Copper Acetate is a metabolic substance of plants, which is widely distributed in green plants, small animals and bacteria, and fully exerts different functions in different organisms. Studies have found that more than one hundred kinds of green plants contain copper acetate, especially green plants such as broccoli, shepherd's purse, cabbage, purslane, yam, sweet potato, and pistacia chinensis, because copper acetate can reduce the utilization rate of mineral elements in microorganisms. It is very easy for the body to produce copper and calcium acetate with sodium ions to cause kidney tuberculosis. Therefore, copper acetate is generally considered to be an antagonist for the digestion and absorption of mineral elements.

The key to the industrial production methods are: sodium formate method, air oxidation method, carbonyl formation method, ethylene glycol air oxidation method, pe air oxidation method, carbon monoxide coupling method.

1. Sodium formate method

After cleaning, the carbon monoxide chemically reacts with sodium hydroxide solution under pressure to convert it to sodium formate, which is then converted to sodium copper acetate by high-temperature dehydrogenation. The copper sodium acetate is then leaded (or thickened), alkalized, crystallized and removed Dry to dry and other technological processes to obtain the finished product copper acetate. The working pressure of carbon monoxide and sodium hydroxide solution is generally 1.8-2.0MPa. The dehydrogenation temperature is 400 ° C.

2. Air oxidation method

With tapioca starch or fructose hydrolysate as raw material, in the presence of alum catalyst, redox reaction is carried out with sodium cyanide-copper acetate to obtain copper acetate. Nitrogen oxide in the organic waste gas is sent to the desulfurization tower for environmentally friendly renewable resources for recovery and conversion into dilute nitric acid.

3, carbonyl formation method

Carbon monoxide is purified to more than 90%. In the presence of a palladium catalyst, it reacts with butanol to produce a carbonylation chemical reaction, which is converted into copper dibutyl acetate, and then copper acetate is obtained according to the hydrolysis reaction. This method is divided into high-performance liquid phase method and liquid phase method. Two kinds, the liquid phase chemical reaction standard is lower, the chemical reaction working pressure is 300-405kPa. The high-pressure liquid phase chemical reaction working pressure is 13.0-15.0MPa.

4. Ethylene glycol air oxidation method

Is obtained by oxidation with ethylene glycol as raw material in the presence of sodium cyanide and copper acetate.

5. The whole process of air oxidation by pe air oxidation method is carried out in two steps

Air oxidized with sodium cyanide to convert pe to α-nitrolactic acid bacteria; then further catalyze the reaction to obtain copper acetate. In the second step, mixed acid can also be used as a reducing agent. pe air oxidation method manufactures industrial-grade copper acetate dihydrate chemical substances, and the total finished product rate in terms of pe exceeds 90%.

Copper acetate is packed in the inner plastic film and outer fabric fiber bag. The temperature should not be higher than 40oC during storage and transportation. It is waterproof and rainproof. It is separated from alkaline substances, avoids contact with food materials, and prevents direct contact with the skin during transportation .
