EPOXIDATION PROCESS
A method for the epoxidation of an olefin comprising reacting a feed gas composition containing an olefin, oxygen, and a halocarbon moderator having a first moderator concentration M1 in the presence of an epoxidation catalyst at a first temperature T1; increasing the first temperature to a second t...

| Zusammenfassung: | A method for the epoxidation of an olefin comprising reacting a feed gas composition containing an olefin, oxygen, and a halocarbon moderator having a first moderator concentration M1 in the presence of an epoxidation catalyst at a first temperature T1; increasing the first temperature to a second temperature T2; and increasing the first moderator concentration to a second moderator concentration M2, wherein the second moderator concentration is defined by: M2=M1(1+r)T2−T1 wherein the temperature has the units of degrees Celsius, and r is a constant factor which is in the range of from 0.001% to 100%. |
