The basic process route is the esterification of terephthalic acid and methanol catalyzed by sulfuric acid or other catalysts. Specific intermittent, continuous, atmospheric pressure, pressure and other different process methods. The more advanced process is continuous combining oxidation with esterification (Wilton method) with p-xylene and
Methyl p-methylbenzoate was used as raw material, and cobalt and manganese metal salts were used as catalyst for pressure oxidation, followed by continuous esterification with methanol to obtain dimethyl terephthalate.
an intermediate of the polyester resin. Also used in the production of insulating paint, adhesive. It can also be used to produce a plasticizer, dioctyl terephthalate.
