Liquefaction of Wood and It's Application for Adhesives - Acid-Catalyzed Liquefaction of Wood with Phenol -

목재의 용액화와 접착제에의 응용 - 산촉매하에서 페놀에 의한 목재의 용액화 -

Acid-catalysts were used to accelerate the liquefaction of wood with phenol. Sulfuric acid was quite excellent as a acid-catalyst of liquefaction of wood. It's proper dose was 3% of oven-dried weight of wood to get the 10% of target degree of residue, when the reaction time was 2 hours. The liquefaction of wood catalyzed with sulfuric acid was easily carried out at low temperature of 140$^{\circ}C$, but the degrees of residue decreased gradually with the increase of reaction temperature. The behaviors of liquefaction of oak and radiata pine were nearly same.
