Reaction Steps

The reactor was charged with a catalyst having the composition 50% K0.4 Ce0.58 Cu0.58 POx +50% Al2O3 (see Example 7). The testing procedure was essentially the same as that of Examples 2-10, except that the liquid feed consisted of methyl acetate alone, while the gaseous feed consisted of oxygen, nitrogen, and dimethyl ether. The composition of the gaseous feed and the respective flow rates of the liquid and the gaseous feeds were such that a reactant ratio methyl acetate/dimethyl ether/O2 /N2 =10/0.5/0.8/7.2 was obtained, and the average residence time in the reactor was 10 seconds. At the reaction temperature of 330° C., 45.2% ppc of methyl acrylate and 4.6% ppc acrylic acid were obtained, resulting in 49.8% ppc to total product. At 350° C. the yields were 82.1% ppc to methyl acrylate and 13.6% ppc to acrylic acid, resulting in 95.7% ppc to total product.
