Verfahren zur Herstellung von Glyoxylsaeure
Glyoxylic acid is prepared by oxidizing ethylene in the presence of a palladium salt with nitric acid maintained at a concentration of 10 to 16% base on the reaction medium. From 1 to 5% of nitrogen peroxide, based on the weight of the nitric acid solution, may be present as an initiator, and pallad...

| Zusammenfassung: | Glyoxylic acid is prepared by oxidizing ethylene in the presence of a palladium salt with nitric acid maintained at a concentration of 10 to 16% base on the reaction medium. From 1 to 5% of nitrogen peroxide, based on the weight of the nitric acid solution, may be present as an initiator, and palladium chloride, sulphate, nitrate, phosphate or oxalate may be used or metallic palladium or oxide which yield palladium nitrate in the reaction may be used. |
