| abstract | 1452311 Preparation of terephthalic acid TEIJIN Ltd 1 Nov 1973 [6 Nov 1972] 50843/73 Heading C2C A process for the preparation of terephthalic acid by oxidizing para-xylene and/or para-toluic acid with a molecular oxygen-containing gas in the liquid phase, is characterized in that the reaction is carried out (1) in the substantial absence of a lower fatty acid or halogen compound; (2) in the presence of a Ni compound or a Mn compound (the terms Ni and Mn compounds also include free metallic Ni and Mn), which are at least partially soluble in the reaction mixture, the weight ratio, calculated as metals, of Ni and Mn being 95 : 5-0À5 : 95À5: and (3) at a temperature in the range of 160- 280‹ C. |
