Adipic acid or hexanedioic acid, also known as fatty acid, is an important organic dibasic acid with a structural formula of (CH2)4(COOH)2. It is white crystal or crystalline powder, slightly acidic and capable of sublimation. Slightly soluble in water and ether, easily soluble in ethanol. Stable in nature, low toxicity, irritating to eyes, skin, mucous membrane and upper respiratory tract. It is harmful to the environment and can cause pollution to water bodies and the atmosphere.

It can undergo salt-forming reactions, esterification reactions, amidation reactions, etc., and can polycondensate with diamines or diols to form high molecular polymers. Adipic acid is an industrially important dicarboxylic acid, which plays an important role in chemical production, organic synthesis industry, medicine, and lubricant manufacturing.

What Is Adipic Acid Used For?

Adipic Acid for Sale
  • 1. As an important organic dibasic acid, adipic acid can be used as raw material for nylon 66 and engineering plastics.
  • 2. In the organic synthesis industry, it can be used as the basic raw material of hexamethylene dicyanide and hexamethylene diamine.
  • 3. It can be used in the production of lubricant and plasticizer dioctyl adipate.
  • 4. It is also a raw material for medicine, yeast purification, pesticides, adhesives, synthetic leather, synthetic dyes and fragrances.
  • 5. Adipic acid in food has a mild and long-lasting sour taste, and its pH value changes less in a large concentration range, so it is a better pH value regulator. It can be used as a sour agent in various foods and beverages.

Production Process Introduction

The cyclohexane method is also called the benzene method: this process requires a large one-time investment, produces many by-products, and has three wastes pollution. However, because of its mature technology, most manufacturers currently use this method to produce adipic acid. At present, a new method has been developed on the basis of the benzene method: use a special catalyst to partially hydrogenate benzene to generate cyclohexene, hydrate cyclohexene to generate cyclohexanol nitric acid, and then oxidize to obtain adipic acid.

Phenol is hydrogenated to generate cyclohexanol, and then oxidized with nitric acid to obtain adipic acid. This method is suitable for areas rich in phenol resources.
