APPLICATIONS

Glutaric acid
(Pentanedioic Acid)is a dicarboxylic acid with five carbon atoms, occurring in
plant and animal tissues. Glutaric acid is
found in the blood and urine. Alpha-ketoglutaric acid, a derivative of glutaric acid which has a ketone group
on the carbon atom next to the acid group, is produced from glutamate in amino
group and found as an intermediate in the Krebs cycle in the body. In
industrial field, ketoglutaric acid exhibits typical carboxyl group chemistry
useful in a variety of industrial applications. It is a white crystalline solid
having has the lowest melting point among dicarboxylic acids (98 C). It is very
soluble in water and the solution is a medium strong acid. The molecular
structure of odd carbon number is also useful to decrease polymer elasticity.
Glutaric acid is used in the production of polyester polyols, polyamides, ester
plasticizers and corrosion inhibitors. It is used in the synthesis of
pharmaceuticals, surfactants and metal finishing compounds. Alpha-ketoglutaric
acid is used in dietary supplements to improve protein synthesis. |

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.
