    摘要: A partially-oxidizing catalyst for hydrocarbon contains gold, titanium oxide and a carrier whose specific surface area is not less than 50 m.sup.2 /g. The carrier is preferably made from silicon oxide and/or aluminum oxide. The content of gold in the catalyst is preferably set in the range of 0.005 to 5% by weight. Further, another partially-oxidizing catalyst for a hydrocarbon contains gold, a titanium-containing metal oxide, and at least one element selected from the group consisting of an alkaline metal, an alkaline-earth metal and thallium. With these compositions, it becomes possible to provide a partially-oxidizing catalyst for a hydrocarbon having superior activity and selectivity in partially oxidizing the hydrocarbon in the presence of hydrogen and oxygen. Moreover, a partially-oxidizing method for a hydrocarbon is used for partially oxidizing the hydrocarbon by using any of the above-mentioned partially-oxidizing catalysts in the presence of hydrogen and oxygen. This method makes it possible to manufacture an epoxide from a hydrocarbon of the olefin family and also to manufacture an alcohol and/or a ketone from a saturated hydrocarbon, with high selectivity and high conversion.

    摘要: The method of manufacturing an epoxide according to the present invention includes: a dehydrogenation step 1, in which a gas A containing an alkane is dehydrogenated, producing a gas B which contains an alkene and hydrogen; an epoxidation step 2, in which the gas B is epoxidized by use of a gas C containing oxygen in the presence of a catalyst containing gold, producing a gas D which contains an epoxide and unreacted hydrogen and oxygen; a separation step 3, in which the epoxide is separated from the gas D, leaving a gas E; and an oxygen elimination step 4, in which oxygen and hydrogen contained in the gas E are allowed to react, eliminating the oxygen and leaving a gas F. At least part of the gas F (gas F.sub.1) is recycled by returning it to the dehydrogenation step 1. Hydrogen produced in the dehydrogenation step 1 is consumed in the epoxidation step 2 and the oxygen elimination step 4, and thus does not build up in the system of reaction. Accordingly, it is not necessary to separate or eliminate the hydrogen from the system of reaction. In other words, a method can be provided which is industrially advantageous for continuously producing an epoxide from an alkane.
