Process for the liquid phase oxidation

Claim 2

A PROCESS FOR THE MANUFACTURE OF EPOXIDES FROM OLEFINS HAVING NOT LESS THAN THREE CARBON ATOMS IN THE MOLECULE WHICH COMPRISES PASSING SAID OLEFINE IN THE LIQUID PHASE IN CONJUNCTION WITH AN OXIDATION CATALYST SELECTED FROM THE GROUP CONSISTING OF ORGANIC SALTS OF COPPER, MANGANESE, VANADIUM AND COBALT WITH MOLECULAR OXYGEN THROUGH A REACTION ZONE AT A TEMPERATURE BETWEEN 100* AND 180* C. AT SUPERATMOSPHERIC PRESSURE, CONDUCTING THE OXIDATION MIXTURE ISSUING FROM THE REACTION ZONE THROUGH A SEPARATE ZONE WHEREIN SAID MIXTURE IS RENDERED SUBSTANTIALLY ACID FREE AND RECYCLING THE RESIDUAL MIXTURE CONTAINING EPOXIDE AND OLEFINE WITH MOLECULAR OXYGEN TO THE REACTION ZONE.

Claim 3

A PROCESS FOR THE MANUFACTURE OF EPOXIDES FROM OLEFINES WHICH COMPRISES PASSING AN OLEFINE SELECTED FROM THE GROUP CONSISTING OF PROPYLENE, BUTENES INCLUDING NBUTENES, PENTENES INCLUDING PENTENE-1 AND PENTENE-2, HEXENES INCLUDING HEXENE-1 AND METHYL PENTENE, HEPTENES INCLUDING HEPTENE CUTS FROM PETROLEUM SOURCES, OCTENES INCLUDING ALPHA AND BETA DI-ISOBUTENE, IN THE LIQUID PHASE IN CONJUNCTION WITH AN OXIDATION CATALYST SELECTED FROM THE GROUP CONSISTING OF ORGANIC SALTS OF COPPER, MANGANESE, VANDIUM AND COBALT WITH MOLECULAR OXYGEN THROUGH A REACTION ZONE AT A TEMPERATURE BETWEEN 100* AND 180* C. AT SUPERATMOSPHERIC PRESSURE, CONDUCTING THE OXIDATION MIXTURE ISSUING FROM THE REACTION ZONE THROUGH A SEPARATE ZONE WHEREIN SAID MIXTURE IS RENDERED SUBSTANTIALLY ACID FREE AND RECYCLING THE RESIDUAL MIXTURE CONTAINING EPOXIDE AND OLEFINE WITH MOLECULAR OXYGEN TO THE REACTION ZONE.

Claim 4

A PROCESS FOR THE MANUFACTURE OF EPOXIDES FROM OLEFINES WHICH COMPRISES PASSING AN OLEFINE SELECTED FROM THE GROUP CONSISTING OF PROPYLENE, BUTENES INCLUDING NBUTENES, PENTENES INCLUDING PENTENE-1 AND PENTENE-2, HEXENES INCLUDING HEXENE-1 AND METHYL PENTENE, HEPTENES INCLUDING HEPTENE CUTS FROM PETROLEUM SOURCES, OCTENES INCLUDING ALPHA AND BETA DI-ISOBUTENE, IN THE LIQUID PHASE IN CONJUNCTION WITH AN OXIDATION CATALYST SELECTED FROM THE GROUP CONSISTING OF ORGANIC SALTS OF COPPER, MANGANESE, VANDIUM AND COBALT WITH MOLECULAR OXYGEN THROUGH A REACTION ZONE AT A TEMPERATURE BETWEEN 100* AND 180* C. AT SUPERATMOSPHERIC PRESSURE, CONDUCTING THE OXIDATION MIXTURE ISSUING FROM THE REACTION ZONE THROUGH A SEPARATE ZONE WHEREIN SAID MIXTURE IS RENDERED SUBSTANTIALLY ACID FREE AND RECYCLING THE RESIDUAL MIXTURE CONTAINING EPOXIDE AND OLEFINE WITH MOLECULAR OXYGEN TO THE REACTION ZONE.
