Abstract: FOREIGN PRODUCTS INCLUDING THE NEUTRAL ORGANOPHOSPHOROUS COMPOUNDS AND THE IRON SALTS NORMALLY PRESENT IN COMMERICAL BIS(2-ETHYL-HEXYL)PHOSPHORIC ACID (HDEHP), AND THE RADIOLYTIC DEGRADATION PRODUCTS OF HDEHP ON EXPOSURE HDEHP TO BETA AND GAMMA IRADIATION ARE REMOVED FRO HDEHP CONTAINING ONE OR MOR OF SUCH PRODUCTS BY CONTACTING THE SAID FOREIGN PRODUCT SCONTAINING HDEHP WITH A MACRORETICULAR ANION EXCHANGE RESIN IN BASE FORM WHEREBY THE DEHP- ION OF HDEHP EXCHANGES WITH THE ANION OF THE RESIN AND IS THUS ADSORBED ON THE RESIN AND THE SAID FOREIGN PRODUCTS ARE NOT ADSORBED AND WILL PASS THROUGH A BED OF PARTICLES OF THE RESIN. THE ADSORBED DEHP- ION IS THEN ELUTED FROM THE RESIN AND ACIDIFIED TO FORM AND RECOVER THE PURIFIED HDEHP.

Abstract: A PROCESS FOR ADSORBING OR REMOVING COMPOUNDS, ESPECIALLY POLAR COMPOUNDS FROM NON-POLAR COMPOUNDS IS DISCLOSED. AN EXAMPLE IS THE ADSORPTION OF ALPHATIC ALCOHOLS OR PHENOLIC COMPOUNDS FROM ORGANIC SOLVENTS. THE ADSORPTION PROCESS UTILIZES CROSS-LINKED ADSORBENT RESINS CONTAINING TERTIARY AMINE OXIDE FUNCTIONALITY.
