[0034] Such as figure 1 Shown, a kind of synthetic method of resin with high adsorption capacity of organic matter of the present invention comprises the following steps:
[0035] S10. Evenly disperse the mixed oil phase of pure divinylbenzene, benzoyl peroxide and template agent in the aqueous phase containing 0.5-2% polyvinyl alcohol, control the stirring speed to 275-300 rpm and the heating temperature, and suspend The method of copolymerization, the oil phase is dispersed into oil droplets of uniform size, and solidified into spherical particles, that is, copolymer I, and washed with hot water for many times;
[0036] It should be noted that, in step S10, the template agent is one or more of toluene, isobutanol, cyclohexane, octane, n-heptane or liquid wax, and the template agent accounts for the mass of the oil phase The ratio is 40-75%.
[0037] It should be further explained that, in step S10, the concentration of pure divinylbenzene in the monomer must be greater tha...
Embodiment 1
[0046] A kind of synthesis method of resin with high organic adsorption capacity of the present embodiment comprises the following steps:
[0047] S10. Configure 1% polyvinyl alcohol solution as the water phase, uniformly disperse the mixed oil phase of 80% pure divinylbenzene, benzoyl peroxide and toluene in the water phase, and the mass of toluene accounts for 50% of pure divinylbenzene , by controlling the stirring speed at 280 rpm, gradually raise the temperature to 78°C, keep stirring for 2 hours, then raise the temperature to 85°C, keep stirring for 6 hours, and disperse the oil phase into oil droplets of uniform size by suspension copolymerization method, and solidify into spherical particles, and the synthesized spherical particles are washed with hot water for many times until they are clean, which is the copolymer I.
[0048] S20, fully soak the copolymer I obtained in step S10 in chloromethyl styrene, keep it warm at 50°C for 2h, and then add 2% initiator to the oil...
Embodiment 2
[0053] The basic content of this embodiment is the same as embodiment 1, the difference is:
[0054] S10. Configure 1% polyvinyl alcohol solution as the water phase, uniformly disperse the mixed oil phase of 85% pure divinylbenzene, benzoyl peroxide, toluene and cyclohexane in the water phase, the total amount of toluene and cyclohexane The mass of toluene accounts for 47% of pure divinylbenzene, and the mass ratio of toluene to cyclohexane is 9:1. By controlling the stirring speed at 290 rpm, gradually raise the temperature to 78°C, keep stirring for 2 hours, and then raise the temperature to 85°C. Insulate and stir for 6 hours, and use the method of suspension copolymerization to disperse the oil phase into oil droplets of uniform size, and solidify into spherical particles, and wash the synthesized spherical particles with hot water for many times until they are clean, which is copolymer I.
[0055] S20, fully soak the copolymer I obtained in step S10 in chloromethyl styren...
