Acetic acidlignin (al) from acetic acid pulping was isolated and purified. Chemical structure and molecular weight of al were studied with infrared spectroscopy and GPC determination.
The water insoluble precipitate (acetic acidlignin, AcL) had a low weight-average molecular weight range from 341 to 253 (Mw) and a narrow molecular weight distribution from 1.1 to 1.2.
