Adipic acidProperties：

Adipic acid, commonly known as fatty acid, is also called hexane dicarboxylic acid, molecular formula for C6H10O4, molecular weight is 146.14.Ar room temperature it is monoclinic crystal.Melting point 152 ℃, boiling point 337.5 ℃, the relative density is 1.366. It is soluble in ethanol, ethyl ether, acetone, etc., product of adipic acid is  white, odorless, crystalline solid.It has   good stability in air, it is slightly soluble in water, easy soluble in alcohol, ether and most organic solvents, it has connectivity of aliphatic dibasic acid, including salt reaction, esterification and amidation reaction, etc.,  it can be condensed into a polymer with diamine.

Applications:Adipic acid can be carried on condensation reaction with polyfunctional  compounds, such as adipic amine. In industry,  using adipic acid with hexamethylenediamine soho reaction  produce nylon 66 salt (AH salt for short), by further polycondensation of nylon 66 salt, can get nylon 66 resin. In addition, reacting with alcohols, adipic acid can produce adipate, used as plasticizer, synthetic lubricant and polyester polyols and other products, can be used for all kinds of food and drink sour agent.  Due to no n-deliquescence, adipic acid is especially suitable for dry food, can be stored for a long time.
