Adipic acid, also known as fatty acid, is an important organic dicarboxylic acid, white crystal, with the smell of burnt bones.Soluble in water, soluble in alcohol, ether and other organic solvents.It can produce salt reaction, esterification reaction, amide reaction and so on, and can be condensed into polymer and so on with binary amine or dibasic alcohol.Adipic acid is industry has important significance of binary carboxylic acid, in chemical industry, medicine production, organic synthesis, play an important role in such aspects as lubricant manufacturing and production in all binary carboxylic acid in the second place.
1. Mainly used as the material of nylon 66 and engineering plastics, also used in the production of various kinds of ester products.
2. used as the material of polyurethane elastomer, all kinds of food and beverage acidulant, its role is sometimes better than citric acid and tartaric acid.
3. It is also a raw material for medicine, yeast extract, insecticides, adhesives, synthetic leather, synthetic dyes and spices.
4. The acidity of adipate is mild and persistent, and the pH value changes less in the larger concentration range, which is a better pH regulator.
5. Gb2760-2007 regulation, this product solid beverage, its maximum usage is 0.01g/kg;
6. It can also be used for jelly and jelly powder. The maximum use of jelly is 0.01g/kg.
7. When used for jelly powder, it can be used to increase the amount of punch.
It can stimulate the eyes, skin, mucous membrane and upper respiratory tract.
No occupational injuries were reported in industrial use.
The environmental impact:
Acute toxicity: LD50:1900 mg/kg(mouse via mouth);
280 mg/kg(subcutaneous in mice).
This material is harmful to the environment and can cause pollution to water body and atmosphere. Organic acid is easy to form acid rain in atmospheric chemistry and atmospheric physical changes.
So when the PH value to below 5, can cause serious harm to animals and plants, fish breeding and development will be severely affected, basin sediment in soil and water metal poisoning fish can be dissolved into water.Water acidification can also cause changes in the composition of aquatic organisms, with the increase of acid-resistant algae and fungi, as well as the reduction of root plants, bacteria and vertebrates, and degradation of organic matter.Acidification can result in the loss or death of fish in lakes and rivers.
Protective measures： Respiratory system: when the concentration of dust in the air exceeds the standard, you must wear a self-priming filter respirator.For emergency rescue or evacuation, air respirator should be worn;
