CATALYST SYSTEM FOR PRODUCTION OF ACIDS |
| abstract |
The invention relates to a process for the preparation of isophthalic acid and terephthalic acid used for obtaining resins. The process according to the invention consists in that a stream comprising xylene and ethylbenzene is subjected to the steps of: a. Catalytic oxidation with an oxidation catalyst in the presence of a gaseous oxygen source; b. separation of crude isophthalic acid and crude terephthalic acid; c. recovering and recharging at least a portion of the oxidation catalyst over a solid catalyst recovery bed. |
