| titleOfInvention | Method of producing terephthalic acid |
| abstract | The present invention relates to a method for producing terephthalic acid, and more particularly, to a method of preparing terephthalic acid by oxidizing paraxylene using a metal catalyst of cobalt and manganese under an acetic acid solvent, and bromine as a reaction initiator. It relates to a method for producing terephthalic acid wherein the oxidation reaction temperature is 165 to 180 ℃.n n n When terephthalic acid is prepared by oxidizing paraxylene using the method for producing terephthalic acid of the present invention, the loss of acetic acid solvent is low, the organic impurity concentration is low, and the yield is high.n n n n Terephthalic Acid, Acetic Acid, Cobalt, Manganese, Bromine, Paraxylene |
