METHOD FOR THE CONVERSION OF HIGHER FATTY ACIDS TO ALKANE NITRILES HAVING A SHORTER CHAIN LENGTH THAN SAID FATTY ACIDS AND CONTAINING FROM ABOUT 4 TO 10 CARBON ATOMS, WHICH COMPRISES OXIDIZING A HIGHER FATTY ACID IN THE VAPOR PHASE AT A TEMPERATURE RANGING FROM ABOUT 325* TO 550*C. WITH AN OXYGEN CONTAINING GAS IN THE PRESENCE OF A CATALYST SELECTED FROM THE GROUP CONSISTING OF HEAVY METALS AND ALUMINUM AND THEIR OXIDES AND MIXTURES THEREOF, AND GASEOUS AMMONIA, THE OXYGEN BEING PRESENT IN AN AMOUNT RANGING FROM ABOUT 2 TO ABOUT 20 TIMES THE MOLAR AMOUNT OF FATTY ACID, AND THE AMMONIA BEING PRESENT IN AN AMOUNT RANGING FROM ABOUT 3 TO 10 TIMES THE MOLAR AMOUNT OF FATTY ACID.
