Product Description

Products Description of Dimethyl Terephthalate CAS#120-61-6

Dimethyl terephthalate (DMT) is a core PET intermediate used in bottles, fibers and films. Key research areas include its hydrogenation to DMCD and copper-catalyzed PET depolymerization for DMT recycling. It is a combustible solid (mp 139–142 °C, fp ~154 °C) and a critical chemical for industrial and sustainable materials applications.


Product Applications of Dimethyl Terephthalate CAS#120-61-6

Dimethyl terephthalate (DMT) is a core industrial intermediate for PET (bottles, fibers, films) and dioctyl terephthalate (DOTP) production. It is also used in polyester adhesives and engineering plastics, and serves as an intermediate in some PET recycling processes due to its volatility.
