Abstract

The oxidation and ammoxidation of isobutene were studied over mixed oxides SnO2/Sb2O4 as catalysts, in a pulse reactor between 598 and 698 K. From the point of view of methacrylonitrile production the catalysts of compositions Sn:Sb=4-5:1 behaved most appropriately at the optimum reaction temperature of 673 K. Below this temperature the production of methacrolein was preferred, even in the presence of ammonia, whereas at higher temperatures total oxidation prevailed.
