<p>The invention relates to a process for aldehydes acetaldol condensations by multi-phase reactions in a hollow reactor, which consists in that the continuous phase comprises the catalyst, and the disperse phase comprises at least one aldehyde and the reactor stress factor B is at least 0.8, so that, when operating in ascendant flux, the flooding point is exceeded, and when operating in descendant flux, the reactor is complete, thus there being provided the reactor operation above the point where it would operate in fluidized bed.</p> |
