This study was conducted to examine the change in the structure of the lignin during liquefaction of kraft pulp lignin in Pinus korainsis and lignin sulfonic acid. The lignin liquefied compounds were extracted with chloroform from aqueous, liquefied lignins. Through the examination by IR, H($^{13}$C) - NMR and GC-MS spectrometers, phenolic compounds such as diguaiacol, acetic acid phenyl ester, phenol, 1-phenyl ethanone were identified with many of unknown phenolic compounds.
