摘　　要：研究了用氧化法制备草酸中产生的富二氧化氮气尾气再次氧化淀粉制备草酸的工艺，找出了最佳工艺条件，草酸收率为５５％。This paper is concerned with the technique of preparimg oxalic acid by oxidizing starch with the exhaust gas enriched nitrogen dioxide which is produced in the process of preparing oxalic acid by oxidizing starch with nitric acid. And the optium operation is gained, the yield of oxilic acid is 55 %. The cost is lowered and exhaust gas is decreased.
