To analyze chemical compositions of softwood vinegar prepared with continuous carbonized kiln, the chemical compositions were analyzed by GC-MS spectrometry. The results were summarized as follow : 1. The amounts of methylalcohol and acetic acid and of vinegar were 0.12% and 0.8% respectively, and acidity was 0.85 2. Perfume components of vinegar were frufual, 5-meayl-2-furancarboxyaldehyde, 2,3-pentanedione, 2-butanol, 2,3-dihydrofuran, 1-(2-furanyl)-etanone, benzaldehyde, 2-furan carboxyaldehyde and acetic acid. 3 Vinegar prepared from softwood, so that murk amount of guaiacyl compound and phenol derivetives are produced from lignin and extractives was analγzed. 4 The yield of 4-methyl-di-tert-butylphenol was the highest in the nutural and carbonyl and acetic acid in the acid fractions, 3-ethylpentane in the basic fraction, and guaiacol in the phenolic fraction.
