摘要
作者通过实验,探讨了淀粉氧化法制草酸的反应温度及控制,硝硫混酸比例,硝酸投入量,NO_x回收利用,以及母液循环方式等几个方面的最佳选择。研究成果用于生产实践,取得了较好效果。
Reaction temperature and its controlthe mixing ratio of nitric acid to sulfuric acid,amount of HNO_3,the recovery and utilization of NO_x,the recycling of mother liquor.are optimized in the preparation of oxalic acid from starch. Findings in this work have found satisfactory application in commercial production.
