过氧化物-氨溶液对松木的脱木素作用

Peroxide-Ammonin Delignification of Pine Wood

介绍了用过氧化物．氨溶液对松木进行氧化脱木素，研制出的一种新型生产纸浆和舍氮有机肥料方法，用过氧化氢（H2O2）-氨（NH3）溶液对松木进行脱木素，3％-9％H2O2和10％NH，溶液蒸煮松木，结果纸浆得率54．6％，纸浆中残留木素含量1．1％。通过动力学一级反应方程式讨论了H2O2-氨溶液对松木的脱木素作用是令人满意的。

This paper discusses oxidative delignification of pine wood by hydrogen peroxide in agueous ammonia A new method for produeing pulp and N-Containing organic fertilizers was developed, hydrogen peroxide（ 3 - 9% ）in aqueous ammonia delignified pine wood to produce pulp in yields 54.6% with a residual lignin 1.1%. The process of pine wood delignification by hydrogen peroxide in agueous ammonia was described satisfactorily by a first -order kinetic eguation.
