Glyoxal 40% is typically produce method is the oxidation of ethylene glycol. The most common method involves the oxidation of ethylene glycol using a catalyst, such as silver or copper.
In China, all glyoxal 40% producing method from one state-owned enterprise in Shanghai. Since it closes, their technical personnel, or producing managers establish their own factory or enter university. Our technical advisor was QC manager in such Shanghai plant and doctoral supervisor in Zhejiang University. The present glyoxal 40% producing method is almost same, whose main difference are only on some details like dealdehyde or catalyzer. Most of Glyoxal 40% equipment is outdoor, some key technologies can be identified according to the size of the equipment.
Glyoxal 40% plant public photos.
The produce line for formaldehyde begins since 1995. When produce formalhyde , it has one mixed gas almost same component with natural gas. Such mix gas is a material in the oxidation of ethylene glycol.
Zhangjiagang Free Trade Zone is the first largest place to import ethylene glycol. It also has many large storage tanks. It is around 300KM to our plant.
It has four storage tanks in work shop 1, each one is 150m³. Except for using glyoxylic acid 50% producing, it has at least 600MT Glyoxal 40% on stock.
Glyoxal 40% warehouse is mainly for empty drums or IBC drum. We can also offer packing as clients requirements.
Glyoxal 40% aqueous solution flows via pipeline and is filled in drums. It weights manually and contols average error within 0.5kg.
