The method of preparation of vanadium catalyst TI- pillared clay-based

摘要

A method for preparing ammoxidation catalyst of the selective P supported on Ti-PILC on, a high activity using a composite metal oxide containing Mo and V, the present invention is the presence of water in a hot water bath to produce the vanadyl oxalate by heating with oxalic acid source of vanadium below; were added to the Ti-PILC and Mo source and phosphorus source, 15 at a temperature in the range of 110~450 ℃ in the presence of air resulting mixture the above method which involves time heating in the range of 35 hours, a reactant stream, a temperature of about 350~450 ℃ fixed bed ammoxidation catalyst on the gas mixture containing oxygen (air) methyl-substituted pyridine, and ammonia comprises at passing, on the use of the ammoxidation catalyst in the heteroaromatic nitriles prepared from methyl pyridine.
