Formation cristalline mixte contenant du molybdène.
La présente invention est relative à un procédé nouveau et perfectionné pour la production industrielle de formations cristallines mixtes contenant du plomb et du molybdène, et elle concerne plus particulièrement un procédé plus économique que ceux employés jusqu'ici.
On a décrit de façon détaillée ces formations cristal- lines mixtes dans l'ouvrage "Gmelin's Handbook of Organic Chemistry", volume 53, 8ème. édition (1935), ainsi que dans le brevet allemand N 558.673 de la Société I. G. Farbenin- dustrie A.G. et dans un article de Jaeger et Germs paru dans la "Zeitschrift für Anorganische Chemie", vol.119 (I921), page 165, mais selon ces procédés connus jusqu'à présent on
<Desc/Clms Page number 2>
produisait les formations cristallines mixtes par la réaction de molybdates et d'autres radicaux avec de l'acétate ou du nitrate de plomb, ce qui implique nécessairement la prépara- tion, la concentration et la purification du sel de plomb.
Suivant la présente invention, on prépare les forma- tions cristallines mixtes en acidifiant au moyen d'un excès d'acide chlorhydrique une solution d'un molybdate soluble et une ou plusieurs substances formant des sels de plomb insolubles et en ajoutant ensuite une boue de litharge à cette solution acide en excès. L'acide chlorhydrique dissout la litharge pour former un chlorure de plomb qui réagit en- suite avec le molybdate et avec le sulfate, chromate, tungsta- te, vanadate, phosphate, sélénate, titanate et/ou borate pour former un produit cristallin mixte, la réaction étant achevée en faisant bouillir la solution.
On prend le molybdène, de préférence, sous forme de solution de molybdate de sodium et on y ajoute l'autre sel ou acide. On peut employer l'un ou l'autre de ces radicaux selon le produit qu'on veut obtenir, mais le procédé s'ap- plique en substance de manière générale à la production de systèmes binaires, ternaires ou quaternaires de cristaux mixtes.
Après avoir achevé la réaction par ébullition on peut éliminer de la liqueur les cristaux mixtes par décan- tation ou filtration, et après séchage ils sont prêts à tout traitement ultérieur qui peut être nécessaire pour l'usage auquel on les destine.

Mixed crystal formation containing molybdenum.
The present invention relates to a new and improved process for the industrial production of mixed crystal formations containing lead and molybdenum, and more particularly relates to a more economical process than those employed heretofore.
These mixed crystal formations have been described in detail in "Gmelin's Handbook of Organic Chemistry", volume 53, 8th. edition (1935), as well as in German patent N 558,673 of the company IG Farbenindustrie AG and in an article by Jaeger and Germs in the "Zeitschrift für Anorganische Chemie", vol.119 (I921), page 165, but according to these methods known until now,
<Desc / Clms Page number 2>
produced the mixed crystal formations by the reaction of molybdates and other radicals with lead acetate or nitrate, which necessarily involves the preparation, concentration and purification of the lead salt.
According to the present invention, the mixed crystal formations are prepared by acidifying with an excess of hydrochloric acid a solution of a soluble molybdate and one or more insoluble lead salt-forming substances and then adding a slurry of. litharge to this acidic solution in excess. Hydrochloric acid dissolves the litharge to form lead chloride which then reacts with molybdate and with sulfate, chromate, tungstate, vanadate, phosphate, selenate, titanate and / or borate to form a mixed crystalline product, the reaction being completed by boiling the solution.
Molybdenum is preferably taken as a sodium molybdate solution and the other salt or acid is added thereto. Either of these radicals can be used depending on the product desired, but the process is generally applicable to the production of binary, ternary or quaternary mixed crystal systems.
After the reaction has been completed by boiling, the mixed crystals can be removed from the liquor by decantation or filtration, and after drying they are ready for any further processing which may be necessary for their intended use.
