Abstract
Process for separating and purifying condensation products suspended or dispersed in water, liquid and insoluble at high temperature and possibly tablets, characterized in that the lower area of the reaction space in which the condensation takes place is heated while the condensation product is being formed or later to a mean temperature lower than the average temperature of the entire reaction space and the temperature of the upper zone of the same space thus producing a lower layer of condensation product clearly separated from the upper water layer.
