چکیده
|
Kikar wood (acacia albida) of particle size 0.315-1.00 mm was subjected to acetosolv and organosolv pulping catalyzed by strong acid like hcl. the selective condition for pulping is 95%,0.25% catalyst (hcl) solid/liquor ratio (s/l) 1:12.5 for 180 mins,for acetic acid,80%,0.2% catalyst (hcl),s/l 1:12.5 for 120 min,for formic acid,85%,0.2% catalyst (hcl),s/l 1:12.5 for 180 min for propionic acid,giving residues impurities but the a-cellulose and klason lignin 58.5% and 24.1% in kikar wood. the optimum delignification was achieved by the acetic acid as compared to other organic acids.
