<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a catalyst for acrylonitrile synthesis having an excellent mechanical strength and enabling the acrylonitrile synthesis at a high yield, and a manufacturing method of acrylonitrile. <P>SOLUTION: The manufacturing method of the catalyst for acrylonitrile synthesis incldues the step of manufacturing the catalyst for acrylonitrile synthesis containing a compound oxide containing molybdenum, bismuth, and iron, and silica, and further includes the process of mixing a bismuth component (B) to a first mixture made by mixing a molybdenum component (A) and first spherical silica particles (D) having an average particle diameter of ≥15 nm and <100 nm to prepare a second mixture, and thereafter, mixing second spherical silica particles (C) having an average particle diameter of <15 nm (however, in the process or after the process, an iron component is mixed). <P>COPYRIGHT: (C)2010,JPO&INPIT |
