<Desc/Clms Page number 1>
Nouveau procédé pour la fabrication de sulfates alcalino-ter- reux et de couleurs diverses en partant des sulfates alca- lino-terreux naturels.
Cette invention a pour objet un procédé pour la fa- brioation directe de sulfates alcalino-terreux et de couleurs diverses en partant directement des sulfates alcalino-terreux naturels.Ces produits ont été obtenus jusqu'à présent,soit à titre de sous-produits de fabrication,soit par précipitation par voie chimique en passant par de multiples réactions par- fois assez compliquées.
Selon l'invention,le même but est réalisé d'une façon beaucoup plus simple lorsque les sulfates alcalino-terreux naturels réduits en poudre plus ou moins fine sont dissous d'abord dans des solvants appropriés,par exemple,dans l'acide sulfurique concentré à chaud,après quoi les sulfates alcalino- terreux ohimiquement purs sont précipités de la solution par un moyen physico-chimique quelconque,par exemple par simple hydrolyse ou par électro-osmose.
<Desc/Clms Page number 2>
Pour faciliter la dissolution des matières à traiter dans le dissolvant,on peut aussi faire usage de catalyseurs métalliques ou métalloïdiques solides ou gazeux.Ces cataly- seurs peuvent même être présents dans les roches naturelles soumises au traitement,tels les ions cuivre,chrome,fer,etc.
La présence de ces ions dans la solution de sulfates alcalino-terreux,en outre qu'elle facilite la dissolution, donne encore naissance à un phénomène d'absorption en ce sens que le précipité obtenu,autrement parfaitement blanc,prend une certaine coloration,dont la teinte et la nuance varient selon la nature de l'ion présent et son degré de concentration.
Les précipités colorés obtenus de cette sorte se prê- tent à la préparation de couleurs à l'huile parfaitement sta- bles et la plupart indécomposables par les agents chimiques.
Comme catalyseurs pour augmenter la solubilité des sul- fates alcalino-terreux naturels,on pourrait employer:SO3,SO2, NO2, etc. puis, pour l'obtention de précipités colorés:les ions
EMI2.1
vanadium, cuivre .cadmium, zinc, sodium,potassium, ammonium,fer, chrome ,aluminium, cobalt ,nickel ,manganèse ,magnésium, etc.
Exemples.- 1)16 partie aile sulfate de baryum naturel réduit en poudre aussi fine que possible sont dissoutes à chaud dans 100 parties d'acide sulfurique fumant,c'est-à-dire contenant le catalyseur SO3.
On ajoute à cette solution de l'eau,ou mieux encore de la glace pour éviter un échauffement trop intense, ce qui a pour effet de précipiter le sulfate de baryum chimiquement pur et coloré si l'acide sulfurique contenait un ion ou corps co- lorant.La précipitation pourrait s'opérer aussi par voie é- lectrique (électro-osmose).
Peu importe,dans ce procédé,que la roche naturelle
<Desc/Clms Page number 3>
soit polluée par des impuretés en quantité plus ou moins grandes,car les unes vont se dissoudre dans la solution (Fe,
Mn, Cu) tandis que les autres,telle la silice,vont rester insolubles.
3)Au. lieu d'être dissout dans l'acide sulfurique fu- mant,le sulfate de baryum pourrait aussi être dissout dans l'anhydride sulfurique directement.
3)Le sulfate de baryum pourrait aussi être broyé di- rectement avec de l'acide sulfurique concentré.
4)Une fusion alcaline pourrait être préparée avec les matières à traiter et cette fusion pourrait être versée dans de l'eau,ce qui fera précipiter le sulfate alcalino-terreux.
5)Le catalyseur pourrait être un ion métallique ou métalloïdique, ce qui fera obtenir des préoipités colorés.
La couleur de ces précipités pourrait d'ailleurs,par oaloination,être changée en une autre qui sera celle de l'oxy- de de l'ion métallique absorbé par le pigment précipité.
Ainsi avec l'ion Cr.. heptavalert,on obtient un pré- cipité de sulfate de baryum coloré en jaune.Si ce précipité est calciné,il change sa couleur en vert, phénomène dû à la for. mation de Cr2O3 vert.Ce pigment est insoluble dans les acides.
La précipitation des sulfates alcalino-terreux pourra se faire aussi avec une émulsion en suspension de terres di- verses entrant dans la composition des pigments,tels que des kaolins,argile,oxydes de Titane,etc.

New process for the production of alkaline earth sulphates and various colors starting from natural alkaline earth sulphates.
This invention relates to a process for the direct manufacture of alkaline earth sulphates of various colors starting directly from natural alkaline earth sulphates. These products have hitherto been obtained either as by-products of manufacture, or by chemical precipitation via multiple reactions which are sometimes quite complicated.
According to the invention, the same object is achieved in a much simpler way when the natural alkaline earth sulphates reduced to a more or less fine powder are first dissolved in suitable solvents, for example in concentrated sulfuric acid. hot, after which the ohimically pure alkaline earth sulphates are precipitated from the solution by any physicochemical means, for example by simple hydrolysis or by electro-osmosis.
<Desc / Clms Page number 2>
To facilitate the dissolution of the materials to be treated in the solvent, it is also possible to use solid or gaseous metal or metalloidal catalysts. These catalysts can even be present in natural rocks subjected to the treatment, such as copper, chromium, iron ions. , etc.
The presence of these ions in the solution of alkaline earth sulphates, in addition to facilitating the dissolution, still gives rise to an absorption phenomenon in the sense that the precipitate obtained, otherwise perfectly white, takes on a certain color, of which the hue and shade vary depending on the nature of the ion present and its degree of concentration.
The colored precipitates obtained in this way are suitable for the preparation of perfectly stable oil colors, most of which cannot be decomposed by chemical agents.
As catalysts for increasing the solubility of natural alkaline earth sulphates, the following could be used: SO3, SO2, NO2, etc. then, to obtain colored precipitates: the ions
EMI2.1
vanadium, copper, cadmium, zinc, sodium, potassium, ammonium, iron, chromium, aluminum, cobalt, nickel, manganese, magnesium, etc.
Examples - 1) 16 wing part natural barium sulphate reduced to powder as fine as possible are dissolved hot in 100 parts of fuming sulfuric acid, that is to say containing the catalyst SO 3.
To this solution is added water, or better still ice to avoid too intense heating, which has the effect of precipitating the chemically pure and colored barium sulphate if the sulfuric acid contained an ion or body co- lorant.The precipitation could also take place electrically (electro-osmosis).
It does not matter, in this process, that the natural rock
<Desc / Clms Page number 3>
is polluted by impurities in more or less large quantities, because some will dissolve in the solution (Fe,
Mn, Cu) while the others, such as silica, will remain insoluble.
3) At. Instead of being dissolved in fuming sulfuric acid, barium sulfate could also be dissolved in sulfuric anhydride directly.
3) Barium sulphate could also be ground directly with concentrated sulfuric acid.
4) An alkaline melt could be prepared with the materials to be treated and this melt could be poured into water which will precipitate the alkaline earth sulfate.
5) The catalyst could be a metal or metalloid ion, which will cause colored precipitates to be obtained.
The color of these precipitates could, moreover, by aloination, be changed to another which will be that of the oxide of the metal ion absorbed by the precipitated pigment.
Thus with the Cr .. heptavalert ion, we obtain a precipitate of barium sulphate colored yellow. If this precipitate is calcined, it changes its color to green, a phenomenon due to the forest. green Cr2O3 This pigment is insoluble in acids.
The precipitation of alkaline earth sulphates can also be carried out with an emulsion in suspension of various earths entering into the composition of the pigments, such as kaolins, clay, titanium oxides, etc.
