Role in light-induced yellowing

The next phase of research focused on the functional groups in lignin that play a role in light-induced yellowing. Carbonyl and phenolic hydroxyl groups have been studied intensively. [Pg.11]

Tschimer and Dence (32) have demonstrated the role of both the phenolic hydroxyl and carbonyl groups in light-induced yellowing of spruce TMP. For up to two hours irradiation time, complete reduction of carbonyl groups in TMP... [Pg.13]

The role of ketyl radicals derived from the p-0-4 linkage in the light-induced yellowing of mechanical pulps has been established using transient methods... [Pg.83]
