Abstract: In order to determine the technological conditions of refining wood vinegar used as acidic additives in beverage, feed of domestic animals and drinking water, the change of organic components in the refining process of wood vinegar was investigated with GC/MS in detail.Phenol, which is harmful to human body and domestic animals, was analytically traced as representative component.Result showed that through combinated application of several simple and typical refining unit operations, phenol and other hard removable harmful components could be removed.Through refining process, phenol concentration was reduced to undetectable degree from 836 mg/L of the original wood vinegar.

Key words: wood vinegar, GC/MS, phenol
