The preparation and properties of wood vinegar obtained by pyrolysis of fir sawdust under different temperatures were studied. The results showed that the most important pyrolysis phase of fir sawdust was 150-250 ℃, which obtained the most of wood vinegar and organic compounds. Under this pyrolysis phase, the highest yield of organic compound was phenols, and followed with acids. The relative content of organic compounds in wood vinegar was increased with the increasing of prolysis temperature, which is up to 48% after 150 ℃. The relative content for each kinds of organic compounds was different under various temperature range, the highest relative content of acids was in 0-150 ℃, while phenols and ketones in 250-350 ℃, and aldehydes in 150-250 ℃.

Key words: fir sawdust, wood vinegar, pyrolysis, organic component
