    Abstract: A method for the production of hydrocyanic acid by autothermic, non-catalyzed oxidation of one or several nitrogen-containing hydrocarbons or a nitrogen-containing hydrocarbon mixture, wherein the nitrogen-containing hydrocabons, an oxygen-containing gas, optionally a gas containing nitrogen oxides, optionally water, optionally ammonia, and, optionally other gas components, which behave in a substantially inert manner are placed in a flame reaction zone, are reacted in the flame reaction zone and post-reaction zone at a temperature of 1000 - 1800 °C during a reaction time of 0.03 - 0,3 s to form a cracked gas containing at least the components hydrocyanic acid, carbon oxides, hydrogen, water, ammonia, nitrogen, light hydrocarbons and, optionally, other cracked gas components, whereby the atomic C/N ratio in the reaction zones is 1 - 7 and the atomic excess air coefficient ato is lambdaato

    Abstract: Process for carrying out a high temperature reaction comprises feeding educts to a reaction chamber through channels of a burner block. The high temperature reaction is carried out at temperatures of at least 1500[deg] C with a short dwell time in the reaction chamber and the reaction mixture is rapidly cooled in a quenching region. Process for carrying out a high temperature reaction comprises feeding educts to a reaction chamber (4) through channels (2) of a burner block (3). The high temperature reaction is carried out at temperatures of at least 1500degrees C with a short dwell time in the reaction chamber and the reaction mixture is rapidly cooled in a quenching region (5). Direct cooling to 650-1200degrees C is carried out in the quenching region by introducing a vaporizing quenching medium and indirect cooling is carried out in a heat exchanger. Independent claims are also included for: (1) Reactor for carrying out the process; and (2) Process for scaling up a reactor.
