PROCESS FOR THE MANUFACTURE OF A 1,2-EPOXIDE AND A DEVICE FOR CARRYING OUT SAID PROCESS

摘要

The invention is related to a process for the manufacture of a 1,2-epoxide by catalytic oxidation of a terminal olefin with an oxidant in a multiphasic reaction mixture and at least one organic phase in the presence of a water-soluble manganese complex as oxidation catalyst, comprising the steps of:
a) adding the oxidant, the catalyst and the terminal olefin to the reaction mixture and allowing the catalytic oxidation to take place;
b) separating the reaction mixture into the at least one organic phase and the aqueous phase; and
c) reusing at least part of the aqueous phase.
The invention is also related to a device for carrying out the above process.
