Von den zahlreichen Kampferersatzmitteln, die in der letzten Zeit aufgefunden wurden, sind es in erster Linie die Ester der Phosphorsäure, welche die Verbrennbarkeit der mit ihnen hergestellten zelluloidartigen Massen in ganz merklicher Weise herabsetzen.Of the numerous camphor substitutes that have recently been discovered, It is primarily the esters of phosphoric acid which increase the combustibility of the with them reduce produced celluloid-like masses in a very noticeable manner.

Für den Fachmann ist diese Eigenschaft derFor the person skilled in the art, this property is the

die Phosphorsäure bezw. deren Salze als verbrennungshindemde Mittel schon lange bekannt sind.the phosphoric acid respectively. their salts as burn-inhibitors Means have long been known.

Wenn die neutralen Phosphorsäureester der Phenole, Kresole und Naphtole die Verbrennung der zelluloidartigen Massen noch nicht in ganz befriedigender Weise herabsetzen, so liegt dies daran, daß in diesen Verbindungen die Phosphorsäure im Verhältnis zu den organischen Substituenten nur einen geringen Teil ausmacht.When the neutral phosphoric acid esters of the phenols, cresols and naphthols start the combustion If the celluloid-like masses are not yet reduced in an entirely satisfactory manner, this is the case the fact that in these compounds the phosphoric acid in relation to the organic substituents only makes up a small part.

Es ist nun gelungen, durch Einführung anao derer Phosphorsäurederivate, und zwar solcher, die größere Mengen Phosphorsäure enthalten, in die zelluloidartigen Massen deren Verbrennung noch weiter herabzusetzen. Diese Verbindungen sind die gemischten Ester der Phosphorsäure, die sich durch Eintritt von Alkohol einerseits und Phenolen, Kresolen oder Naphtolen andererseits" 'bilden.'' ': '' ''' "IIt has now been possible, by introducing other phosphoric acid derivatives, namely those which contain large amounts of phosphoric acid, to reduce their combustion even further in the celluloid-like masses. These compounds are the mixed esters of phosphoric acid which are formed by the entry of alcohol on the one hand and phenols, cresols or naphthols on the other. ''' : '''''"I.

Sie lösen sich leicht in Alkohol, Äther, Aceton u. dgl. und sind unlöslich in Wasser.They dissolve easily in alcohol, ether, acetone and the like and are insoluble in water.

Als Kampferersatz angewendet, ist es übrigens nicht erforderlich, genau charakterisierte chemische Individuen zu verwenden, sondern es können beliebige Gemische zur Anwendung kommen.Incidentally, when used as a substitute for camphor, it is not necessary to be precisely characterized chemical individuals to use, but any mixtures can be used come.

Die neuen Ester zeichnen sich gegenüber den Phenol-, Kresol- und Naphtolphosphaten noch dadurch vorteilhaft aus, daß sie die Nitrozellulose noch erheblich leichter zu lösen vermögen.The new esters stand out from the phenol, cresol and naphthol phosphates still advantageous in that they make the nitrocellulose much easier to solve capital.

Beispiele:Examples:

ι. 100 kg Nitrozellulose werden mit 50 kg Diphenylphosphorsäureäthylester event, unter Zuhülfenahine eines Lösungsmittels für den Ester gemischt und in der bei der Zelluloidfabrikation üblichen Weise weiter verarbeite!.ι. 100 kg of nitrocellulose are 50 kg Diphenylphosphorsäureäthylester event, with Zuhülfenahine a solvent for the Esters mixed and processed in the usual way in celluloid manufacture!

2. loo kg Nitrozellulose werden mit 45 kg Kresylphosphorsiiuredimethylester wie unter 1. angegeben gemischt und weiter verarbeitet.2. 100 kg of nitrocellulose are mixed with 45 kg of dimethyl cresylphosphorate as in 1. indicated mixed and further processed.
