A PROCESS FOR THE CONCENTRATION OF TERPENE HYDROPEROXIDE SOLUTIONS IN A HYDROCARBON SOLVENT IN WHICH THE SOLVENT IS THE CORRESPONDING TERPENE HYDROCARBON HAVING HIGHER VAPOR PRESSURE THAN SAID HYDROPEROXIDE, WHICH COMPRISES THE STEPS OF PASSING A FILM OF SAID HYDROPEROXIDE SOLUTION THROUGH A FIRST ZONE AT A TEMPERATURE AND PRESSURE SUFFICIENT TO VAPORIZE AT LEAST A PORTION OF SAID SOLVENT, PASSING THE VAPORS FROM SAID FIRST ZONE TO A SECOND ZONE, FEEDING FRESH HYDROCARBON SOLVENT INTO SAID SECOND ZONE CORRESPONDING IN COMPOSITION TO THE TERPENE HYDROCARBON ORIGINALLY USED AS SOLVENT, MAINTAINING SAID SECOND ZONE AT A TEMPERATURE AND PRESSURE THAT THE SUBSTANTIALLY PURE TERPENE HYDROCARBON IS VAPORIZED, RECOVERING SAID SUBSTANTIALLY PURE TERPENE HYDROCARBON FROM SAID SECOND ZONE, WHILE RETURNING ANY HYDROPEROXIDE CARRIED OVER WITH SAID VAPORS TO SAID SECOND ZONE BACK TO SAID FIRST ZONE, AND RECOVERING THE HYDROPEROXIDE-ENRICHED HYDROCARBON FROM SAID FIRST ZONE.
