Fractionation of Alcell lignin by sequential solvent extraction

A prototype solvolytic lignin has been fractionated into three fractions by successive extraction with organic solvents of increasing hydrogen-bonding capacity. A comparison between the fractions and the starting lignin has been made in terms of methoxyl group content, fractionation yields, molecula...
