Description

Verfahren zur Herstellung durchsichtiger Salzmassen.Process for the production of transparent salt masses.

Viele Salze lassen sich in Form von klaren Kristallmassen nur durch umständliche Kristallisations-oder Sublimadonsverfahren erhalten. Es wurde nun die Beobachtung gemacht, daß es gelingt, derartige durchsichtige Kristalle zu erhalten, wenn man aus möglichst kleinen, frisch bereiteten Salzkristallen und einer entsprechenden Menge Lösungsmittel einen halb flüssigen Brei herstellt und diesen sodann der Pressung bei einem solchen Druck unterwirft, daß das Lösungsmittel ab fließt hierbei verhindert die Anwesenheit des in reichlicher Menge vorhandenen Lösungsmittels das Eindringen von Luft in die Kristallmasse während des Preßvorganges. Es entsteht ein Produkt von paraffinartig durchscheinendem Aussehen, welches durch einen etliche Tage währenden Klärungsvorgang schließlich vollkommen durchsichtig wird. Many salts can only pass through in the form of clear crystal masses awkward crystallization or sublimadon processes obtained. It now became the Observation made that it is possible to obtain such transparent crystals, if you use the smallest possible, freshly prepared salt crystals and a corresponding one Amount of solvent produces a semi-liquid slurry and then pressing it subjects at such a pressure that the solvent thereby prevents it from flowing off the presence of the abundant solvent, the penetration of air into the crystal mass during the pressing process. A product is created of a paraffin-like, translucent appearance, which lasted for several days Clearing process finally becomes completely transparent.

Es ist zwar schon bekannt, Preßkörper aus feuchten Salzen herzustellen und auf diese Weise Erzeugnisse von hoher Dichte und Haltbarkeit zu erzeugen. Aber es handelt sich dabei immer um trübe, steinartige Massen. It is already known to produce pressed bodies from moist salts and thus to produce products of high density and durability. but it is always cloudy, stone-like masses.

Beispiel. Example.

Es wird ein feinkristallinischer Niederschlag von Salmiak durch Abschrecken einer heiß gesättigten Lösung dargestellt. Dieser wird mit einer reichlichen Menge Lösungsmittel zu einem Kristallschlamm zerrieben. A finely crystalline precipitate of ammonia is formed by quenching a hot saturated solution. This one comes with an ample amount Solvent pulverized to a crystal sludge.

Der Kristallschlamm wird in eine Matrize gefüllt, unter allmählicher Drucksteigerung zunächst 4as Lösungsmittel abgepreßt und das Preßstück schließlich mit ISOOkg pro Quadratzentimeter belastet. Das entstehende Produkt sieht aus wie Paraffin und wird im Verlauf einiger Tage durchsichtig.The crystal slurry is poured into a die, gradually Pressure increase initially squeezed 4as solvent and finally the pressed piece loaded with ISOOkg per square centimeter. The resulting product looks like Paraffin and becomes transparent over the course of a few days.

PATENT-ANSPRUCH : Verfahren zur Herstellung durchsichtiger Salzmassen, dadurch gekennzeichnet, sodaß man fein verteiltes Salz mit einer solchen Menge Lösungsmittel verrührt, daß eine breiartige Masse entsteht, und sodann einem derartig hohen Druck aussetzt, daß das gesamte Lösungsmittel abgepreßt wird. PATENT CLAIM: Process for the production of transparent salt masses, characterized in that one finely divided salt with such an amount of solvent stirred, that a pulpy mass is formed, and then such a high pressure exposes all of the solvent to be squeezed out.
