【Abstract】 Several methods for the determination of phenolic hydroxyl groups in lignins have been compared and discussed in detail. Selective aminolysis (PGC) method is considered to be the best one among the methods studied. PGC method is simple and adaptable for all kinds of lignin. Accurate and reliable results have been obtained in the determination of phenolic hydroxy groups of five species of lignin.更多还原
