Use as intermediates in the production of pyrethroid pesticides

Production methods α-isopropyl p-chlorophenyl acetonitrile hydrolysis derived. The α-isopropyl p-chlorophenylacetonitrile and 65% sulfuric acid molar ratio of 1: 1.3 were mixed, heated to 140-145 ° C for 11h. With solvent extraction, the acid layer was removed, and then washed with water, desolventizing, crystallization of α-isopropyl p-chlorophenylacetic acid, 90%, m.p. 85-87 ° C, yield 90%.

Production Method The preparation method is based on p-chlorotoluene as raw material, the side chain chlorination of chlorobenzyl chloride, and then reacted with sodium cyanide generated p-chloronitrile acetonitrile, and then with isopropyl bromide or isopropyl chloride reaction generated 3-methyl-2- (4-chlorophenyl) butyronitrile, followed by acidic hydrolysis to give 3-methyl-2- (4-chlorophenyl) butyric acid.

The formulated 65% sulfuric acid was put into the reaction kettle, and 3-methyl-2- (4-chlorophenyl) butyronitrile was put into the reaction kettle under stirring, the temperature was gradually raised to 143-145 ° C., the reaction was refluxed for 6 hours, cooled to room temperature, Toluene extraction, still stratification, the separation of toluene solution, acid solution, and then extracted with toluene, toluene solution combined with 10% sodium hydroxide solution extracted twice with a small amount of toluene lye extraction, lye reuse 30% hydrochloric acid was acidified to pH = 1, extracted twice with toluene and the toluene layer was washed with saturated brine to pH = 6, de-toluene to give 3-methyl-2- (4- chlorophenyl) % ~ 85%.
