Abstract

1326882 Unsaturated aldehydes JAPANESE GEON CO Ltd 17 Aug 1970 [20 Aug 1969 6 May 1970] 39576/70 Heading C2C [Also in Divisions B1 and C5] Olefins are oxidized to unsaturated aldehydes by reaction in the vapour phase with oxygen in the presence of a catalyst comprising Mo, Bi, Fe, oxygen and alkali metal in specified atomic ratios (see Division B1), at least part of each of the metals being bound directly or indirectly to oxygen. Specified oxidation conditions are 300-650‹ C., a pressure of subatmospheric up to 20 kg./cm<SP>2</SP>., a contact time of 0À01-50 sees. and a molar ratio of olefin to oxygen of 1 : (0À1 -5À0). The process is used for the oxidation of propylene to acrolein and isobutylene to methacrolein. If desired, the olefin may be simultaneously oxidized and oxidatively dehydrogenated to give a mixture of the unsaturated aldehyde and of conjugated diolefins (see also Division C5). The simultaneous production of methacrolein and 1,3-butadiene from a mixture of n-butane-1 and isobutylene is described. The examples describe the production of acrolein (Example 2), methacrolein (Example 1) and the simultaneous production of methacrolein and 1,3-butadiene (Example 4).
