Abstract

a. Le brevet principal prévoit que l'on introduit dans une quantité d'eau placée au préalable dans un récipient, on introduit les solutions de ferrocyanures en même temps que la solution de sels ferreux, mélange le mieux possible pendant la précipitation, puis traite par les procédés connus pour obtenir le bleu de Prusse. b. D'aprés le nouveau perfectionnement les quantités de sels de potassium que l'on ajoute pendant ou après la précipitation de la pâte blanche peuvent s'abaisser à moins de 1 mole jusqu'à 0,2 mole, ou se monter à plus de 3 moles jusqu'à moles par mole de ferrocyanure. c. Application à la fabrication de pigments minéraux.at. The main patent provides that one introduces into a quantity of water placed beforehand in a container, the solutions of ferrocyanides are introduced at the same time as the solution of ferrous salts, mixing as best as possible during the precipitation, then treated with known processes for obtaining Prussian blue. b. According to the new improvement, the quantities of potassium salts which are added during or after the precipitation of the white paste can drop to less than 1 mole up to 0.2 mole, or amount to more than 3 moles to moles per mole of ferrocyanide. vs. Application to the manufacture of inorganic pigments.
