摘要
在强酸性环境下,甲醇可以与氯酸钠发生氧化还原反应,氯酸钠由此被还原而产生二氧化氯,人们将这种二氧化氯制备方法称之为甲醇法。纸浆漂白甲醇法二氧化氯制备系统国产化已经实现,目前已成功运行多套系统。本文分析了影响纸浆漂白甲醇法二氧化氯系统工艺转化率的相关因素,并结合生产实际提出了相应的改进措施。
Methanol can make oxidation-reduction reaction with sodium chlorate under strong acid situation. Sodium chlorate is restored to make chlorine dioxide, which is called methanol method to prepare chlorine dioxide. The methanol method for chlorine dioxide preparation has been localized successfully, which has been well proven in many projects in bleaching plant in pulp industry. In this article were analyzed the relating factors of conversion rate of chlorine dioxide which is used in pulp bleaching process, and was put forward the corresponding improving measures combined with the production practice.
