Description

Trockenstoffe Es wurde gefunden, daB Mischungen organischer, Nitrogruppen enthaltender Stickstoffbasen und bekannter metallhaltiger Trocknungsbeschleuniger ausgezeichnete Trockenstoffe für trocknende Öle sind.Drying agents It has been found that mixtures of organic, nitro groups containing nitrogen bases and known metal-containing drying accelerators are excellent drying agents for drying oils.

Geeignete organische, Nitrogruppen enthaltende Stickstoffbasen sind beispielsweise nitrierte Amine, z. B. Nitranilin, Nitronaphthylamin:e, Nitrohenzimidazole, Nitroindazole, Nitroguanidin wie auch Nitrogruppen. enthaltende Schiffsche Basen, z. B. solche aus p-Nitranilin und Benzaldehyd, Zimtaldehyd, Crotonaldehyd u. dgl.oder aus Anilin und Nitrob@enzaldehyden oder Nitrozisntaldehyden. Unter organischen, Nitrogruppen enthaltenden Stickstoffbasen sollen nicht organische Farbstoffbasen, die Nitrogruppen enthalten, verstanden werden. Beispielsweise trocknet Leinöl bei normalen Temperatur-, Feuchtigkeits- und Lichtverhältn ismen nach Zusatz von o, 5 % Benzaldehydp-nitranil und o,33 % Mangannaphthenat in der gleichen Zeit auf wie bei Zusatz von o,66% Mangannaphthenatoder 0,33% Kobaltnaphthenat allein. Das Verfahren ermöglicht es somit, die gleich gute Wirkung der teuren Kobalttrockenstoffe mit denn wahl.feüeren Mangantrockenstoffen durch Zusatz der genannten, Nitrogruppen enthaltenden organischen Stickstoffbasen zu .erreichen oder die Menge des Mangantrockenstoffes auf die Hälfte herunterzudrücken.Suitable organic nitrogen bases containing nitro groups are for example nitrated amines, e.g. B. Nitraniline, Nitronaphthylamine: e, Nitrohenzimidazole, Nitroindazole, nitroguanidine as well as nitro groups. containing Schiff bases, z. B. those from p-nitroaniline and benzaldehyde, cinnamaldehyde, crotonaldehyde and the like. Or from aniline and nitrob @ enzaldehydes or nitrozisntaldehydes. Under organic, Nitrogen bases containing nitro groups should not be organic dye bases, which contain nitro groups can be understood. For example, linseed oil dries up normal temperature, humidity and light conditions after adding o, 5% benzaldehyde p-nitranil and o, 33% manganese naphthenate in the same time as with addition of 0.66% manganese naphthenate or 0.33% cobalt naphthenate alone. The procedure thus enables the same good effect of the expensive cobalt dry matter with because Wahl.feüeren manganese dry matter by adding the mentioned nitro groups containing organic nitrogen bases or the amount of manganese dry matter press down to half.

Die Nitrogruppen enthaltenden organischen Stickstoffbasen erhöhen auch die Trockenwirkung solcher metallhaltiger Trockenstoffe, die an sich nur eine geringe Beschleunigung auf die Trocknung auszuüben vermögen. So besitzen Eisenverbindungen, die für manche trocknenden Öle nur sehr schwach wirksam sind, nach Zusatz von o,2 bis 0,5% Beuz,#" aldehyd-p-nitranil oder Zimtaldehyd-p-nitra bezogen auf die Menge des trocknenden Öres;: ein recht hohes Beschleunigungsvermögen für die Trocknung und werden damit zu praktisch brauchbaren Trockenstoffen.Increase the organic nitrogen bases containing nitro groups also the drying effect of such metal-containing drying agents, which in itself is only one low acceleration able to carry out drying. So have iron compounds that are only very weakly effective for some drying oils are, after adding 0.2 to 0.5% Beuz, # "aldehyde-p-nitranil or cinnamaldehyde-p-nitra based on the amount of drying ore ;: a very high acceleration capacity for drying and thus become practically usable drying agents.

Überdies wird bei Verwendung der genannten Nitrogruppen enthaltenden Basen mit bekannten metallhaltigen Trockenstoffen die oft recht beträchtliche Abhängigkeit der Trocknungsgeschwindigkeit von der Luftfeuchtigkeit, wie sie bei Verwendung der metallhaltigen Trockenstoffe allein beobachtet wird, ganz wesentlich vermindert. Dadurch wird die Sicherheit, daß man auch bei verschiedener Luftfeuchtigkeit die gewünschte Trockenzeit und Wirkung erzielt, bedeutend erhöht. Auch der Einfluß der Temperatur ist bei den genannten Trockenstoffgemischen geringer als bei Verwendung von metallhaltigen Trockenstoffen allein.In addition, when using the mentioned nitro groups Bases with known metal-containing desiccants often have a considerable dependency the drying speed depends on the humidity, as it is when using the metal-containing dry matter alone is observed, very significantly reduced. This ensures that you can also use the Desired drying time and effect achieved, significantly increased. Also the influence of the The temperature is lower with the mentioned dry substance mixtures than with use metal-containing dry matter alone.

Die in den folgenden Beispielen angegebenen Teile sind Gewichtsteile.The parts given in the following examples are parts by weight.

Beispiel i i ooo Teile rohes Leinöl werden mit 4 Teilen Benzaldehyd-p-nitranil und 3,3 Teilen Mangannaphthenat versetzt. Die dabei erhaltene Lösung stellt einen Firnis dar, der wenig feuchtigkeitsempfindlich ist und etwa in der gleichen Zeit auftrocknet, wie wenn er o,66ü/o Mangannaphthenat gelöst enthielte.EXAMPLE 10000 parts of crude linseed oil are mixed with 4 parts of benzaldehyde-p-nitranil and 3.3 parts of manganese naphthenate were added. The solution obtained is a Varnish that is not very sensitive to moisture and takes about the same time dries up as if it contained 0.66% dissolved manganese naphthenate.

Beispiel z Ein Leinölfirnis, der 5 Teile Zimtaldehydp-nitranil und 1,7 Teile Kobaltnaphthenat auf iooo Teile Leinöl enthält, liefert Anstriche, die etwa in der gleichen Zeit trocknen, wie wenn o,33% Kohaltnaphthenat allein zuge-# etzt worden wären.Example z A linseed oil varnish containing 5 parts of cinnamaldehyde p-nitranil and 1.7 parts of cobalt naphthenate per 1,000 parts of linseed oil provides paints that dry in about the same time as if 0.33% carbon naphthenate had been added alone.

Beispiel 3 io Teile Eisen (III)-naphthenat und 4 bis 5 Teile Zimtaldehyd-p-nitranil werden in iooo Teilen Leinöl gelöst. Ein daraus hergestellter Anstrich trocknet in 15 Stunden, während ein vergleichsweise hergestellter Anstrich mit i % Eisennaphthenat ohne den Zusatz von Zimtaldehyd-p-nitranil erst nach etwa 3 Tagen trocken ist.Example 3 10 parts of iron (III) naphthenate and 4 to 5 parts of cinnamaldehyde p-nitranil are dissolved in 1,000 parts of linseed oil. A coating made from it dries in 15 hours, while a comparatively produced paint with 1% iron naphthenate without the addition of cinnamaldehyde-p-nitranil is only dry after about 3 days.

Beispiel ¢ Man stellt einen Leinölfirnis her, der i ooo Teile Leinöl, 6 Teile Mangannaphthenat und 3o Teile Benzaldehyd-p-nitranil enthält. Die Trackengeschwindigkeit bei i8' beträgt in trockener und in mit Wasserdampf gesättigter Luft 4i/2 Stunden.Example ¢ A linseed oil varnish is made that contains 10000 parts of linseed oil, Contains 6 parts of manganese naphthenate and 3o parts of benzaldehyde-p-nitranil. The track speed at i8 'is 4½ hours in dry air and in air saturated with water vapor.

Die günstige Wirkung des Benzaldehydp-nitranils geht daraus hervor, daß ein Leinölfirnis ohne diesen Zusatzstoff, aber sonst von der gleichen Zusammensetzung wie oben angegeben, erst nach 5 Stunden in trockener Luft anzuziehen beginnt, während er in feuchter Luft nach 5 Stunden noch die gleiche Beschaffenheit hat wie kurz nach dein Aufstreichen.The beneficial effect of benzaldehyde p-nitranil results from that a linseed oil varnish without this additive, but otherwise of the same composition as stated above, begins to attract only after 5 hours in dry air while in moist air after 5 hours it still has the same properties as it did shortly after your painting.
