ABSTRACT:
The present invention relates to a sold catalyst for manufacturing of a nitrile compound and a method of preparation thereof. More particularly, this invention relates to the solid catalyst expressed by the following formula (1): BiaAaBbQqOx][(100-z) % DdEeFefNigMomOy+z % SiO2] comprising a core catalytic phase expressed by [(100-z) %=DdEeFefNigMomOy+z % SiO2] and a shell catalytic phase expressed by [BinAaBbQqOx], which increases a yield in the manufacturing of a nitrile compound via ammoxidation of olefin, and the method of preparation thereof.
