3,4′-Dichlorodiphenyl ether Use and Manufacturing
The preparation method is to add 1, 3-dichlorobenzene and 4-chlorophenol in N-methylpyrrolidone solvent, then add potassium carbonate and the catalyst basic copper carbonate, heat to 170～173℃ and then heat for several hours, cool and filter , Acidified with hydrochloric acid to pH=6～6.5, then distilled to remove water, then distilled under reduced pressure (2kPa), first remove the remaining 1, 3-dichlorobenzene and N-methylpyrrolidone, and then continue to distill Get the product.
Widely used as pharmaceutical and pesticide intermediates
