Abstract
Dichlorobenzoic acid has been prepared through hydrolysis 2,4 dichlorobenzonitrile, which was obtained by ammoxidation of 2,4 dichlorotoluene. The yied of ammoxidation of 2,4 dichlorotoluene is 88 5% and the purify of 2,4 dichlorobenzonitrile is 98 9% by washing with water. 2,4 Dichlorobenzoic acid is easily obtained by hydrolyzing 2,4 dichlorobenzonitrile in warm reaction condition and the yield is 95 5%.
