CONTINUOUS RECIRCULATION OF THE OLEFIN WHICH HAS NOT BEEN REACTED IN THE OXIDATION OF OLEFINS BY HYDROPEROXIDES, BY MEANS OF COMPRESSION AND PRESSURE DISTILLATION

摘要

PROCESS FOR THE CONTINUOUS RECIRCULATION OF THE OLEFIN WHICH HAS NOT BEEN REACTED IN THE EXPOXIDATION OF OLEFINS BY MEANS OF HYDROPEROXIDE TO GIVE OXIRANES AND IS PRESENT IN THE OFFGAS STREAM FORMED DURING THE EPOXIDATION, WHICH COMPRISES THE STEPS (I) TO (III) (I) COMPRESSING AND COOLING THE OFFGAS STREAM, (II) SEPARATING OLEFIN FROM THE OFFGAS STREAM OBTAINED IN STEP (I) BY DISTILLATION, (III) EPOXIDIZING THE OLEFIN SEPARATED OFF INSTEP (II) BY MEANS OF HYDROPEROXIDE.
