GENERAL DESCRIPTION & APPLICATIONS
Adipic Acid (also called hexanedioic acid) is a white, crystalline compound of  C6 straight-chain dicarboxylic acid; slightly soluble in water and soluble in alcohol and acetone. Almost all of the commercial adipic acid is produced from cyclohexane through two sequent oxidation processes. The first oxidation is the reacting of cyclohexane with oxygen in the presents of cobalt or manganese catalysts at a temperature of 150 - 160 C, which produce cyclohexanol and cyclohexanone. Then, the intermediates are further reacted with nitric acid and air with a catalyst (copper or vanadium) or without nitric acid. Cyclohexane can be prepared by the hydrogenation of benzene. There are other ways such as the reactions using phenol, butadiene, and various fats as the starting material. Adipic acid consumption is linked almost 90% to nylon production by the polycondensation with hexamethylenediamine. Nylon, having a protein-like structure, is further processed into fibers for applications in carpeting, automobile tire cord  and clothing. Adipic acid is used in manufacturing plasticizers and lubricants components. It is used in making polyester polyols for polyurethane systems. Food grade adipic acid is used as gelling aid, acidulant, leavening and buffering agent. Adipic acid has two carboxylic acid, -COOH, groups, which can yield two kinds of salts. Its derivatives, acyl halides, anhydrides, esters, amides and nitriles, are used in making target products such as flavoring agents, internal plasticizers, pesticides, dyes, textile treatment agents, fungicides, and pharmaceuticals through further reactions of substitution, catalytic reduction, metal hydride reduction, diborane reduction, keto formation with organometallic reagents, electrophile bonding at oxygen, and condensation.

GENERAL DESCRIPTION OF DICARBOXYLIC ACID
Dicarboxylic acid is a compound containing two carboxylic acid, -COOH, groups. Straight chain examples are shown in table. The general formula is HOOC(CH2)nCOOH, where oxalic acid's n is 0, n=1 for malonic acid, n=2 for succinic acid, n=3 for glutaric acid, and etc. In substitutive nomenclature, their names are formed by adding -dioic' as a suffix to the name of the parent compound. They can yield two kinds of salts, as they contain two carboxyl groups in its molecules. The range of carbon chain lengths is from 2, but the longer than C 24 is very rare. The term long chain refers to C 12 up to C 24 commonly. Carboxylic acids have industrial application directly or indirectly through acid halides, esters, salts, and anhydride forms, polymerization, and etc. Dicarboxylic acids can yield two kinds of salts or esters, as they contain two carboxyl groups in one molecule. It is useful in a variety of industrial applications include;
  • Plasticizer for polymers
  • Biodegradable solvents and lubricants
  • Engineering plastics
  • Epoxy curing agent
  • Adhesive and powder coating
  • Corrosion inhibitor
  • Perfumery and pharmaceutical
  • Electrolyte

There are almost infinite esters obtained from carboxylic acids. Esters are formed by removal of water from an acid and an alcohol. Carboxylic acid esters are used as in a variety of direct and indirect applications. Lower chain esters are used as flavouring base materials, plasticizers, solvent carriers and coupling agents. Higher chain compounds are used as components in metalworking fluids, surfactants, lubricants, detergents, oiling agents, emulsifiers, wetting agents textile treatments and emollients, They are also used as intermediates for the manufacture of a variety of target compounds. The almost infinite esters provide a wide range of viscosity, specific gravity, vapor pressure, boiling point, and other physical and chemical properties for the proper application selections.
