Sebacic Acid is a
white flake or powdered crystal. It is resolved in ethanol, ether and soluble
slightly in water. Sebacic Acid was named from the Latin
sebaceus (tallow candle)
or sebum (tallow) in
reference to its use in the manufacture of candles. Sebacic Acid and its
derivatives such as azelaic acid 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.
There are almost infinite esters obtained from thousands of potential starting
materials. Esters are formed by removal of water from an acid and an alcohol,
e.g., carboxylic acid esters, phosphoric acid esters, and sulfonic acid esters.
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.
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
