Process for producing halogenated phthalic acid and derivatives thereof |
| abstract |
(57) [Problem] To provide a method for producing halogenated phthalic acid or a derivative thereof, which does not require a high temperature and does not generate impurities. SOLUTION: This production method is characterized in that halogenation of phthalic acid or a derivative thereof with a halogenating agent is carried out in fuming sulfuric acid at a temperature of 100 to 160 ° C in the presence of an iodine-containing compound as a catalyst. |
