Embodiment 1
[0032] 1. Synthesis of styrene / divinylbenzene / methyl acrylate macroporous resin balls
[0033] Dissolve 4g of magnesium sulfate, 5g of gelatin, and 0.2g of methylene blue in distilled water to prepare 1000mL of water phase.
[0034] Add 258g of styrene, 30g of divinylbenzene, and 12g of methyl acrylate into a mixture of 150g of gasoline and liquid wax with a volume ratio of 2:5, and mix well as the oil phase.
[0035] Add 1000mL water phase into 2000mL reactor, heat to 55°C, then add 550mL oil phase, stir to disperse the oil phase into the water phase, control the particle size to 0.3-1.0, raise the temperature to 75°C, react for 3h, continue to heat up to 90°C, reacted for 3h, raised the temperature to 95°C again for 5h, stopped the reaction, and cooled. After the cooled resin balls are discharged, they are washed with hot water above 90°C, extracted with 5 times the volume of resin in methylal, washed, boiled, and dried at 80-90°C for more than 10 hours to obtain benzene wi...
Embodiment 2
[0041] In step 2 of this example, 100 g of styrene / divinylbenzene / methyl acrylate macroporous resin balls with a crosslinking degree of 6% and 500 g of methyl chloride ether were added to the reaction kettle, and swelled at room temperature for 2 hours. After the swelling was completed, Add 50g of zinc chloride, raise the temperature to 45°C, keep it warm for 2 hours, then add 40g of zinc chloride, and continue the reaction for 12 hours; after the reaction, recover the chloromethyl ether mother liquor, wash with chlorine balls, and dry. The chlorine content in the obtained chlorine spheres was 19%. The other steps were the same as in Example 1 to obtain a hydrophilic macroporous adsorption resin containing hydrogen bonds.
Embodiment 3
[0043] In step 1 of this example, 255 g of styrene, 30 g of divinylbenzene, and 15 g of methyl acrylate were added to a mixture of 150 g of gasoline and liquid wax at a volume ratio of 2:5, and mixed well as the oil phase. The other steps were the same as in Example 1 to obtain a hydrophilic macroporous adsorption resin containing hydrogen bonds.
