| titleOfInvention | Modified composite pore structure adsorption resin and preparation method thereof |
| abstract | The invention discloses a modified composite pore structure adsorption resin and a preparation method thereof. The raw materials comprise the following components in percentage by mass: 36.3-55% of styrene, 7-39% of cross-linking agent, 0.3-0.7% of initiator, 19-53% of pore-forming agent and 0.8-2% of dispersant; preparing an oil phase and a water phase, pouring the oil phase into the water phase to form liquid beads, suspending the liquid beads in the water phase, raising the temperature in stages to harden the liquid beads, pouring out the upper liquid after the reaction is finished, filtering, and collecting resin beads; extracting the resin globule with petroleum ether, soaking the extracted resin globule with methanol, filtering, repeatedly soaking with methanol, filtering to remove petroleum ether remained in the resin, washing with deionized water, removing methanol and other residues in the resin, and obtaining the adsorption resin with a composite pore structure; adding the adsorption resin with the composite pore structure into concentrated nitric acid for nitration reaction, washing and drying a reaction product to obtain the modified adsorption resin with the composite pore structure. |
