Abstract
PURPOSE: To prepare the title compounds in high conversion, selectivity and yield, by the gas-phase catalytic oxidation of isobutylene and/or tert-butanol with O2, in the presence of specific catalytic composition having high activity and selectivity at low temperature.
CONSTITUTION: The objective compounds are prepared by the gas-phase catalytic oxidation of isobutylene and/or tert-butanol with molecular O2 or an O2-containing gas, in the presence of a catalyst I (X is at least one element selected from Cu, Ag, Zn, Cd, Al, Ge, Sn, Pb, Sb, Bi, Mg, etc.; a, b, c, d and e are number of atoms of respective elements; when a is 10, o<b≤6, 0.5≤C≤10, 0.01≤d≤5, and e is determined by the valences and atomic ratios of other elements, and usually between 35 and 80), e.g. compounds of II, III, etc. The heat resistance, life, yield, etc. of the catalyst are further improved by supporting the catalyst to a carrier.
