The chlorine concentrations of lignin in the cell corner middle lamella and secondary wall of chlorinated spruce tracheids and birch fibers were determined by the TEM-EDXA technique. In both woods, the chlorine reacted very rapidly with lignin, but the extent of the reaction was greater in the secondary wall than in the cell corner middle lamella. The chlorolignin in the cell corner middle lamella was more easily removed by alkali extraction than that in the secondary wall for both spruce tracheids and birch fibers. 19 references, 1 figure, 6 tables.
