Methodology

Dimethyl terephthalate (DMT) is used mainly to produce polyester resins, fibres and films as well as engineering resins. The polyesters generated are employed in fibres used by the textile industry, the manufacture of food and beverage containers such as polyethylene terephthalate (PET) bottles, and polyester film which has applications in photography, computers, audio-visual equipment and packaging.

DMT is available in molten (liquid) and flake (solid) forms. The most widely used method of manufacture is based on paraxylene using oxidation and esterification steps.

DMT is stable under normal temperatures and pressures but is a significant dust explosion hazard if in powder or granular form and mixed with air. It degrades in the atmosphere with an estimated half-life of 28 days.
