Abstract
a , b -Unsaturated aliphatic aldehydes are prepared by contacting a mixture of a olefinic hydrocarbon having 3-10 carbon atoms and a gas containing molecular oxygen having a mol ratio of oxygen to olefinic hydrocarbon below 1, with a copper-containing catalyst at a temperature between 275 and 400 DEG C. in a first reaction zone, adding a gas-containing molecular oxygen to the effluence from said first reaction zone so that an admixture having a mol ratio of oxygen to olefinic hydrocarbon above 1 is formed, and contacting the resulting admixture with a catalyst comprising (a) bismuth, cobalt or nickel, (b) a metal from the left-hand column of Group VI of the Periodic Table, and (c) oxygen, in a second reaction zone at a temperature above that maintained in said first reaction zone and being in the range between 375 and 500 DEG C. Preferably, the catalyst in the first reaction zone contains elemental copper and/or one or more oxides of copper and component (b) of the catalyst in the second reaction zone comprises tungsten or molybdenum. Examples describe the preparation of acrolein and methacrolein. Specification 798,564 is referred to.
