Acetosolv process

Lignin can be extracted from sugar cane bagasse by the acetosolv process with 93% acetic acid, 0.2% HCl, 6.8% water, (w/w) at 109 °C after 3 h pulping treatment. The black liquor is concentrated under reduced pressure and lignin is precipitated in water at 70 °C and purified by dissolution in acetone [148].
