| abstract | (57) [Summary] [Object] To provide a method for industrially producing high-purity 2-chloroterephthaloyl chloride in a high yield. [Structure] 4-Methylbenzoyl chloride was used as a starting material to react with chlorine, and 3-chloro-4-methylbenzoic acid chloride was separated from the obtained reaction product. Chloro-4-methylbenzoic acid chloride was reacted with chlorine under light irradiation to give 3-chloro-4-trichloromethylbenzoic acid chloride, and the resulting 3-chloro-4- This is a method for producing highly pure 2-chloroterephthalic acid chloride by hydrolyzing trichloromethylbenzoic acid chloride in the presence of a Lewis acid catalyst. [Effects] High-purity 2-chloroterephthalic acid chloride is obtained in high yield by using 4-methylbenzoic acid chloride, which is inexpensive and easily industrially available, as a raw material and does not pass through a difficult-to-handle high-melting-point substance as an intermediate. It can be produced, and is industrially very advantageous in terms of raw materials, reaction equipment, and economy. |
