    • 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.
    • 在气/液反应器中的相干爆炸性气相,包括管状主体,该管状体在顶部封闭,并且从液体循环进给并被向下引导的一个或多个液体射流从该管状体中的一个或多个喷嘴出射 反应器的最高点,并且夹带待分散的气相,将其引入液体中并最终产生气体的完全分散,通过其中在液体循环启动之前的非活性的方法避免了 反应器装有一定量的液体反应物,使得在操作条件下与分散气泡的随后气体保持相对应的气体空间保持在反应器的顶部,该气体空间以压力p1填充气体, 其在反应条件下是惰性的,并且气体反应物仅在液体射流或喷射作用下被输送到反应器中时,惰性气体已经分散到分散的气泡的滞留物中,使得coh 气相不再存在。
