摘　　要：植物纤维素原料中 4 O 甲基 葡萄糖醛酸在高温和碱性介质下会转变为己烯糖醛酸侧基。麦草碱法纸浆中己烯糖醛酸的含量比木材 (特别是阔叶木 )低得多 ,只有 10 μmol/During kraft pulping (high temperature and alkaline condition),a major part of the 4 Omethyglucuronic acid groups of xylans are converted to be 4 deoxy β L threo hex 4 enopyranosyluronic (expressed as HuA). There is much lower content of hexenuronic acid groups in wheat straw pulp compared to the wood pulp. It has only about 10 μmol/g.
