Adipic acid product standard

Adipic acid product standard
Adipic acid is an important organic compound widely used in chemical, pharmaceutical, food and other fields. In order to ensure the quality and safety of adipic acid products, a series of product standards have been developed.
Firstly, the purity of adipic acid is an important indicator. Generally speaking, the purity of adipic acid should be above 99%, and other impurities such as moisture and heavy metals need to be detected. The detection of these indicators requires a series of chemical analysis methods, such as gas chromatography, liquid chromatography, etc.
Secondly, the appearance of adipic acid is also an important indicator. Generally speaking, adipic acid should be white crystalline, odorless, and free of impurities. If there are abnormal colors, odors, or impurities, further testing and processing are required.
In addition, the pH value of adipic acid is also an important indicator. Generally speaking, the pH value of adipic acid should be between 2.5-3.5, and if it exceeds this range, adjustments need to be made.
Finally, packaging and storage of adipic acid are also very important. Adipic acid should be packaged in sealed containers to avoid moisture and contamination. Meanwhile, adipic acid should be stored in a dry, cool, and well ventilated place, avoiding heat and direct sunlight.
In short, the product standards for adipic acid are very strict and require testing and control of multiple indicators. Only by ensuring the quality and safety of adipic acid products can they be better applied in various fields, bringing more convenience and benefits to human production and life.
