Daftar Isi:
- 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.
