Compression wood chemistry

Compression Wood. The formation, structure, and chemistry of compression wood have been given considerable attention (see Reference 30 and references cited therein). Compression wood tissue exhibits both major and subtle differences from normal softwood xylem. These differences (Table II) are either directly or indirectly responsible for any distinguishable changes in the behavior and treat-ability of compression wood versus the behavior generally noted for normal wood. 

The properties of thermally modified wood are highly dependent upon the thermal treatment employed, and it is very important to take these into account when comparing the various treatment methods employed. This chapter examines the effect of the process variables upon the properties of thermally modified wood, and then considers the chemistry of thermal modification. Studies of physical changes are discussed, followed by an overview of the biological properties of thermally modified wood. A short description of some recent literature on the use of thermal treatment combined with compression and on hot oil treatments is also included.
