Adipic Acid
High quality of Adipic acid with Reasonable price
Adipic Acid - White crystalline powder mainly as a precursor for the production of Nylon. It is also a monomer for production of Polyurethane and its esters are plasticizers, especially in PVC.
Adipic acid, also known as fatty acid, is an important organic dibasic acid with the structural formula HOOC(CH2)4COOH. It can produce salt reaction, esterification reaction, amidation reaction, etc., and can condense into high polymer with binary amines or diols.

Properties
Adipic acid white monoclinic prism, smell of burnt bone. Relative density 1.360(25ºC), melting point 152ºC, boiling point 337.5ºC(decomposition), flash point (open cup)209.85ºC, ignition point 231.85ºC, melting viscosity 4.54mPa·s(160ºC). Slightly soluble in water and ether, easily soluble in boiling water, easily soluble in , ethanol, soluble in , insoluble in benzene; The aqueous solution is acidic, and the pH value of 0.1% adipic acid aqueous solution is 3.2. It is non-hygroscopic and combustible. It occurs naturally in rancid sugar beets. It has the common properties of dibasic acid and can be esterified to form monoester or diester. When heated to 300ºC, decarboxylated to .
Usage
Organic synthesis, fine chemical and manufacturing of polymer materials, used for the synthesis of diethyl adipate, dibutyl adipate and diisooctyl adipate and other esters, is an important raw material for the manufacture of nylon 66 and polyurethane foam. It is also the raw material of synthetic medicine and spices. It is also used as a lubricant, pH regulator and the manufacture of plasticizers, insecticides and adhesives. In the food industry, it is used as a sour agent, buffer and flavor enhancer for drinks and fruit juices. It is also used to prepare wine and to process cheese. Used in oils and fats can improve the quality of oils and fats. Use as a buffer to prevent Browning of most fruits. Because of its low hygroscopicity, it can be used to make solid powder juice.
