US 2001/0020105 A1 · Catalyst for use in production of epoxide, method for producing the catalyst, and method for producing epoxide

Abstract

To provide an epoxide-production-use catalyst that is suitably used for producing an epoxide by partial oxidation of an unsaturated hydrocarbon, a catalyst in accordance with the present invention is obtained by fixing gold fine particles to a carrier containing an oxide containing at least one of titanium and zirconium, and has an acid quantity of not more than 0.1 mmol/g determined by the NH3-TPD method. Such a catalyst for epoxide producing use can be produced by, for instance, fixing gold fine particles to a carrier having an acid quantity of not more than 0.15 mmol/g. The catalyst for epoxide producing use arranged as above is preferably used as a catalyst in partial oxidation of an unsaturated hydrocarbon to produce a corresponding epoxide.

A catalyst for use in production of an epoxide, comprising:

a carrier containing an oxide containing at least one of titanium and zirconium;
and
gold fine particles fixed onto said carrier,
wherein said catalyst has an acid quantity of not more than 0.1 mmol/g, said acid quantity being derived from a quantity of ammonium that, having been absorbed in said catalyst at temperature of 50° C., is desorbed from said catalyst as the temperature rises from 50° C. to 400° C.
