- Terephthalic acid is a
carboxylic acid. Terephthalic acid donates hydrogen ions if a base
is present to accept them. This "neutralization" generates
substantial amounts of heat and produces water plus a salt.
- Terephthalic acid is a
sand-like white powder. It is used as a reagent to neutralize alkali
in wool, as an additive to poultry feeds, and to increase the
effectiveness of certain antibiotics.
- PTA is used to
manufacture light-coloured adhesives to bond metal, wood, paper and
synthetics. Specific uses for these high-strength, solvent-free
adhesives include shoe fabrication, lamination and automotive
sub-assembly.
- Purified Terephthalic
Acid (PTA) is used in the industrial fiber industry as one of the
raw materials to make polyethylene terephthalate, more
commonly known as polyester.
- End products produced
from PTA include polyester fabrics, recording tapes, tire cord, food
packaging, and soft drink bottles.
- Terephthalic acid is a
key raw material for polyester production and ranks 25 th in tonnage
of all chemicals produced in the world.
- Terephthalic acid (TPA)
is made by air oxidation of p-xylene and requires purification for
use in polyester fiber manufacture.
- PTA is made by causing
a reaction between the secondary petroleum product paraxylene (PX)
and acetic acid.
- Terephthalic acid
(TA), one of the largest volume commodity chemicals, is commercially
manufactured, by dioxygen oxidation of para-xylene (PX), in a
homogeneous acetic acid (HOAc) medium, using a catalyst combination
of cobalt and manganese salts and bromide ion promoter .
- Terephthalic acid
(TA), one of the largest volume commodity chemicals, is commercially
manufactured, by dioxygen oxidation of para-xylene (PX), in a
homogeneous acetic acid (HOAc) medium, using a catalyst combination
of cobalt and manganese salts and bromide ion promoter.
- The oxidation of
para-xylene to crude terephthalic acid (CTA) catalyzed by metals and
bromide is accomplished in acetic acid. The CTA is then purified to
obtain purified terephthalic acid (PTA).
- More than 60% of the
DMT/TPA produced in the world is used to manufacture PET polymer for
polyester fibers. Another 31% goes into the manufacture of PET
solid-state resin for bottles and other packaging applications.
- China is by far the
largest TPA producer in the world and accounted for a share of about
28% in 2009. Other major producers are the Republic of Korea, Taiwan
and Thailand. The latter three export about half of the TPA
produced, accounting for nearly 80% of the global trade, with the
rest consumed in PET solid-state applications.
- Nearly all purified
terephthalic acid (PTA) is consumed in polyester production
including polyester fibre, polyethylene terephthalate (PET) bottle
resin and polyester film. For most grades of polyester used in
textiles and food and beverage containers, it is more economical to
use PTA than the alternative dimethyl terephthalate (DMT)
intermediate.
- The remaining PTA is
used in making cyclohexanedimethanol, terephthaloyl chloride,
copolyester-ether elastomers, plasticisers and liquid crystal
polymers.
- A major challenge
facing the PTA industry is the growing overcapacity caused by huge
capacity additions of nearly 9m tonne/year under
development, mainly in China. Up to three PTA units could be started
up in China by mid-2009 although two of these could face delays.
