Physical properties of Adipic Acid
Adipic acid is a white crystal and has a smell of scorched bones. It's slightly soluble in water and freely soluble in most organic solvents such as alcohol and ether.
Melting point: 151-154 °C (lit.)
Boiling point: 265 °C at 100 mm Hg (lit.)
Density: 1.36 g/cm3
State of material: solid
Uses of Adipic Acid
The acidity of adipic acid is slight and long-lasting. Since its PH value changes little within a large concentration range, it is a good PH value modifier. It can also be used for jelly powders and solid beverage powders, with its maximum amounts used respectively up to 0.15 g/kg and 0.01 g/kg.
It is primarily used as a raw material for nylon 66 and engineering plastics and secondly used as plasticizers and advanced lubricants in the production of various ester products. In addition, adipic acid is used as a raw material for polyurethane elastomers and an acidifying agent for various foods and beverages. Its function and use are sometimes superior to citric acid and tartaric acid. Adipic acid also serves as a raw material for pharmaceuticals, yeast purification, insecticides, binders, synthetic leather, synthetic dyes and spices.
Storage of Adipic Acid
It should be stored in cool, well-ventilated, rain-proof warehouses and kept away from fire and heat sources. It should be separated from oxidizing agents, reducing agents, and alkalis and never be mixed together. Appropriate types and quantities of fire-fighting equipment and emergency response equipment should be equipped in warehouses.
