Embodiment 1
[0012] Dissolve 2 g of sucrose and 2 g of epichlorohydrin in 20 g (20 mL) of distilled water, and stir at room temperature to obtain a transparent solution. Dissolve 1.0mL Span 80 in 100mL chlorobenzene and mix it with the above solution, stir, and add it to the fixed bed reactor filled with D201 macroporous strong basic anion exchange resin to make it exchange in D201 macroporous strong basic anion exchange resin. Polymerize on the resin, react at 22°C for 4 hours, then raise the temperature to 50°C for 2 hours in a water bath. The product was eluted with absolute ethanol to obtain the polysucrose product with a yield of 91.6%.
Embodiment 2
[0014] Dissolve 2 g of sucrose and 5 g of epichlorohydrin in 20 g (20 mL) of distilled water, and stir at room temperature to obtain a transparent solution. Dissolve 1.4mL of Span 80 in 140mL of chlorobenzene and mix with the above solution, stir, add to the fixed bed reactor, make it polymerized on D201 macroporous strongly basic anion exchange resin, react at 27°C for 4.5 hours, and then Raise the temperature to 70°C for 2 hours in a water bath. The product was eluted with absolute ethanol to obtain the polysucrose product with a yield of 92.4%.
Embodiment 3
[0016] Dissolve 3 g of sucrose and 5 g of epichlorohydrin in 25 g (25 mL) of distilled water, and stir at room temperature to obtain a transparent solution. Dissolve 1.8mL of Span 80 in 150mL of chlorobenzene and mix it with the above solution, stir it, add it into a fixed bed reactor, and make it polymerize on a 201×7 (717) macroporous strongly basic anion exchange resin at 25°C After 4.2 hours of reaction, the temperature was raised to 70° C. in a water bath for 2 hours. The product was eluted with absolute ethanol to obtain the polysucrose product with a yield of 92.8%.
