Abstract
Polychlorophenol preparation method characterized by the hydrolysis of a polychlorobenzene and in that said method comprises the reaction phases of a mixture consisting essentially of a polychlorobenzene with lower volatile alcohol and a material selected from the group consisting of alkali metal hydroxides and the triple salt NaOH-SO4Na2. CYaevaporation of said alcohol from the reaction product of said mixture, dissolution of the residue, separation of the alkali-insoluble material from the resulting solution, partial acidification of said solution and subsequent filtration thereof to obtain a substantially pure polychlorophenol.
