Method of making 2,4,4'-trichloro-2'-hydroxydiphenylether

摘要

The invention dibenzo-dioxin and dibenzofuran-current flow as a 2,4,4'- trichloro free of impurities to the method of producing 2'-hydroxydiphenyl ether compounds, are more detail 1,2 -dichlorobenzene and then reacting a phenol compound salt, and chlorinating it, producing a carbonylation-2'-carbonyl diphenyl ether intermediate of 2,4,4'- trichloro to, and re-oxidation by which 2, relates to a process for preparing 4,4'-trichloro-2'-hydroxydiphenyl ether, the method does not produce a toxic substance of the stream-dibenzo-dioxin and dibenzofuran-flow reaction, the toxic by-products there is no removal of the burden, the high yield of the product, the environmental friendly stopped the excess of sulfuric acid used. ; Non-toxic, antimicrobial agents, trichloroacetic Rocca Viterbo nildi ether, trichloroethane hydroxydiphenyl ether, phenol salts.
