Hydrolysis of Dimethyl Terephthalate for the Production of Terephthalic Acid

open access: yesJOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 2006
Hydrolysis of dimethyl terephthalate (DMT) to produce terephthalic acid (TPA) was studied using a batch reactor. Zink acetate was used as a catalyst to promote the reaction rate. We found that the reaction consists of two reactions: from DMT to mono methyl terephthalate (MMT) and then MMT to TPA.
