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

摘要

A method of preparing a trihalide resin, where a trihalide ion solution is contacted with a styrene divinylbenzene polymer resin having polymer bonded -ER3+ X- groups where E is N, P, or As, R is a hydrocarbon group and X is C1, Br, or I. The trihalide ion can be C13 -, Br3 - or I3 -. A trichloride resin and a method of preparing the trichloride resin, where a styrene divinylbenzene polymer resin having polymer bonded -ER3 + C1- groups is contacted with chlorine. The trichloride resin can be used as a solid equivalent of chlorine gas. Formation of the styrene divinylbenzene resin comprising -ER3 +C1- units can be used to scavenge chlorine from a gas or liquid to form the styrene divinylbenzene resin comprising - ER3 +C13 - units.
