GENERAL DESCRIPTION & APPLICATIONS
Suberic Acid, C-8 dicarboxylic acid, is a white flake or powdered crystal. It is resolved in ethanol, ether and soluble slightly in water. Dicarboxylic acid can yield two kinds of salts, as they contain two carboxyl groups in its molecules. Suberic Acid and its derivatives have a variety of industrial uses as plasticizers, lubricants, hydraulic fluids, cosmetics, candles, etc. It is used in the synthesis of polyamide and alkyd resins.  It is also used as an intermediate for aromatics, antiseptics and painting materials.

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.
