PROCEDE DE PREPARATION D'ACIDE TEREPHTALIQUE |
摘要 |
There is disclosed a process for preparing terephthalic acid by oxidizing p-xylene which comprises contacting a substantially liquid mixture of p-xylene with p-toluic acid and water wherein the molar ratio of p-toluic acid to p-xylene is between about 0.01 and about 100 and the molar ratio of water to p-toluic acid is between about 0.4 and about 60, with a molecular oxygen-containing gas in the presence of an oxidation catalyst. |
