31. 5 CHLORO - 2- BENZAXOLONE [Chlorzoxazone]


4-Chloro Amino Phenol [4-CAP] is charged along with HCl, Urea, Acetic Acid andWater & heated to specific elevated temperature till completion of the reaction.The mass is then filtered.

The wet cake is then dissolved in dilute C S Lye and Carbon added followed byfiltration. The filtrate is again treated with HCl solution for isolation of productwhich in turn is further re-crystallized by Methanol for final purification. ThePurified wet cake is then dried to obtain product Chlorzoxazone.

Methanol obtained as ML is further taken for distillation and recycled insubsequent batches.

32. Cloquintocet Mexyl


2-Heptanol is reacted with Monochloro Acetic Acid in Toluene as solvent with aidof P-Toluene sulfonic acid yielding the ester 2-Methyl Hexyl Chloroformatealong with liberation of water which is removed from the reaction mass. Thereaction mass is washed with water and further taken for next step of CloquintocetMexyl synthesis.

2-Methyl Hexyl Chloroformate in Toluene is reacted with 5-Chloro-8-Hydroxyquinoline along with Potassium Carbonate leading to formation ofCloquintocet Mexyl with generation of Potassium salts. The Potassium salt andorganic layer washed with water. Toluene recovered from organic layer and theresidual mass crystallized in Methanol followed by filtrate and drying. Methanolrecycled after recovery.
