This invention relates to a solid catalyst having the composition below for preparing nitriles and its preparation. The catalyst contains molybdenum and phosphorus as main components and can improve the conversion and the selectivity of the process for preparing heteroaromatic nitriles: n n n n Mo x · P y · O z · X · Y n n n nwherein, nMo is molybdenum; nP is phosphorus; nO is oxygen; nX is one or several ammonium ions; nY is one or several mols water; and nx, y and z are respectively the number of atoms of Mo, P and O, wherein y/x is 0.01 to 5 and z is 0.01 to 10. |
