Description and Uses
Dimethyl terephthalate (DMT) is an organic compound with the formula C6H4(CO2CH3)2. It is the diester formed from terephthalic acid and methanol. It is a white solid that melts to give a distillable colourless liquid.
Dimethyl terephthalate is used widely as an industrial intermediate to manufacture polyethylene terephthalate (PET) and dioctyl terephthalate (OECD, 2001).It is used in the Polyester Film (Audio/Video Tape,X-ray Film,Photo Film), Polyester Fiber, Pet Bottle, Polyester Adhesive, Engineering Plastics. DMT is volatile, it is an intermediate in some schemes for the recycling of PET.
