PREPARATION OF TRIHALIDE ANION EXCHANGE RESINS REVERSIBLE ADSORPTION AND CHLORINATION REACTIONS USING ION EXCHANGE RESINS

摘要

The present invention provides a trihalide ion solution in a styrene divinylbenzene polymer resin having a polymer-linked -ER ₃⁺ X ^- group, wherein E is N, P or As, R is a hydrocarbon group, and X is Cl, Br or I. It relates to a method for producing a trihalide resin to be contacted. Tri-halide ion is Cl ₃^- may be ^-, Br ₃^- or I _3. The present invention relates to a method for producing a trichloride resin, and a styrene divinylbenzene polymer resin having a polymer-linked -ER ₃⁺ Cl ^- group in contact with chlorine. Trichloride resin can be used as a solid equivalent of chlorine gas. -ER ₃⁺ Cl ^- form of the styrene-divinylbenzene resin containing a unit -ER ₃⁺ Cl ₃^- may be used to find the chlorine from a gas or a solid to form a styrene-divinylbenzene resin containing a unit.
