Product Details

Products Description of Dimethyl terephthalate CAS#120-61-6
Dimethyl terephthalate (DMT) is a key precursor in the production of polyethylene terephthalate (PET), widely recognized for its applications in the manufacturing of plastic bottles, fibers, and films. In academic and industrial R&D, DMT is the subject of innovative research, such as its hydrogenation to dimethyl cyclohexanedicarboxylates (DMCD) using bimetallic catalysts, which has demonstrated an 80% conversion rate and 95% selectivity under optimized conditions 43. Moreover, sustainable approaches to PET depolymerization, leveraging copper-supported catalysts, have been developed to recycle PET waste back into high-value DMT monomers with remarkable efficiency 45. Production parameters of DMT are characterized by a melting point range of 139°C to 142°C, and it is classified as a combustible solid with a flash point of 154°C 47. These attributes make DMT an essential compound in the chemical industry, with a strong focus on both its production capabilities and its role in creating sustainable materials.
