    Abstract: The present invention relates to a method of treating a crude acetone stream. The method generally includes treating a crude acetone stream which has acetone and at least one low-boiling impurity with a catalyst to form a treated acetone stream that has acetone and at least one higher-boiling impurity and then distilling the treated acetone stream to remove at least a portion of the higher-boiling impurity to produce a purified acetone stream. This is particularly helpful in processes where a more pure acetone is desired, including a process for making purified isopropanol.

    Abstract: The invention is a process for epoxidizing an olefin with hydrogen and oxygen in a solvent comprising acetonitrile in the presence of an quinone-acid salt and a catalyst comprising a titanium zeolite and a noble metal. The process results in higher productivity and improved selectivity to propylene oxide from hydrogen and oxygen, as compared to processes that use only a quinone.

    Abstract: The invention is a process for epoxidizing an olefin with hydrogen and oxygen in the presence of a catalyst mixture containing a titanium or vanadium zeolite and a supported catalyst comprising palladium, gold, and an inorganic oxide carrier. Prior to its use in the epoxidation process, the supported catalyst is calcined in the presence of oxygen at a temperature from 450 to 800° C. and reduced in the presence of hydrogen at a temperature greater than 20° C. The process results in significantly reduced alkane byproduct formed by the hydrogenation of olefin.

    Abstract: 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.

    Abstract: 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.
