Abstract
A process for preparing a catalyst for production of an olefin oxide containing (a) a copper oxide and (b) a ruthenium oxide, which comprises the step of drying a mixture containing a copper component, a ruthenium component, water, and at least one ion selected from the group consisting of a nitrate ion having a molar ratio to the copper of 3 or more and a halide ion having a molar ratio to the ruthenium of 9 or more, and calcining.

A process for preparing a catalyst for production of an olefin oxide comprising (a) a copper oxide and (b) a ruthenium oxide, which comprises the step of
- drying a mixture containing a copper component, a ruthenium component, water, and at least one ion selected from the group consisting of a nitrate ion having a molar ratio to the copper of 3 or more and a halide ion having a molar ratio to the ruthenium of 9 or more, and calcining.
A process for preparing a catalyst for production of an olefin oxide comprising (a) a copper oxide, (b) a ruthenium oxide and (c) an alkaline metal component or alkaline earth metal component, which comprises the step of
- drying a mixture containing a copper component, a ruthenium component, an alkaline metal component or alkaline earth metal component, water, and at least one ion selected from the group consisting of a nitrate ion having a molar ratio to the copper of 3 or more and a halide ion having a molar ratio to the ruthenium of 9 or more, and calcining.
A process for preparing a catalyst for production of an olefin oxide comprising (a) a copper oxide, (b) a ruthenium oxide, (c) an alkaline metal component or alkaline earth metal component and (d) a tellurium oxide, which comprises the step of
- drying a mixture containing a copper component, a ruthenium component, an alkaline metal component or alkaline earth metal component, a tellurium component, water, and at least one ion selected from the group consisting of a nitrate ion having a molar ratio to the copper of 3 or more and a halide ion having a molar ratio to the ruthenium of 9 or more, and calcining.
