description At  the present  investigation two  lignins taere prepared for  the comparison of physicochemical properties. One represent«a lignin o'f)tained by evapomtion and the other represents a lignin isolated by pr­ecipitation.For each treatment, the, lignin products was refluxed  by ethanol, hot  water and unrefluxed. The result shows that the yield of lignin mnges from 21,98­38,21  percent, ash content from 29,31­51.,83 percent, silica content from 15,40­27,71   percent moisture content from 3,19­8,09,   methoxyl  content from 0,91­2,64  percent, pH from  4,01­5,09   phenol content from 2,14­7,52   percent, surface area from 29,0­42,0   m1/gr, lignin content from 67,11­80,16  percent and equivalent weight rangesfrom 2512,54­5277,  78.
