It is difficult to use lignin in any analytical methodology without reducing its considerable polydispersity by fractionation. An ammonium lignosulphonate sample was fractionated using a method of partial solubility in solutions of isopropanol increa

A series of lignin model compounds was subjected to the nucleus exchange reaction (boron trifluoride-phenol at 180°C) to evaluate the application of the procedure to the study of wood and pulp lignin structure. The nucleus exchange reaction of the s

Nitrobenzene oxidation of a series of lignin model compounds with varying aromatic nuclei and sidechain structures, including diphenylmethane compounds, gave benzaldehydes and benzoic acids in a range of yields. The yields were dependent on the struc
