Description

DEUTSCHESGERMAN

Die Erfindung betrifft ein Verfahren zur Herstellung eines basischen Aluminiumchlorids, welches insbesondere zur Schweißverhinderung dient. Bei dem bisher bekannten Verfahren zur Herstellung von basischem Aluminiumchlorid handelte es sich um sogenannte »nasse Verfahren«, beispielsweise um Neutralisierung mit Basen oder mit metallischem Aluminium, Elektrolyse mit Aluminiumchloridlösungen usw., bei welchen mit Konzentrationslösungen von 15 bis 25'% Aluminiumchlorid gearbeitet wird. Für die Reeaktion ist dabei ein erheblicher Energieaufwand erforderlich. Außerdem müssen nach beendeter Reaktion große Mengen Wasser verdampft werden, um ein Erzeugnis in trockener Form zu erhalten, da eine Lagerung und ein Transport des Aluminiumchlorids nur in trockener Form möglich ist. Für die Verdampfung der verhältnismäßig großen Wassermengen ist ein weiterer, sehr beträchtlicher Energieaufwand erforderlich.The invention relates to a method for producing a basic aluminum chloride, which in particular serves to prevent perspiration. In the previously known method for producing basic aluminum chloride, it was a question of so-called "wet processes", for example neutralization with bases or with metallic aluminum, electrolysis with aluminum chloride solutions etc., in which concentration solutions of 15 to 25% aluminum chloride are used. For the reaction requires a considerable expenditure of energy. Also need to finish Reaction large amounts of water are evaporated to obtain a product in dry form, since storage and transport of the aluminum chloride is only possible in dry form. For the Evaporation of the relatively large amounts of water is another very considerable amount of energy necessary.

Diese Nachteile sind erfindungsgemäß bei einem Verfahren zur Herstellung eines insbesondere zur Schweißverhinderung dienenden basischen Aluminiumchlorids dadurch vermieden, daß Aluminiumchlorid (AlCl3-OH2O) bei einer Temperatur von 150 bis 1700C erhitzt wird, bis der Gewichtsverlust etwa 60 0Zo beträgt, worauf die Erhitzung abgebrochen wird. Bei dem erfindungsgemäßen »trockenen Verfahren« wird also als Ausgangsstoff ein kristallisiertes Aluminiumchlorid in Pulverform verwendet. Es genügt dabei, nur einen Teil des Kristallwassers und des Chlor-Wasserstoffes zu verdrängen, um so unmittelbar das gewünschte basische Aluminiumchlorid in trockener und gebrauchsfertiger Pulverform zu erhalten. Auf diese Weise ist der Energieaufwand auf ein Minimum beschränkt. Es gelingt außerdem durch das erfindungsgemäße Verfahren, ein basisches Aluminiumchlorid herzustellen, das hinsichtlich seines Hemmungseffektes auf den Schweiß und seiner Stabilität in wäßriger Lösung besondere Vorteile bietet.These disadvantages are according to the invention, avoided in a method for producing a particular serving to weld prevention basic aluminum chloride that aluminum chloride (AlCl 3 -OH 2 O) is heated at a temperature of 150 to 170 0 C, until the weight loss is about 60 0 Zo, whereupon the heating is stopped. In the “dry process” according to the invention, a crystallized aluminum chloride in powder form is used as the starting material. It is sufficient to displace only part of the water of crystallization and the chlorine-hydrogen in order to obtain the desired basic aluminum chloride immediately in dry and ready-to-use powder form. In this way, the energy consumption is kept to a minimum. The process according to the invention also makes it possible to produce a basic aluminum chloride which offers particular advantages in terms of its inhibitory effect on sweat and its stability in aqueous solution.

Die Erfindung ist in der Beschreibung an Hand eines Herstellungsbeispiels näher erläutert.The invention is explained in more detail in the description using a production example.

24,1 g Al Cl3 · 6 H2 O werden auf dem offenen Feuer in einer Porzellanschale unter einem Abzug bei einer Temperatur von 150 bis 170° C unter Umrühren erhitzt. Man erhält diese Temperatur der Masse aufrecht, bis das Gewicht des Aluminiumsalzes nur noch 9,6 g beträgt. Es ergibt sich ein weißes Pulver, das dem Aluminiumoxyd gleicht, in kaltem Wasser unlöslich, aber in siedendem Wasser löslich ist. Erforderlichenfalls kann filtriert werden. Wenn es einmal in Lösung ist, kristallisiert das gebildete basische Salz in der Kälte nicht wieder, und es muß im Wasserbad stark konzentriert werden, um Kristalle zu erhalten. Auf die gleiche Weise kann, von kristalli-Verfahren zur Herstellung
eines basischen Aluminiumchlorids24.1 g of Al Cl 3 · 6 H 2 O are heated on an open fire in a porcelain dish under a hood at a temperature of 150 to 170 ° C. while stirring. This temperature of the mass is maintained until the weight of the aluminum salt is only 9.6 g. The result is a white powder that is like aluminum oxide, insoluble in cold water, but soluble in boiling water. If necessary, it can be filtered. Once in solution, the formed basic salt does not recrystallize in the cold and it has to be concentrated strongly in a water bath in order to obtain crystals. In the same way you can, from crystalli-process to manufacture

siertem Al (N O3) 3 ausgehend, ein basisches Aluminiumnitrat hergestellt werden.based on Al (NO 3 ) 3 , a basic aluminum nitrate can be produced.

Das auf diese Weise erhaltene Produkt gibt die Nachweisreaktionen für Chlor- und Aluminiumionen. Es ist stark wasserlöslich, teilweise löslich in Äthanol und unlöslich in Toluol. Die 10%ige Lösung besitzt einen pH-Wert von 3,8 bis 4,0. Gibt man zu dieser 10%igen Lösung eine molare Lösung voni Al Cl3I · 6 H2 O, so können alle Zwischenwerte zwischen pH 1,8 und pH 3,9 hergestellt werden, das pH benötigt aber 24 Stunden zur Stabilisierung. Es ist also möglich, ein sehr aktives Sch weiß Verhinderungsmittel herzustellen, dabei aber die Acidität der Lösung so gering zu halten, daß weder die Kleider schaden nehmen noch Rötungen an der Haut auftreten können.The product obtained in this way gives the detection reactions for chlorine and aluminum ions. It is highly soluble in water, partially soluble in ethanol and insoluble in toluene. The 10% solution has a pH value from 3.8 to 4.0. Are added to this 10% solution of a molar solution voni Al Cl 3 I · 6 H 2 O, then all intermediate values between 1.8 and p H p H can be made 3.9, but the p H needs 24 hours to stabilize . It is therefore possible to produce a very active anti-swelling agent, but to keep the acidity of the solution so low that neither the clothes are damaged nor reddening of the skin can occur.
