Abstract
A process for the continuous precipitation of gelatinous products, especially pigments, in finely divided form from the aqueous solutions of corresponding metallic salts, by means of acids, bases or salts, characterized in that the previous phase or aqueous preparation necessary for the precipitation, with a certain concentration of solution, is introduced into the reaction system continuously before the addition of one or both participants of the reaction, in such quantities that the reaction mixture after the addition of the precipitation components it corresponds in its composition, that is to say in the amount of the previous phase and in the quantity of the other participants of the reaction, with the optimum final values under the conditions that prevail in cases of discontinuous work.
