Terephthalic acid has been successfully degraded using ZnO thin films, without the use of external catalyst like HClO 4, H 2 O 2 etc. Terephthalic acid (PTA), a monomer in the synthesis of polyethylene terephthalate (PET), is obtained by the oxidation of petroleum-derived p-xylene. 1/6. It is a colorless oily liquid with an odor that is fatty, cheesy, waxy, and like that of goats or other barnyard animals. Tandem enzyme system Then, the polycondensation of LEL or GEG with chloride derivatives of dicarboxylic acids (terephthalic acid, 2,5-furandicarboxylic acid, 2,6-naphthalenedicarboxylic acid, and adipic acid) were performed to produce a series of periodic copolyesters such as poly((ethylene diglycolate) terephthalate) (poly(GEGT)) and poly((ethylene di(l-lactate)) terephthalate) (poly(LELT)). Caproic acid, also known as hexanoic acid, is the carboxylic acid derived from hexane with the chemical formula CH 3 (CH 2) 4 COOH. Product Code. Expiry.
