Embodiment 1

[0020] The preparation method of amphoteric adsorption resin containing pyrrolidone group with high specific surface area comprises the following steps:

[0021] (1) Add gelatin, trisodium phosphate, disodium hydrogen phosphate, and sodium lignosulfonate to the water phase as dispersants. More specifically, in a 2000 ml flask equipped with a stirring and temperature control device, add 500 ml of water, then add 2.5 g of gelatin, 5 g of trisodium phosphate, 6 g of disodium hydrogen phosphate, and 1 g of sodium lignosulfonate, and stir until dissolved.

[0022] (2) The composition of the oil phase is composed of reactants and porogens. The reactants include cross-linking agents and monomers. The cross-linking agents include aliphatic polyunsaturated ester cross-linking agents and divinylbenzene. Among them, the aliphatic polyunsaturated ester crosslinking agent uses 100 g of diethylene glycol dimethacrylate and 100 g of divinylbenzene; the porogen uses 200 g of isoamyl alcohol a...

Description

technical field [0001] The invention relates to the technical field of polymer chemistry, in particular to an amphoteric adsorption resin containing pyrrolidone groups with high specific surface area. The invention also relates to a preparation method of the pyrrolidone group-containing amphoteric adsorption resin with high specific surface area. Background technique [0002] Weak acid and weak base type amphoteric resin is a kind of ion exchange resin containing both weak acid groups and weak base groups. It is used in water treatment to remove inorganic ions. It has the advantages of high working exchange capacity, easy regeneration and low regeneration cost. The amphoteric resin can also be used as a deacidifying agent in chemical production. For example, the Chinese invention patent whose notification number is CN102698819A reports a kind of weak-acid-weak-base amphoteric resin used as a deacidification agent for the production device of MTBE. The resin adopts conventi...
