Title: New Technolgy for Preparation of Oxalic Acid from Wheat Straw by Hydrolysis-Oxidation-Hydrolysis
Abstract: The preparation method of oxalic acid from wheat straw by hydrolysis-oxidation-hydrolysis was investigated. The results showed that the optimal condition is as follows: Wheat straw is 50g, sulphuric acid is 70%, soak time≥3h, m(nitric acid) ∶m(wheat straw)=2.1 ∶1.0, V 2O 5-FeCl 3[n(V 2O 5 ∶n(FeCl 3)=1 ∶1] is 0.1g, temperature is 65℃~70℃, and reaction time is 5h. Under the optimal conditions the yield of oxalic acid dihydrate was 75.5%.
