Description

white to off-white powderThe mono-methyl terephthalate is a kind of phthalate ester. It can be obtained during the hydrolytical transformation process of dimethyl terephthalate (DMT) by some microbes such as Rhodococcus rubber and Pasteurella multocida. It is also the intermediate during the manufacturing of dimethyl terephthalate, terephthalic acid and some other derivatives. As the ester form of terephthalate, it is widely used for the manufacturing of plastics, paints, synthetic fibers and p
