Effect of Heat-treatments on Chemical Properties of Imported Pinus Radiata Wood
Imported Pinus radiata wood samples were treated under different temperatures and the chemical compositions of the samples were analyzed.Results showed that the extract contents of the samples decreased while pH value and buffering capacity of the samples all increased.When heating temperatures were elevated,there were no significant changes of lignin structure between heartwood and sapwood of the samples but more broken linkages(β-O-4’ Aryl ether bond)of the lignin structure units were observed.
