    摘要: A process is disclosed for the epoxidation of an olefin with hydrogen and oxygen in the presence of an oxidation catalyst comprising a transition metal zeolite, and a noble metal catalyst comprising a noble metal and an ion-exchange resin. The process is highly productive and selective in making epoxides. A noble metal catalyst comprising a cation-exchanged resin further improves the productivity and/or the selectivity of the process.

    摘要: This invention is a process for oxidizing an organic compound with a hydrogen peroxide solution produced by reacting hydrogen and oxygen in the presence of an oxidation catalyst. The hydrogen peroxide is produced by reacting hydrogen and oxygen in a solvent in the presence of a H2O2-producing catalyst comprising a polymer-encapsulated combination of a noble metal and an ion-exchange resin. Polymer encapsulation of the H2O2-producing catalyst improves its productivity in making hydrogen peroxide and is expected to reduce metal loss.

    摘要: A process is disclosed for the epoxidation of an olefin with hydrogen and oxygen in the presence of an oxidation catalyst comprising a transition metal zeolite and a polymer-encapsulated noble metal catalyst. The noble metal catalyst comprises a noble metal and an ion-exchange resin. The process using the polymer-encapsulated noble metal catalyst gives higher epoxide productivity than a process that uses a noble metal catalyst which is not encapsulated by a polymer.

    摘要: The liquid-phase epoxidation reaction of an olefin with hydrogen and oxygen in the presence of a catalyst mixture containing a titanium zeolite and a supported catalyst surprisingly produces less ring-opened products such as glycols when performed in the presence of a buffer. This is particularly surprising because a typical palladium on titanium zeolite catalyst is little effected by the presence of a buffer. Surprisingly, the use of a buffer also typically improves the activity of the process.
