Description

meßfiüssigkeit. Es wurde gefunden, daß sich flüssige Triarylphosphate, z.B. flüssige Trikresylphosphate oder deren Gemische oder die gemischten Ester, wie sie nach den Patentschriften 348628 und 3a5629 erhalten werden können, besonders vorteilhaft als Meßflüssigkeit, d. h. als indifferentes Zwischenglied bei Messungen in den verschiedenen Apparaten, wie Flüssigkeitsmanometern, nassen Gasmessern, Zugmessern, Druckmessern usw., verwenden lassen. Die Vorteile ihrer Verwendung gegenüber den bisher üblichen Meßflüssigkeiten bestehen vor allem in ihrer chemischen Indifferenz und Reinheit, dem Mangel jeglichen Teer- und Schwefelgehaltes, in dem hohen Flamm- und Brennpunkt, dem niedrigen Gefrierpunkt, der Unvermischbarkeit mit Mineralölen und Wasser und in dein hohen spezifischen Gewicht, das größer ist als das des Wassers. Hierdurch wird erreicht, daß ein Emulgieren mit Wasser bzw. sich bildendem Kondenswasser vermieden wird. Infolge des spezifischen Gewichtes wird die Meßflüssigkeit durch Wasser nicht verdrängt. Der niedere Gefrierpunkt und die dabei verhältnismäßig geringe Viskosität der flüssigenTriarylphospbate machen überhaupt bei verschiedenen Meßgeräten die Messung im Winter erst möglich, da das Einfrieren und Beschlagen des Schauglases hier vermieden wird.measuring fluid. It has been found that liquid triaryl phosphates, e.g. liquid tricresyl phosphates or their mixtures or the mixed esters, as can be obtained according to patents 348628 and 3a5629, especially advantageous as measuring liquid, d. H. as an indifferent link in measurements in the various devices, such as liquid manometers, wet gas meters, draft meters, Have pressure gauges etc. used. The advantages of their use over the Hitherto customary measuring fluids consist primarily of their chemical indifference and purity, the lack of any tar and sulfur content, in the high flame and focus, the low freezing point, immiscibility with mineral oils and water and your high specific gravity, which is greater than that of water. This ensures that emulsification with water or condensation water that forms is avoided. Due to the specific gravity, the measuring liquid is through Water not displaced. The low freezing point and the relatively low one Viscosity of the liquid Triarylphosphbate make at all with different measuring devices The measurement is only possible in winter because the sight glass freezes and steams up is avoided here.

Die chemische Indifferenz der Meßflüssigkeit ist so groß, daß sie auch zur Messung von Kohlenoxydgasen, Sauerstoff und Ozon Verwendung finden kann, ohne daß sie dabei angegriffen wird.The chemical indifference of the measuring liquid is so great that it can also be used to measure carbon dioxide gases, oxygen and ozone, without being attacked.
