Brief Overview

Terephthalic acid, also known as TPA, appears as a white powder solid and has a relatively poor solubility in water. It is commonly used in the manufacturing of Polyethylene terephthalate (PET) which is widely used in clothing and plastic products.

 

Manufacturing Processes

Terephthalic acid is manufactured by oxidizing para-xylene with acetic acid in the presence of a catalyst such as cobalt acetate. The terephthalic acid produced is subsequently processed through crystallizers to remove any remaining impurities such as unreacted para-xylene before it is dried and recovered.

Plastic Industry

Terephthalic acid is used in the production of polyethylene terephthalate (PET) which is widely used as the primary container resin for most products such as PET bottles. It is popular due to its durability and good heat resistivity which allows it to be used for several applications.

 

Fibre and Film Industry

Terephthalic acid is used in the production of polyester fibers and films which are used in the manufacturing of synthetic fibers, photographic films, labels, videotapes.

 

Other Industry

Terephthalic acid is used as a raw material for certain drugs in the pharmaceutical industry.
