| titleOfInvention | Improved method for purifying 4-halodifluoromethoxy neophyll 3-phenoxybenzyl ethers |
| abstract | (57) [Summary] (Modified) [Structure] 4-Halodifluoromethoxyneophyl 3- Crude phenoxybenzyl ethers are treated with an alkaline aqueous solution in the presence or absence of an aliphatic hydrocarbon solvent, and then 4-halodifluoromethoxyneophyl 3-phenoxybenzyl ethers are extracted with an aliphatic hydrocarbon solvent. After that, the aliphatic hydrocarbon solution containing the compound is treated with activated carbon. [In the formula, R represents a hydrogen atom or a chlorine atom, Y represents a hydrogen atom or a fluorine atom, and X represents a chlorine atom or a bromine atom. ] The purification method of 4-halo difluoro methoxy neophyll 3-phenoxy benzyl ether represented by these. [Effect] By refining impurities generated as by-products during the production by alkali treatment and decomposing the impurities, the purification effect can be improved as compared with the conventional purification method, and further isolation and purification can be performed with stable purity and high yield. . |
