    Abstract: A process for the production of a nitrile having three to 12 carbon atoms per molecule by contacting at a temperature of 400* to 500* C and a contact time of 10 to 0.1 seconds a gaseous mixture of hydrocarbons of three to 12 carbon atoms containing the group AND AMMONIA WITH AN IRON AND ARSENIC CONTAINING CATALYST HAVING AN ATOMIC RATIO OF IRON TO ARSENIC OF 1.1:1 TO 10:1 PREPARED BY ADDING AN AQUEOUS ARSENATE SALT SOLUTION TO AN AQUEOUS FERRIC SALT SOLUTION, ADJUSTING, THE PH value of the resulting solution to between 0.5 and 6, evaporating and calcining the product.
