitative and quantitative analysis of products, reaction path and catalytic depolymerization mechanism of lignocellulose are mainly introduced. Finally, the main problems and perspectives of NMR method in valorization of lignocellulosic biomass are discussed.

Key words: lignocellulose, ¹H NMR, ¹³C NMR, ³¹P NMR, 2D HSQC
