| titleOfInvention | Efficient Reuse of Sodium Halide, a By-Product of 4-Halophthalic Acid Dimerization |
| abstract | The present invention comprises the step of dimerizing 4-halophthalic acid or a salt thereof to prepare a by-product containing 3,3 ', 4,4'-biphenyltetracarboxylic acid and sodium halide (step a); And reacting the by-product containing sodium halide generated in step a with phthalic acid or a salt thereof to prepare 4-halophthalic acid or a salt thereof (step b). In accordance with the present invention, sodium halides can be recovered and reused in the production of 4-halophthalic acid or salts thereof in a manner that does not require a separate recovery process and a particular apparatus. |
