The invention is further related to the use of such catalysts in the ammoxidation of propylene and isobutylene to acrylonitrile and, respectively, methacrylonitrile.
- Catalysts for the oxidation, ammoxidation and oxydehydrogenation of olefins are well known. See, for example, U.S. 3,642,930 and U.S. 3,414,631, the disclosures of which are incorporated herein by reference. Further note commonly assigned US-applications Serial No. 490,532 filed July 22, 1974, Serial No. 380,527 filed July 19, 1973, and Serial No. 717,838 filed August 26, 1976, the disclosures of which are also incorporated herein by reference. Although these catalysts of the art are very desirable, the catalysts of the present invention have significant advantages over these other catalysts.
- . The present invention is based on the discovery that certain oxidation catalysts based on iron, bismuth and molybdenum and containing additional specified promoter elements exhibit excellent catalytic activity for a variety of olefin oxidation, ammoxidation, dehydrogenation and oxydehydrogenation reactions. In particular, it has been found that specific catalytic compositions as described below are especially suited for use in producing acrylonitrile and methacrylonitrile by the ammoxidation of propylene and isobutylene, respectively. In addition to being excellent ammoxidation catalysts for the production of acrylonitrile or methacrylonitrile, these catalysts also exhibit excellent catalytic activity for the conversion of olefins having four or more contiguous carbon atoms to the corresponding diolefins, and in the oxydehydrogenation of olefins to diolefins.

Similarly, when the inventive catalysts are employed to catalyze other well known reactions, the reaction conditions employed are those- which are conventional.
- A solution of 127.1 g. ammonium heptamolybdate (NH4)6Mo7O24·4H2O and water was prepared. To this solution was added 6.9 g. of a 42.5% solution of H3P04 and 102.7 g. of Nalco 40% silica sol to form a slurry. Separately, an aqueous solution containing 72.7 g. ferric nitrate, Fe(NO3)3·-9H20; 29.1 g. bismuth nitrate, Bi(NO3)3·5H2O: 78.6 g. cobalt nitrate Co(NO3)2·6H2O; 43.6 g. nickel nitrate Ni(NO3)2·6H2O: and 6.1 g. of a 10% potassium nitrate solution was prepared. The solution of metal nitrates was slowly added to the slurry. The resulting slurry was evaporated to dryness, and the solid obtained was heat treated at 290°C for three hours, at 425°C for three hours and at 550°C for 16 hours.
- In the same manner as discussed in Comparative Example A, catalysts listed in the following TABLE I were prepared. Each of these catalysts as well as Comparative Catalyst A was tested for Its catalytic activity in the ammoxidation of propylene to acrylonitrile. In carrying out this test, each of the catalysts was charged into a 5 cc. fixed-bed reactor. A feed of propylene/ammonia/oxygen/ nitrogen/steam in amounts of 1.8/2.2/3.6/2.4/6 was fed to the reactor such that the WWH was 0.1 g. propylene per gram catalyst per hour and the contact time was three seconds. The reaction temperature was maintained at 420°C. The results obtained as well as the results obtained when Comparative Catalyst A was employed was set forth in the following TABLE I.
- Using the various catalysts prepared in the manner described above, additional examples in which propylene was ammoxidized to acrylonitrile were conducted. These additional experiments were conducted in accordance with the same procedure used in Exanples 1 to 7, except that the reaction temperature was 430°C, the contact time was 6 seconds and the catalyst support was 505 SiO2. The results obtained are set forth in the following TABLE II.
