Es wurde überraschenderweise gefunden, daß die so entstehenden Produkte eine erhebliche bakterizide Wirkung besitzen, besonders gegen gtampositive, aber auch in durchaus vertretbaren Konzentrationen gegen gramnegative Organismen. 'As is well known, phosphorus pentoxide reacts with trialkyl phosphites, trialkyl phosphates, mono- and dialkyl phosphoric acids or dialkyl ether. It was surprisingly found that so resulting products have a significant bactericidal effect, especially against gtampositive, but also in acceptable concentrations against gram-negative organisms. '

The condensation products mentioned are produced by adding the necessary amount of phosphorus pentoxide to a solution of the mono-, di- or trialkyl phosphites or alkyl phosphates or mixtures thereof in an inert solvent at relatively low temperatures.

As indifferent ίοβμ ^ βητίΐίεί 1 , for example, low molecular weight chlorinated aliphatic hydrocarbons such as perchlorethylene are suitable. vein .chloroform. .
Eine Richtvorschrift für die Herstellung von n-Hexylpolyphosphorsäureestern sei ^nachstehend gegeben: : ίA straightening method for the preparation of n-Hexylpolyphosphorsäureestern is given below ^:: ί
A. Zu 100 Gewichtsteilen eines Gemisches von Mono- und Dihexylphosphorsäureister (1:1) und 125 Gewichisteilen Perchloräthylen als Verdünnungsmittel werden in eineih mit Rückflußkühler und Thermometer versehenen Rührkolben unter Feuchtigkeitsausschltiß und gleichzeitigem ; gutem Rühren 25 Gewichtsjteile Phosphorpentoxyd in kleinen Portionen eingetragen. Nach beendeter Zugabe wird ι das Reaktionsgemisch dann über Nacht bei 45 bis 50° C bis zur vollständigen Auflösung ; des Phosphorpentoxyds stehengelassen. Sollten in jder Lösung etwa noch geringe Anteile von: nicht in Reaktion getretenem Phosphorpentoxyd vorhanden sein, kann die Lösung des Polyphosphorsäure-n-hexylesters zentrifugiert werden. :A. To 100 parts by weight of a mixture of mono- and dihexylphosphoric acid ester (1: 1) and 125 parts by weight of perchlorethylene as a diluent are in a row with a reflux condenser and Mixing flask provided with a thermometer with exclusion of moisture and at the same time; good stirring 25 parts by weight of phosphorus pentoxide in small portions registered. After the addition has ended, the reaction mixture is then kept at 45 to 50 ° C. overnight until complete dissolution; of phosphorus pentoxide ditched. Should there still be small amounts of: not reacted in each solution If phosphorus pentoxide is present, the solution of the polyphosphoric acid n-hexyl ester can be centrifuged will. :

Unter starker Wärmetönung !tritt die Reaktion ein. Durch Kühlung sorgt nian dafür, daß die Temperatur des Reaktionsgemisches 5Ö°C nicht übersteigt. Sobald die Gesamtmenge · des Phosphorpentoxydes eingetragen ist, wird das Reaktionsgemisch noch weitere 2 Stunden ,auf 5O0C erwärmt, wobei alles Phosphorpentoxyd in Lösung geht. Die erhaltene Lösung wird anschließend durch einen Druckfilter filtriert und das als Verdünnungsmittel zugesetzte Chloroform bei 5O0C im Vakuum BakterizideB. 85 parts by weight of phosphorus pentoxide are entered in the apparatus described above with exclusion of moisture with simultaneous good stirring in small portions in a 'mixture of 200 parts by weight of n-hexyl phosphite urjd 100 parts by weight of chloroform. The reaction occurs with a strong warming! By cooling, Nian ensures that the temperature of the reaction mixture does not exceed 50 ° C. Once the total amount is entered · the Phosphorpentoxydes, the reaction mixture for a further 2 hours, warmed to 5O 0 C, with all phosphorus pentoxide dissolves. The solution obtained is subsequently filtered through a pressure filter and the added diluent chloroform at 5O 0 C in vacuo bactericides
