Abstract:

The main purpose of this study on rosin in Masson pine (Pinus massoniana Lamb.) and its modification is to change the rosin content and its properties so as to eliminate the defects in pinus wood, such as deformation, split and rosin overflow. The properties of modified wood can be suited to the standards of industrial materials. That can be realized by the extraction with chemical reagents or fine solvent and a simple way for industrial production will be able to be obtained from our experiment.

Key words: Pinus massoniana Lamb., Extraction, Deresination, Modification
