Analysis of chemical properties of thermally treated Pinus roxburghii Sargent wood

Effects of thermal modification were determined relative to chemical parameters Pinus roxburghii. Thermal wood was carried out at 80, 120, 160, and 200 °C for 2, 4, 6 h. The properties different temperatures heating time. All similar except cold water soluble extractives. Among the studied, maximum mean value extractives (8.20%), hot (12.7%), holocellulose content (71.8%), ash (1.46%) recorded 120 °C, whereas values alcohol benzene (13.9%) lignin (33.7%) observed °C. minimum (5.82%), (9.27%), (65.8%), (1.03%) found be while highest 12.2% (control) (28.0%) 80
