Interaction between Cellulose I and Hemicelluloses Studied by Spectral Fitting of CP/MAS ~(13)C-NMR Spectra

摘要

A review of our work with spectral fitting of CP/MAS ~(13)C-NMR spectra recorded on isolated cellulose I, on a mixtures of cellulose I and xylan and, on kraft pulps is given. The conceptual model for cellulose I used by us is presented. References demonstrating the validity of the spectral fitting model is given. Results from kraft pulps containing hemicelluloses are presented and interpretations discussed based on results obtained from a model system that is a mixture of colloidal sols of isolated cellulose I and xylan. It is concluded that the method used is powerful enough to study, diagnose and monitor interactions between cellulose I and hemicelluloses.
