C. and under a pressure of from 1 to 3,000 mbar, advantageously in the presence of assistants which reduce the partial pressure, eg. water and/or methanol.

摘要： A coherent explosive gas phase in a gas/liquid reactor comprising a tubular body which is closed at the top and into which one or more jets of liquid which are fed from a liquid circulation and are directed downward, emerge from one or more nozzles located at the highest point of the reactor, and entrain a gas phase which is to be dispersed, introduce it into the liquid and finally produce complete dispersion of the gas, is avoided by a method wherein, before start-up of the liquid circulation, the inactive reactor is charged with an amount of liquid reactant such that a gas space corresponding to the subsequent gas hold-up of dispersed bubbles under operating conditions remains at the top of the reactor, this gas space is filled with a gas, at a pressure p.sub.1, which is inert under the reaction conditions, and the gaseous reactant is fed to the reactor only when, under the action of the liquid jet or jets, the inert gas has been dispersed into a hold-up of dispersed bubbles so that a coherent gas phase no longer exists.
