ABSTRACT:
This invention relates to a new catalytic process for preparing nitriles such as acetonitrile, propionitrile or benzonitrile, from amides, such as acetamide or alkylacetamides, propionamide or alkylpropionamides, formanilide or alkylformanilides.
According to this invention, the amide is reacted in gaseous phase in a reactor on a solid catalyst of the ammoxidation type, such as bismuth phosphomolybdate, at a temperature comprised between about 400.degree. and 650.degree. C.
