Abstract

In the method for the chemical reaction of gaseous educts the educts are brought to reaction in a phase contact apparatus 1 in the presence of a catalytically active corrosive liquid. This corrosive liquid is delivered hydropneumatically in an intermittent cycle in the circuit from a sump vessel 4 connected to the lower end of the phase contact apparatus 1 to a supply vessel 9, connected to the upper end of the phase contact apparatus (delivery cycle), from which the corrosive liquid drains through the phase contact apparatus 1 and a connecting line 11 connected at its lower end and then collects in the sump vessel 4 (drainage cycle).
