Physico-chemical properties of lignin sulfonates.
Lignin sulfonates were separated into eight fractions with molecular weights ranging from 3,700 to 58,000 by means of fractional dialysis and ultrafiltration. All fractions have similar ultraviolet absorption spectra. Their methoxyl contents and neutralization equivalent weights increase with increa...
