Abstract

In a modification of the process for the manufacture of acrolein and methacrolein by the catalytic oxidation of propylene and isobutene respectively with gases containing molecular oxygen at temperatures between 230 DEG and 400 DEG C. by passing the reacting gas mixture in the presence of elementary selenium over a contact material comprising initially copper oxide distributed upon activated alumina, the activated alumina is replaced by natural bauxite. It is desirable to use a bauxite as carrier which contains only a minor amount of iron compounds. Other features of the process are described in the parent Specification and the efficiency of the contact material may be increased by heat treatment at high temperatures. In the example bauxites containing varying proportions of iron are ground, heated and treated with warm aqueous copper nitrate. The liquid is drained off and the residue is dried and heated. The yields of acrolein obtained by passing a stream of propylene in air and selenium over the heated contact materials are compared.
