摘要: The difference in decomposition behavior of lignin from Japanese cedar (Cryptomeria japonica) as softwood and beech (Fagus crenata) hardwood treated by hot-compressed water was investigated. obtained residual then evaluated the alkaline nitrobenzene oxidation analysis, relative proportion ether type linkages had decreased for both species treatment prolonged. Furthermore, microscopic observation indicated that tracheid cell walls removed to a greater extent than middle lamella cedar. Similarly beech, fiber more extensively, with remaining after two-step treatment. Such supported result methoxyl content analysis per C9 unit lignin. Based on these lines evidence, must be rich condensed type, differences between can attributed intrinsic characteristics original its topochemistry woods.
