Properties and Stability
Intermediates for pharmaceuticals and dyes, used in the production of chlorothiadone, 2-chloroanthraquinone, etc.
synthetic method
It is obtained from phthalic anhydride through Friedel Crafts reaction: add chlorobenzene and anhydrous aluminum trichloride into the reaction pot, and slowly add phthalic anhydride. After adding, keep it at 75-80 ℃ for 2.5 hours, cool it, decompose the reaction solution in hydrochloric acid ice water, and let it stand for layering. The chlorobenzene layer is extracted three times with 5% sodium hydroxide solution, the extraction solution is combined, adjusted to pH 2-3 with hydrochloric acid, filtered, dried, and CBB is obtained.
Storage method
This product is sealed and stored in a cool, dry place.
