KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei Benutzung der bisherigen festen Siccative, die grofsentheils aus einem Gemisch von Gyps mit borsaurem Manganoxydul bestehen, zeigt sich der Uebelstand, dafs die damit versetzten Farben schon nach kurzer Zeit einen nicht unbedeutenden Niederschlag absondern. Der dadurch sich bildende Bodensatz macht in den meisten Fällen einen gröfseren Farbenrest unbrauchbar und bedeutet somit einen ansehnlichen Verlust. Aufserdem dunkeln die mit solchen Siccativen versetzten Farben — hauptsächlich die helleren — mehr oder weniger nach.When using the previous solid siccatives, which for the most part consist of a mixture of If there are gypsies with boric acid manganese oxide, the problem is shown that they are mixed with it Colors give off a not insignificant precipitate after a short time. The sediment that forms as a result makes in most cases a larger residual color is unusable and thus means a sizable loss. In addition, the colors offset with such siccatives darken - mainly the lighter ones - more or less after.
Die vorliegende Erfindung betrifft ein Siccativ, welches die genannten Uebelstände beseitigt.The present invention relates to a siccative which eliminates the above-mentioned inconveniences.
Das neue Siccativ wird erhalten, indem man aus einer Lösung, welche primäres Calciumneben primärem Magnesiumphosphat enthält, mittels eines Alkalisalzes ein Gemisch von secundärem Calcium- mit secundärem Magnesiumphosphat ausfällt.The new Siccativ is obtained by converting from a solution which contains primary calcium in addition to contains primary magnesium phosphate, a mixture of secondary calcium phosphate with secondary magnesium phosphate by means of an alkali salt fails.
Beispielsweise werden ca. 70 Theile saurer phosphorsaurer Kalk und ca. 20 Theile saure phosphorsaure Magnesia mit einer äquivalenten Menge kohlensaurem Natron ausgefällt.For example, about 70 parts are acidic phosphoric acid lime and about 20 parts are acidic phosphoric acid magnesia precipitated with an equivalent amount of carbonate of soda.
Der Vorgang ist folgender: Ca (PH2 OJ2 + Na2 C O3 = Ca H PO4 + Na2 H P O4 + H2 O + C O2 (mit analoger Anwendung für das Magnesiasalz).The process is as follows: Ca (PH 2 OJ 2 + Na 2 C O 3 = Ca H PO 4 + Na 2 HP O 4 + H 2 O + C O 2 (with an analogous application for the magnesia salt).
Der sich hierbei ausscheidende innig gemischte Niederschlag von phosphorsaurer Kalkmagnesia ist von äufserster Feinheit und bildet nach dem Trocknen bei mäfsiger Temperatur ein helles hygroskopisches Pulver, welches hervorragende trocknende Eigenschaften besitzt. Durch eventuellen Zusatz eines Mangansalzes, etwa ίο Theilen reinem borsauren Manganoxydul, kann die Trockenfähigkeit noch erhöht werden.The intimately mixed precipitate of phosphoric acid lime magnesia which separates out here is of the utmost delicacy and forms after drying at a moderate temperature a light, hygroscopic powder with excellent drying properties. By possible addition of a manganese salt, about ίο parts of pure boric acid manganese oxide, the drying ability can be increased.
