摘要

利用高效液相色谱仪和气相色谱仪分析4种木材（杉木、杨木、马尾松和尾叶桉）中有机挥发物的成分及含量,结果表明:4种木材生材常温均可释放多种醛和萜烯挥发物,其中乙醛的释放量最高;杉木和杨木释放的醛类明显高于马尾松和尾叶桉;杉木释放的萜烯类明显高于其他3种木材;温度由20℃上升到40℃,杉木醛类和萜烯类释放量显著增加。

Abstract

Pure helium gas was applied to wood particles which were placed in a vessel.Aldehyde was collected by a 2.4-DNPH cartridge and analyzed by HPLC.Terpene was collected by an active carbon tube and analyzed by GC-FID.The results showed that aldehydes,such as formaldehyde,acetaldehyde,hexaldehyde,etc,and terpenes,including α-pinene,β-pinene and D-limonene,were released from green wood particles of Chinese Fir,Poplar,Masson’s Pine and Eucalyptus urophylla at 40℃.Acetaldehyde emission was much more than other components.Aldehyde emissions from Chinese Fir and Poplar were higher than from Masson’s Pine and E.urophylla.Terpene emission from Chinese Fir was much more than from the other 3 species of wood.When the temperature rose from 20℃ to 40℃,the volume of aldehyde and terpine emissions from Chinese Fir increased considerably.
