| Abstract: | Using different catalysts, glyoxylic acid was produced through oxidizing glyoxal with nitric acid. The mechanism of catalysis was discussed, and the effects of different catalysts on the yield of glyoxylic acid were investigated. The experimental results showed that the yields of glyoxylic acid were 73.9%, 84.6%, 80.2% and 78.2%, by using catalysts based on sodium nitrite, hydrochloric acid and sodium nitrite, cerium dioxide and sodium nitrite, and cupric nitrate and sodium nitrite correspondingly. |
