Synthesis of dimethyl terephthalate

Preparation of dimethyl terephthalate

Preparation of dimethyl terephthalate

Preparation of dimethyl terephthalate

10 g of terephthalic acid are warmed with 13 g of phosphorus pentachloride until liquefaction occurs, 20 g of methyl alcohol are added, and the whole refluxed for 2 hours. On cooling, the precipitate is filtered off and recrystallised from methyl alcohol. Yield 80%, colourless crystals; insoluble in water; m.p. 140° C.
