| titleOfInvention | A kind of macroporous weakly basic styrene anion exchange resin method and its equipment |
| abstract | The invention relates to a method for macroporous weakly basic styrene anion exchange resin, which comprises the following steps: in step 1, a mixed alcohol of butanol and dodecanol is used as a pore-forming agent, benzoyl peroxide is used as an initiator, gelatin and a small amount of Ammonium salt is used as a dispersant to cross-link and copolymerize styrene and divinylbenzene to obtain a copolymer of styrene-divinylbenzene; step 2, under the catalysis of zinc chloride, chloromethyl ether is used to perform chloromethylation on the white spheres. to obtain a chloromethylated copolymer; in the third step, the chlorine spheres are ammoniated with a dimethylamine solution to obtain a macroporous weakly basic anion exchange resin. Compared with the prior art, the anion exchange resin prepared by the present invention has The specific surface area can reach more than 65m2/g, the proportion of mesopores larger than 2nm is more than 55%, the total exchange capacity can reach 4.6mmol/g, and the weak base exchange capacity can reach more than 3.6mmol/g. |
