Abstract
PURPOSE: To obtain the title compound in high purity, by hydrolyzing a halonitrobenzene with an aqueous solution of an alkali metal hydroxide in the presence of an oxyacid salt of chlorine.
CONSTITUTION: Alkali metal salts of nitrophenol are obtained by hydrolyzing a halonitrobenzene with an aqueous solution of an alkali metal hydroxide such as sodium hydroxide, in high purity in the presence of an oxyacid salt of chlorine, such as hypochlorous acid, chlorous acid or chloric acid, thereby suppressing the formation of colored substances and other side reactions. Compared with a conventional method using ammonia, an oxygen-containing gas, hydroperoxide, etc., the reaction of this invention can be carried out in a homogeneous phase using an inexpensive iron autoclave. Formation of colored by-products such as azo compounds can be suppressed because the reaction system is not reductive.
