CATION EXCHANGE RESIN WITH AN INTRAMOLECULAR ANNULAR QUATERNARY AMMONIUM SALT STRUCTURE CAPABLE OF KEEPING THE CHANGE SPEED OF MONOVALENT ION AND POLYVALENT ION HIGH, A TREATING METHOD THEREOF, AND A MIXED LAYER ION EXCHANGE RESIN INCLUDING THE SAME

摘要

PURPOSE: A cation exchange resin, a treating method thereof, and a mixed layer ion exchange resin including the same are provided to have cation exchange speed equal to the previous treatment and the excellent exchange performance of divalence cation especially compared to the normal treatment.;CONSTITUTION: A cation exchange resin is treated by the water-soluble cation polymer electrolyte and is a cation exchange resin having an intramolecular annular quaternary ammonium salt. A compound having an intramolecular annular quaternary ammonium salt structure is represented by the chemical formula 1. In the chemical formula 1, R1 and R2 represent a linear or branched alkyl group which has one to ten carbon atoms and independently has a substituent, R3 represents an alkylene group which is single-bonded and has one to five carbon atoms, and X represents chlorine, bromine, iodine or OH.;COPYRIGHT KIPO 2013
