목재의 용액화 (Ⅱ) : 액화목재의 성분분석 Analysis of Liquefied Wood Components
도금현,공영토 한국목재공학회 1995 목재공학 Vol.23 No.2
This research was carried out to investigate the methods of liquefaction with Pinus koraiensis, and chemical components of the liquefied wood by FT-IR analysis and pyrolysis-GC/MS. Acetylated wood powder was liquefied above 90% in phenol or m-cresol when treated at about 150℃ for 30min., using some catalysts. Untreated wood powder was liquefied above 90% in phenol or m-cresol when treated at about 200℃ for 60min., using some catalsts. The results of FTIR analysis, carbohydrates were terribly disintegrated, the other side lignin peaks were occurred in Liquefied wood, particulary. The results of pyrolysis-GC/MS, the liquefied wood have clear four peaks, phenol, guaiacol, o-cresol and m-/p-cresol, due to degradation of lignin, particulary.
