| titleOfInvention | Method for Hydrotreating Crude Isophthalic Acid |
| abstract | The invention relates to a method for hydrogenation treatment of crude isophthalic acid (crude IA), which mainly solves the problem of poor hydrogenation effect in the prior art. The present invention obtains the TA-containing reaction product after hydrotreating by using the thick IA-containing slurry as the reaction raw material and reacting with a palladium-carbon catalyst in the presence of hydrogen, wherein the reactor used is a fixed-bed reactor, including the reaction The fixed bed reactor of reactor top cover (5) and reactor main body (6), reactor top cover (5) is provided with liquid material feeding port (1) and gas feeding port (4), and reactor main body (6) The technical scheme comprising at least two catalyst frames (11-16) solves this problem well, and can be used in the industrial production of hydrotreating crude IA. |
