Abstract:
A catalyst for acrylonitrile synthesis is disclosed which is composed of particles containing silica and a composite oxide including at least molybdenum. When the Mo/Si atomic ratio in bulk composition of the catalyst is represented by A and the Mo/Si atomic ratio in surface composition of the particles is represented by B, B/A is not more than 0.6.
