摘要
采用选择性水解和紫外分光光度法测定了湿地松、加勒比松、尾叶按和雷林# 1桉硫酸盐浆中的己烯糖醛酸含量 ,探讨了己烯糖醛酸对纸浆卡伯值、粘度、白度及ECF漂白的影响。
A major part of 4 O methyl glucuronic acid groups in xylan sidechain are converted to 4 deoxy hexa 4 enuronic acid groups(HexA)in kraft pulping.HexA contents in kraft pulps of P elliottii,P caribaea,E urophylla and E Leizhou No 1 have been determined by selective hydrolysis and UV spectrophotometry.Effects of HexA on the pulp Kappa number and ECF bleaching have been studied.
