High efficiency high purity terephthalic acid production method using composite bromine catalyst system |
| abstract |
The present invention relates to a method for producing terephthalic acid, and more particularly, in the preparation of terephthalic acid by oxidizing paraxylene using a complex metal catalyst of cobalt, manganese and bromine in the presence of acetic acid solvent and oxygen, 150 to 200 Corrosion of the reaction plant by lowering the concentration of bromine to less than 500 ppm and the total catalyst input to 350 ppm to 1000 ppm by selecting bromoacetic acid as a new precursor of bromine under conditions of temperature of 10 ° C. and pressure of 10 to 50 kgf / cm 2 . It relates to a method for producing terephthalic acid to ensure the safety of the process and improved yield and economics. |
