钒二取代磷钨酸在硝酸氧化淀粉制草酸中的催化作用

Catalytic Behaviour of Nitric Acid in Making Oxalic Acid with Oxidative Amylum on V-substituted Phosphotungstic Acid

本文研究了钒二取代磷钨酸对淀粉制草酸产率的影响.实验表明,该催化剂选择性好,用量小,草酸产率高。

In this paper,the effect on productivity of making oxalic acid with amylum Ⅴ-substituted phosphotungrtic acid is studied. The experiment shows that, as the catalyst,the vanadium has good selectivity and can improve the productivity of oxalic acid.
