Description
Verfahren zur Behandlung mineralischer Carbonate mit oberflächenaktiven Stoffen Gegenstand des Hauptpatents 958 830 ist ein Verfahren zur Behandlung von natürlich vorkommendem Calciumcarbonat, insbesondere von Kreide in Form von sehr feinen Teilchen, auf die jeweils eine oder mehrere sehr fein zerteilte feste Substanzen aufgebracht werden, die durch Oberflächenkräfte auf den Calciumcarbonätteilchen festgehalten werden.Process for the treatment of mineral carbonates with surface-active substances Substances The subject of the main patent 958 830 is a process for the treatment of naturally occurring calcium carbonate, especially chalk in the form of very fine particles, each containing one or more very finely divided solid substances applied by surface forces on the calcium carbonate be held.
Als feste Substanzen wurden unter anderem die höheren Fettsäuren, wie z. B. Stearinsäure, angeführt. Die Modifizierungsstoffe werden in Mengen von 0,1 bis 40 % bei mindestens 80°C mit dem Calciumcarbonat gemahlen.As solid substances, among other things, the higher fatty acids, such as B. stearic acid. The modifiers are used in amounts of 0.1 to 40% ground with the calcium carbonate at at least 80 ° C.
In diesem Patent wurde unter Betonung des Vorteils die feste Aufbringung von höheren Fettsäuren auf natürlich vorkommende Calciumcarbonate unter Bedingungen beschrieben, unter denen die Fettsäure die Kohlensäure ersetzen kann, so daß ein Teil des Calciumcarbonats in ein Calciumsalz der verwendeten höheren Fettsäure oder Fettsäuren umgewandelt wird.In this patent, emphasis was placed on the fixed application from higher fatty acids to naturally occurring calcium carbonates under conditions described, among which the fatty acid can replace the carbonic acid, so that a Part of the calcium carbonate in a calcium salt of the higher fatty acid used or Fatty acids is converted.
Das Hauptpatent betrifft die Behandlung von natürlich vorkommenden Calciumcarbonaten, die Kreide sedimentären Ursprungs sowie kristalline Calciumcarbonate mit Saccharoidstruktur vom Typus des Marmors umfassen.The main patent concerns the treatment of naturally occurring Calcium carbonates, chalk of sedimentary origin and crystalline calcium carbonates with a saccharoid structure of the marble type.
Es wurde nun gefunden, daß man die gleichen Vorteile erzielen kann, wenn man unter den im Hauptpatent beschriebenen Bedingungen Doppelcarbonate des Calciums und Magnesiums, die in der Natur unter dem Namen Dolomit bekannt sind, behandelt. Der Mengenanteil an Calciumcarbonat im Verhältnis zu Magnesiumcarbonat in dem Dolomit ist gleichgültig.It has now been found that the same advantages can be achieved if under the conditions described in the main patent double carbonates des Calcium and magnesium, known in nature as dolomite, treated. The proportion of calcium carbonate in relation to magnesium carbonate in the dolomite is indifferent.
Auch kann man gleiche Ergebnisse erzielen, wenn man von reinem Magnesiumcarbonat ausgeht.You can also achieve the same results if you use pure magnesium carbonate goes out.
Ganz allgemein ist die in dem Hauptpatent beschriebene Behandlung als auf alle Carbonate mineralischer Art, wie z. B. Bariumcarbonat, Strontiumcarbonat, Zinkcarbonat usw., anwendbar erkannt worden. Es ist tatsächlich festgestellt worden, daß es möglich ist, die Kohlensäure dank einer Behandlung der Oberfläche der Carbonate mit höheren Fettsäuren unter den in dem Hauptpatent beschriebenen Bedingungen durch diese Säuren zu verdrängen.The treatment described in the main patent is quite general than on all carbonates of a mineral nature, such as. B. barium carbonate, strontium carbonate, Zinc carbonate, etc., has been recognized as being applicable. It has actually been established that it is possible to carbonate thanks to a treatment of the surface of the carbonates with higher fatty acids under the conditions described in the main patent to displace these acids.
