In this study, the investigation was made to determine the content, chemical and physical properties, calorific value, and chemical composition of benzene extracts from paraquat treated wood.
The main results are as follows :
paraquat treated Japanese red pine (Pinus densiflora S. et Z.) produced much extracts and calorfic value became higher.
1) On the section which did not over the height of 150 cm above lower treated point, the treatment of paraquat doubled or trebled the yield of benzene extracts as compared with those in control.
2) The yield of benzene extracts was proved that the treatment of paraquat was more effective at height of 150 cm below from lower treated point.
3) Most of the resin which was increased by treatment of the paraquat was composed of the fatty acids.
4) The linear relation was obtained between amount of the resin acid of benzene extracts and the calorific value.
5) The calorific value showed decrease tendency contrary to an increase of oxygen content and O/C ratio of extracts.
