In this study, a series of polystyrene-divinylbenzene resins with precise phys. structure regulation and chem. modification were successfully synthesized. The regulation of Friedel-Crafts reaction conditions resulted in several phys. resins with various BET surface areas and pore structures, while the adsorption of 1,3-propanediol revealed that the mol. size and other phys. properties exhibited a moderate contribution to the adsorption of hydrophilic compounds The adsorption processes between 1,3-propanediol and nitrogen, oxygen and boron functional group modified resins were further explored, and boronic acid modified resins named PS-3NB and PS-SBT exhibited higher adsorption capacities than com. resin CHA-111. The adsorption capacity of PS-3NB and PS-SBT reached 17.54 mg g-1 and 17.23 mg g-1, resp., which were 37% and 35% higher than that of com. resin CHA-111. Furthermore, the adsorption mechanism demonstrated that the content of boronic acid, solution pH and adsorbate hydrophobicity were the primary adsorption driving forces. Herein, we provided a method to modify polystyrene-divinylbenzene materials with boronic acid to selectively adsorb hydrophilic polyols via the specific affinity between boronic acid and diol mol. The experimental process involved the reaction of 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6Quality Control of 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane)
