| abstract | 1. IN A CONTINUOUS PROCESS FOR THE RECOVERY OF ISOAMYLENES FROM A MIXTURE CONSISTING ESSENTIALLY OF OTHER FIVE-CARBON HYDROCARBONS WHEREIN THE HYDROCARBON MIXTURE CONTAINING ISOAMYLENES IS CONTACTED WITH 50-75% BY WEIGHT SULFURIC ACID IN AN ABSORPTION ZONE TO FORM AN ISOAMYLENE-FAT ACID EXTRACT WHICH IS THEN CONTACTED WITH AN INERT HYDROCARBON SOLVENT EXTRACTANT HAVING A DIFFERENT BOILING RANGE THAN ISOAMYLENE IN A REVERSION ZONE TO SEPARATE TO THE ISOAMYLENES FROM THE ACID AND FORM A LEAN ACID WHICH IS THEN IN PART PURGED AND REPLENISHED BY MAKEUP ACID AND THEN RECYCLED TO THE ABSROPTION ZONE, THE IMPROVEMENT WHICH COMPRISES ADDING THE MAKE-UP ACID aS TWO SEPARATE COMPONENTS, A 90% BY WEIGHT OR GREATER CONCENTRATION SULFURIC ACID ADDITION TO THE LEAN RECYCLE ACID AND A WATER ADDITION TO THE ISOAMYLENE-FAT ACID EXTRACT IN AN AMOUNT SUFFICIENT TO DILUTE SAID ADDED ACID ESSENTIALLY TO THE CONCENTRATION OF THE PURGED ACID; WHEREBY THE CONCENTRATION OF SULFURIC ACID IN THE ABSORPTION ZONE IS GREATER THAN SAID ACID CONCENTRATION IN THE REVERSION ZONE. |
