NMR study of aqueous tetraalkylammonium silicates
(1994)
Silicon-29 nuclear magnetic resonance (NMR) spectroscopy has been
used to investigate the equilibrium distribution and kinetics of silicate oligomers
in aqueous tetraalkylammonium silicate solutions. Certain tetraalkyl ...
NMR studies of lignin models, derivatives and bleaching effluents
(1995)
NMR problems related to assignment techniques and relaxation restrict the use of
NMR in the structural analysis of lignin. These problems have been addressed in three
practical studies in this thesis involving a lignin ...
