Diethylbenzene is a very useful crosslinking agent widely used in ion exchange resins, ion exchange membranes, ABS resins, polystyrene resins, unsaturated polyester resins, synthetic rubber, and other fields.
1) Prepare a surface phenolic hydroxyl modified resin. Styrene divinylbenzene resin was prepared by using monomer styrene and crosslinking agent divinylbenzene. Nitrated styrene divinylbenzene resin was obtained by step-by-step bonding of nitro groups on the surface of the resin, followed by reduction reaction to obtain aminated styrene divinylbenzene resin. Finally, surface amino groups were converted to surface phenolic hydroxyl modified resin. The preparation method of the surface phenolic hydroxyl modified resin of the present invention is simple, and the degree of functionalization is highly controllable. By precisely controlling the content of phenolic hydroxyl groups on the surface of the filler, a resin modified material with weak acidic groups is obtained, which can be used as a solid-phase extraction filler. The extraction selectivity for polar compounds in water is high, and the adsorption capacity is large.
2) Preparation of a functionalized nano porous polymer material, including a. Preparation of aldehyde reactants containing double bonds using multi-component synthesis technology. b. Utilize step a to prepare 4-allyloxybenzaldehyde for the Ugi four component reaction to prepare functional monomers. c. Selecting divinylbenzene as the crosslinking monomer, adding an initiator, and using a solvent thermal method to copolymerize divinylbenzene with an appropriate amount of Ugi reaction product, a functionalized nanoporous polymer material is obtained. The mass ratio of divinylbenzene to the functional monomer is 1.0-4.0, the mass ratio of initiator to divinylbenzene is 0.01-0.05, the mass ratio of solvent to divinylbenzene is 4.0-10.0, and the polymerization temperature is in the range of 60-200 ° C, The pressure is controlled between 0.5-5.0 MPa, and the reaction time is 24-48 hours. After the reaction is completed, residual solvents are removed by room temperature volatilization or vacuum distillation.
