纤维物质水解─—氧化─—水解法制草酸母液的循环利用

The Circulatiue Utihzation of Mother Solution in Pre-paration of Oxalic Acid by Oxidation and Hydrolysis of the Plant Fibre

本文探讨了纤维物质水解—氧化—水解法制草酸母液回用问题。试验结果表明，草酸母液的部分循环利用，不仅可提高草酸的收率，而且降低了硫酸、催化剂的单程消耗，减轻三废处理。

By tests, the circulatiue utihzation of mother solution does not only raise the yield of oxalic acid but also cut down the one way consumption of Sulphuric acid and catalyst, and lighten waste material processing.
