Abstract:
A process for the preparation of hydrogen cyanide which consists essentially of providing an electrically nonconductive reaction tube, disposing within the volume of said reaction tube a platinum group-metal catalyst in the form of a metal gauze, said catalyst having an electrical conductivity of at least about 1.0 Siemens per meter, heating said catalyst to a temperature between 600 and 1200.degree. C. by disposing said reaction tube within a solenoid coil and applying to said coil an alternating magnetic field sufficient to cause the solenoid coil to resonate at a frequency determined by the electrical properties of the solenoid coil and a capacitor connected in parallel therewith, and passing a mixture of ammonia vapor and methane through said reaction tube containing said heated catalyst, and recovering hydrogen cyanide.
