PREPARATION of GLYOXALDEHYDE (GLYOXAL):
The main industrial production methods are gas-phase catalytic oxidation of ethylene glycol and nitric acid oxidation of acetaldehyde.
Gas-phase catalytic oxidation of ethylene glycol.

The catalytic oxidation of ethylene glycol and air in the presence of a copper catalyst at 250-300°C produces Glyoxaldehyde (Glyoxal).
The active component of the catalyst is copper oxide (containing Cu03-8%).

The carrier is alumina or is made of corundum, aluminum sand, impregnated with copper nitrate, and roasted.
The catalyst has a service life of one year and is regenerated by cauterization.

Glyoxaldehyde (Glyoxal) is preheated and gasified and mixed with circulating gas into the catalytic reactor.
The amount of fresh air is controlled to prevent deep oxidation of the glycol.

And a nitrogen gas stream is used to bring in halogen compounds as inhibitors of deep oxidation.
The reaction is carried out at 275°C and 0.74 MPa pressure.

The reaction product is chilled with water.
Absorption and refinement are the finished product.
The one-way conversion of ethylene glycol is 80-85%.

**Acetaldehyde nitric acid oxidation method.
Using copper nitrate as a catalyst.
The liquid phase oxidation is carried out with nitric acid.

Under the condition of stirring and sufficient cooling, acetaldehyde and nitric acid are each prepared into about 50% solution, copper nitrate into 40% solution, and sodium nitrite into 5% solution.

Add a small amount of nitric acid solution and acetaldehyde solution to the reaction pot first.
Then put in the sodium nitrite solution.

Heat slightly until brownish-red gas occurs.
Naturally, raise the temperature to 30°C.

Begin to add a small amount of nitric acid solution and acetaldehyde solution dropwise at the same time.
About 4h add up.

The reaction temperature is controlled at 40-45℃.
The escaped acetaldehyde gas is absorbed by water and added to the reaction pot and the reaction continues for 3h.

The ingredients of acetaldehyde in the reaction are overdosed (by molar ratio, nitric acid: acetic acid = 1:2).
After the reaction, acetaldehyde was recovered by heating to 98°C.
Then activated carbon was added to decolorize, cooled, filtered, and washed with water.

The filtrate and the washings were combined.
Evaporate the organic acid below 70℃ (21.33kPa).

Repeatedly replenish water, and steam again until the acidic cation exchange resin and weakly basic anion exchange resin in the distillate, removing impurities.

The exchange solution and eluate are concentrated to obtain a qualified concentration of Glyoxaldehyde (Glyoxal).
In terms of Glyoxaldehyde (Glyoxal), the yield is about 32%.
