Abstract: PURPOSE:To purify a 4-halodifluoromethoxyneophyl 3-phenoxybenzyl ether to a high purity by extracting the crude ether with an aliphatic hydrocarbon solvent such as hexane and subsequently treating the extracted product with active carbon. CONSTITUTION:A 4-halodifluoromethoxyneophyl 3-phenoxybenzyl ether of formula II (X is Cl or Br) is obtained by reacting an alkali metal salt of 4- hydroxyphenyl 3-phenoxybenzyl ether of formula I (R is H or Cl; Y is H or F; M is alkali metal) with dibromodifluoromethane or bromochlorodifluoromethane. The raw product of this reaction is treated with an aqueous alkali soln. in the presence or absence of an aliphatic hydrocarbon solvent and subsequently the product is extracted with an aliphatic hydrocarbon soln. (e.g. cyclohexane) to increase its purity up to about 90%. The product is further treated with active carbon to purify the compound of formula II to a higher purity.
