The behaviour of lignin-polysaccharide complex of spruce wood in soda pulping was studied by the characterization of lignin-saccharide fractions isolated from a series of soda pulps. The dioxane pulp lignins contain 8-14% of carbohydrates in which glucose was the predominant component. Its content i

β¦ Synopsis
The origin of the lignin-carbohydrate bonding in a ljgnin-carbohydrate complex isolated by a modified Bj6rkman procedure is discussed. The results obtained from sugar analysis, methylation analysis, deuterium labelling of reducing end groups and gel permeation chromatography are used to evaluate different proposed models for the lignin-carbohydrate bonding.
