Hydraulische Flüssigkeiten werden bekanntlich auch als Kupplungsmittel für umlaufende Maschinen oder als Betriebsmittel für hydraulische Pressen, Hebebahnen u. dgl. verwendet.It is well known that hydraulic fluids are also used as coupling agents for rotating machines or as operating equipment for hydraulic presses, lifting tracks and the like.
Für solche Flüssigkeiten werden nach den neuzeitlichen Spezifikationen (SAE 70 R 3 und SAE 71 R) hohe Wärmestabilitäten und gleichzeitig hohe Siedepunkte gefordert. Andererseits wird für hydraulische Flüssigkeiten ein solches Wasseraufnahmevermögen gewünscht, daß Spuren von Wasser den Siedepunkt praktisch nicht erniedrigen.According to the latest specifications (SAE 70 R 3 and SAE 71 R) high thermal stability and at the same time high boiling points are required. The other hand is for hydraulic Liquids such a water absorption capacity desired that traces of water the Practically do not lower the boiling point.
Die derzeit besten hydraulischen Flüssigkeiten bestehen aus Gemischen von Alkylenglykolen und Alkylenglykoläthern bzw. Kondensationsprodukten von Fettsäuren mit Alkylenglykolen oder mehrwertigen Alkoholen. Überwiegend enthalten diese Flüssigkeiten Derivate des Äthylenoxyds, welche das Wasseraufnahmevermögen dieser hydraulischen Flüssigkeiten bewirken, weil sie selbst stark hygroskopisch sind.The best hydraulic fluids currently available consist of mixtures of alkylene glycols and Alkylene glycol ethers or condensation products of fatty acids with alkylene glycols or polyvalent ones Alcohols. These liquids mainly contain derivatives of ethylene oxide, which have the ability to absorb water of these hydraulic fluids because they are themselves highly hygroscopic.
Es wurde nun gefunden, daß man hydraulische Flüssigkeiten auf Basis von Gemischen von AIkylenglykolen und Alkylenglykolderivaten mit hervorragender Thermostabilität erhält, indem man Gemische verwendet, bei denen mindestens eine Komponente als endständiges Glied der Äthylenglykolätherkette eine Propoxy- bzw. Butoxygruppe besitzt. In Fällen wie beim Polyäthylenglykol mit einem mittleren Molekulargewicht von 200 wird durch beiderseitigen Verschluß der Kette mit einem Propylenoxydrest die Thermostabilität außerordentlich verbessert.It has now been found that hydraulic fluids based on mixtures of alkylene glycols can be used and alkylene glycol derivatives having excellent thermal stability are obtained by mixing mixtures used in which at least one component is the terminal link of the ethylene glycol ether chain has a propoxy or butoxy group. In cases like polyethylene glycol with a average molecular weight of 200 is achieved by locking the chain on both sides with a propylene oxide residue the thermal stability is greatly improved.

butoxylierten Polyalkylenglykoläther und Polyalkylenglykolätherderivate erfolgt nach den bekannten Methoden.butoxylated polyalkylene glycol ethers and polyalkylene glycol ether derivatives are carried out according to the known Methods.
Die Thermostabilität der Bestandteile der neuen hydraulischen Flüssigkeiten wird bestimmt, indem man die Flüssigkeiten in einem nach SAE standardisierten Ofen bei 100° C über einen Zeitraum von beispielsweise 330 Stunden ausmißt. Die so erhaltenen Meßwerte für eine Anzahl von bekannten und von im Sinn der Erfindung modifizierten Bestandteilen von hydraulischen Flüssigkeiten sind in der anschließenden Tabelle zusammengestellt. Die Hygroskopizität wird bestimmt, indem man Petrischalen vom Durchmesser 70 mm mit etwa 2 bis 5 g der Flüssigkeit beschickt und 192 Stunden einer relativen Luftfeuchtigkeit von 80% aussetzt, bevor man mißt.The thermostability of the components of the new hydraulic fluids is determined by the liquids in an oven standardized according to SAE at 100 ° C for a period of measures 330 hours, for example. The measured values thus obtained for a number of known and of components of hydraulic fluids modified within the meaning of the invention are disclosed in the table below. The hygroscopicity is determined by Petri dishes with a diameter of 70 mm are charged with about 2 to 5 g of the liquid and one for 192 hours exposure to relative humidity of 80% before measuring.
