Method for ammoxidation of saturated hydrocarbon

PURPOSE: To efficiently ammoxidize saturated hydrocarbons by utilizing a solid catalyst whose active phase having a specific composition. CONSTITUTION: In the presence of a solid catalyst, of which the active phase comprises Mo, V and oxygen as well as at least one element selected from Mn, Zn, Co, Cu, Li, Na, K and Ag, and which is preferably shown by the experimental formula of Mo a V b M c O x [M is one or more element selected out of Mn, Zn, Co, Cu, Li, Na, K and Ag; (a), (b) are each less than 2 and neither is 0; (c) is not 0 and less than 1; (x) is determined by the oxydation number of the other elements], saturated hydrocarbons, ammonia and oxygen are allowed to react with each other at 350 to 550°C, preferably 410 to 510°C, under a total pressure of 1 to 6 bar, preferably 1 to 4 bar, and a gas flow of the volumetric rate of 100 to 36000 hr -1 , preferably 200 to 20000 hr -1 . The preferable concentrations in the reactive gas are respectively 5 to 70% hydrocarbon, 3 to 45% ammonia and 3 to 45% oxygen. COPYRIGHT: (C)1994,JPO
