摘　　要：用过氧化氢和氨水对麦草碱木质素进行氧化氨解 ,分析了氨水用量、过氧化氢用量、反应温度、时间和木质素浓度对产物总氮及有效氮含量的影响。结果表明 ,过氧化氢用量对工业木质素的氧化氨解反应的影响最大 。Wheat straw alkaline lignin was oxiammonolyzed using hydroperoxide and ammonia. The effects of ammonia dosage, hydroperxide dosage, reaction time and temperature and concentration of lignin on the contents of total nitrogen and hydrolyzable nitrogen were analyzed. The results show that the dosage of hydroperoxide plays an important role on oxiammonolysis reaction of technical alkaline lignin, however, the effect of lignin concentration is little.
