Method of separating non-ionized organic solutes from one another in aqueous solution

Claim 1

A METHOD OF SEPARATING FROM ONE ANOTHER A MIXTURE OF AT LEAST TWO WATER-SOLUBLE WEAKLY-IONIZED TO NON-IONIZED ORGANIC COMPOUNDS CAPABLE OF BEING ABSORBED BY AN ION EXCHANGE RESIN AND SUBSEQUENTLY WASHED FROM THE RESIN WITH AN AQUEOUS SOLUTION, WHICH METHOD COMPRISES, FEEDING TO A BED OF AN ION EXCHANGE RESIN IMMERSED IN AN AQUEOUS LIQUID SOLUTION OF AN INORGANIC SALT WHICH IS INERT TO THE ORGANIC COMPOUNDS AND IN A CONCENTRATION BETWEEN THAT OF A 0.1 MOLAR AND A SATURATED SOLUTION, AN AQUEOUS SOLUTION OF AT LEAST TWO WATER-SOLUBLE WEAKLY-IONIZED TO NON-IONIZED ORGANIC COMPOUNDS WHICH ARE NON-REACTIVE WITH SAID ION EXCHANGE RESIN, THEREBY CAUSING THE ORGANIC COMPOUNDS TO BE SELECTIVELY ABSORBED BY SAID RESIN IN AMOUNTS DIFFERENT FROM ONE ANOTHER, AND THUS DISPLACING FROM THE BED OF THE RESIN AN EQUAL VOLUME OF EFFLUENT LIQUID, THEN FEEDING TO THE BED AN AQUEOUS SOLUTION OF SAID INORGANIC SALT IN A CONCENTRATION BETWEEN THAT OF 0.1 MOLAR AND A SATURATED SOLUTION TO DISPLACE A FURTHER AMOUNT OF LIQUID FROM THE BED AND ELUTE THE ORGANIC COMPOUNDS FROM THE RESIN, AND COLLECTING SUCCESSIVE FRACTIONS OF THE DISPLACED EFFLUENT LIQUID, WHEREBY THERE IS OBTAINED A FRACTION OF THE EFFLUENT LIQUID CONTAINING A MAJOR PORTION OF A SINGLE ORGANIC COMPOUND AS THE SOLE ORGANIC SOLUTE AND A SUBSEQUENT FRACTION OF THE EFFLUENT LIQUID CONTAINING A MAJOR PORTION OF ANOTHER OF THE ORGANIC COMPOUNDS AS THE SOLE ORGANIC SOLUTE, UNTIL ALL OF THE ORGANIC COMPOUNDS ARE ELUTED FROM THE BED OF THE RESIN AND COLLECTED IN SEPARATE FRACTIONS OF THE DISPLACED EFFLUENT LIQUID.

Claim 2

A METHOD OF SEPARATING FROM ONE ANOTHER A MIXTURE OF AT LEAST TWO WATER-SOLUBLE WEAKLY-IONIZED TO NON-IONIZED ORGANIC COMPOUNDS CAPABLE OF BEING ABSORBED BY AN ION EXCHANGE RESIN AND SUBSEQUENTLY WASHED FROM THE RESIN WITH AN AQUEOUS SOLUTION, WHICH METHOD COMPRISES, FEEDING TO A BED OF AN ION EXCHANGE RESIN IMMERSED IN AN AQUEOUS LIQUID SOLUTION OF AN INORGANIC SALT WHICH IS INERT TO THE ORGANIC COMPOUNDS AND IN A CONCENTRATION BETWEEN THAT OF A 0.1 MOLAR AND A SATURATED SOLUTION, AN AQUEOUS SOLUTION OF AT LEAST TWO WATER-SOLUBLE WEAKLY-IONIZED TO NON-IONIZED ORGANIC COMPOUNDS WHICH ARE NON-REACTIVE WITH SAID ION EXCHANGE RESIN, THEREBY CAUSING THE ORGANIC COMPOUNDS TO BE SELECTIVELY ABSORBED BY SAID RESIN IN AMOUNTS DIFFERENT FROM ONE ANOTHER, AND THUS DISPLACING FROM THE BED OF THE RESIN AN EQUAL VOLUME OF EFFLUENT LIQUID, THEN FEEDING TO THE BED AN AQUEOUS SOLUTION OF SAID INORGANIC SALT IN A CONCENTRATION BETWEEN THAT OF 0.1 MOLAR AND A SATURATED SOLUTION TO DISPLACE A FURTHER AMOUNT OF LIQUID FROM THE BED AND ELUTE THE ORGANIC COMPOUNDS FROM THE RESIN, AND COLLECTING SUCCESSIVE FRACTIONS OF THE DISPLACED EFFLUENT LIQUID, WHEREBY THERE IS OBTAINED A FRACTION OF THE EFFLUENT LIQUID CONTAINING A MAJOR PORTION OF A SINGLE ORGANIC COMPOUND AS THE SOLE ORGANIC SOLUTE AND A SUBSEQUENT FRACTION OF THE EFFLUENT LIQUID CONTAINING A MAJOR PORTION OF ANOTHER OF THE ORGANIC COMPOUNDS AS THE SOLE ORGANIC SOLUTE, UNTIL ALL OF THE ORGANIC COMPOUNDS ARE ELUTED FROM THE BED OF THE RESIN AND COLLECTED IN SEPARATE FRACTIONS OF THE DISPLACED EFFLUENT LIQUID.
