Zusammenfassung:1. A process for controlling the temperature of exothermic reactions by superheating steam, characterized in that steam as a cooling medium is removed from a constant pressure heat accumulator filled with boiling water and positioned apart from the reaction chamber and is guided by force through the reaction chamber in several cycles, is superheated there and is then recooled after each cycle in the heat accumulator by the indirect evaporation cooling, whereby the steam is maintained at constant pressure in the heat accumulator the number of superheating and recooling cycles being selected such that the ratio of the total of the enthalpy differences of the recooling stages to the enthalpy difference between the saturated steam and feed water supplied is at least 1.1.
