The pulp from Korean mixed oaks were prepared by LAS (Low temperature, Atmospheric pressure, and Short reaction time) pulping method with different temperature and reaction. The pulp prepared under low cooking temperature had a high residual lignin content spite of increasing cooking time. However, as the cooking temperature increased, the lignin in the wood was easily removed and the yield of pulp increased and the residual lignin content decreased. The peak intensities derived from hemicellulose and lignin, which have been confirmed from wood chips, are gradually weaker in response to pulping. Peak regions representing cellulose were strongly confirmed from IR data of pulp prepared at more than 110℃. It can be concluded that pulping of Korean mixed oak was suitable for 60 minutes at 110℃. It was predicted that the possibility of using the LAS pulp as a raw material for papermaking was high because the LAS pulp showed the same fiber characteristics as KP. LAS pulp showed higher glucose content than wood chip, many hemicellulose was eluted by acid catalyst and showed low xylose content. The reason why the syringaldehyde ratio of LAS pulp decreased compared to wood chips was that a large amount of lignin was condensed by cooking reaction.
