Zusammenfassung: | The invention discloses a preparation method of a molybdic acid phenyl ester modified high ortho-position thermoset phenolic base hollow nanometer gradient activated carbon fibrous membrane. The method comprises the following steps that a phenol compound, molybdic acid, an alcohol compound and hydrochloric acid are subjected to a constant temperature reaction under the temperature of 75-90 DEG C,an aldehyde compound is added, a heating boiling reaction is performed under the effect of a catalyst, a concentrated sulfuric acid solution is added dropwise, decompression and water extraction are performed to obtain molybdic acid phenyl ester modified high ortho-position phenolic resin; the molybdic acid phenyl ester modified high ortho-position phenolic resin is dissolved into an alcohol and aldehydes compound to have a reaction under the effect of another catalyst, and molybdic acid phenyl ester modified high ortho-position thermoset phenolic resin is obtained; the molybdic acid phenyl ester modified high ortho-p |
