A process for preparing isocyanates in the gas phase, in which the mixing of the reactants and thus the reaction conditions are significantly improved by means of hydrodynamic measures such as increasing the turbulence of the feed stream in the central nozzle. As a consequence, the necessary residence time in the reactor and thus the length of the reactor are reduced and the formation of polymeric by-products which lead to caking in the reactor and a shortening of the operating period of the reactors is avoided.

The invention relates to a method and a device for throwing balls with specific throwing parameters with the aid of a pendulum. The device consists of a pendulum having a free end which is suspended so as to be movable about an axis, characterized in that a holding device for the ball is located at the free end of the pendulum shaft and can release the ball in response to an electrical signal.
