摘要
本文介绍利用硝硫混酸常压氧化法，把甜菜废渣制成工业品草酸。通过多次试验，采用正交试验法，选定最佳配方和技术工艺参数，使废渣得到有效而充分的利用，产率达４２％。
This article introduces that using mixed acid of nitric acid and sulfuric acid, beet waste-slag produces industrial product oxalic acid by ordinary pressure hydrocarbonylation. Optimal formulation and technological parameter are chosen by orthogonalazation tests. The waste-slag is used enough and efficiently. Productivity is 42%.
