| titleOfInvention | Ultrahigh cross-linked resin SX-01 and application thereof |
| abstract | The invention discloses ultrahigh cross-linked resin SX-01 and a preparation method thereof. The ultrahigh cross-linked resin SX-01 is prepared by sufficiently swelling chloromethylated polystyrene resin in nitroethylbenzene the weight of which is 3-8 times that of chloromethylated polystyrene resin; after swelling, adding an amination reagent the weight of which is 2-5 times that of chloromethylated beads, then adding ferric trichloride the weight of which is 10-30% that of the chloromethylated beads to be used as a Friedel catalyst, carrying out Friedel-Crafts and crosslinking reaction at the temperature of 100-150 DEG C, stopping reaction when the content of residual chlorine in the resin is 1-3%, cooling and filtering resin spheres after the reaction is finished, washing with ethanol and distilled water, and carrying out vacuum drying. The invention also discloses a new method for separating pyrimidine nucleotide by utilizing the resin. According to the new method, an adsorption column is adopted for adsorbing and separating uridylic acid, so that dosage of acid and base in an operation process can be reduced, and discharge of waste water can be reduced. |
