Hydrogen peroxide purification

Claim 1

A PROCESS FOR REMOVING A MONOCARBOXYLIC ACID (HA) HAVING A SINGLE ACID DISSOCIATION CONSTANT KHA BETWEEN 10**-4 AND 10**-5 FROM HYDROGEN PEROXIDE WHICH COMPRISES CONTACTING THE HYDROGEN PEROXIDE WITH A SALT OF A DITO TETRA-BASIC ACID HNB, WHEREIN N IS A WHOLE NUMBER FROM 2 TO 4, AND A STRONG BASE SELECTED FROM THE GROUP CONSISTING OF A QUATERNARY AMMONIUM BASE ANION EXCHANGE RESIN AND A TERTIARY SULFONIUM BASE ANION EXCHANGE RESIN, THE SALT HAVING POLYVALENT ANIONS OF THE POLYBASIC ACID EACH LINKED TO FROM 2 TO 4 EXCHANGE SITES OF THE RESIN, THE POLYBASIC ACID HNB HAVING A FIRST ACID DISSOCIATION CONSTANT WHICH IS GREATER THAN THE ACID DISSOCIATION CONSTANT KHA OF THE MONOCARBOXYLIC ACID AND HAVING ANOTHER DISSOCIATION CONSTANT FOR THE MONOPROTONATED FORM OF THE POLYVALENT ANION WHICH IS ATTACHED TO THE 2 TO 4 SITES OF THE RESIN WHICH IS LESS THAN THAT OF THE MONOCARBOXYLIC ACID, THEREBY BINDING THE MONOCARBOXYLIC ACID TO THE RESIN SALT WITHOUT RELEASING FREE POLYBASIC ACID HNB AND SEPARATING THE HYDROGEN PEROXIDE FROM THE RESULTING RESIN MIXED SALT OF BOTH THE ACIDS HA AND HNB, THE PH OF THE HYDROGEN PEROXIDE BEING MAINTAINED BELOW ABOUT 6.5 THROUGHOUT CONTACT WITH THE RESIN SALT.
