Description

Es wurde gefunden, daß als Schmiermittel auf
synthetischer Basis an sich bekannte Polyester, Polyäther oder Polyesteräther hervorragend zum Schmieren von mit Difluormonochlormethan betriebenen Kälteanlagen geeignet sind.
Von den Polyestern kommen vor allem diejenigen in Betracht, die keinen wesentlichen Gehalt an freien Hydroxylgruppen besitzen, d. h. insbesondere Verbindungen, wie sie durch Umsetzung
ίο von mehrwertigen Alkoholen mit Dicarbonsäuren im Unterschuß und anschließende Veresterung mit Monocarbonsäuren erhältlich sind; geeignete Polyäther und Polyesteräther sind in der französischen Patentschrift 898 269 sowie in den bekanntgemachten Unterlagen der deutschen Patentschrift 883 506 vorbeschrieben. Auch die in der britischen Patentschrift 662 650 vorbeschriebenen Esteröle sind für die hier vorgeschlagene Verwendung brauchbar.
Von den erwähnten Typen seien als spezielle Vertreter beispielsweise folgende öle genannt: die Polyester, die durch Umsetzung eines Gemisches aus 2 Mol Butylenglykol-i, 3 und 1 Mol Äthylenglykol mit einem Gemisch aus 1 Mol Adipinsäure und ι Mol Bernsteinsäure und durch anschließende Veresterung der verbliebenen Hydroxylgruppen mit Buttersäure erhältlich sind, ferner die Polyäther bzw. Polyesteräther, die gemäß den Beispielen 2, 3, 4 und 5 der deutschen Patentschrift 883 506 herstellbar sind.
Die Benutzung der vorgeschlagenen Schmiermittel in den erfindungsgemäß in Betracht kommenden, an sich bekannten Kälteanlagen kann in der üblichen Weise erfolgen, in der auch sonst Schmiermittel in analogen Fällen verwendet werden.
Gegenüber den bislang für den gleichen Zweck benutzten Schmiermitteln auf der Grundlage von
Mineralölen zeichnen sich die vorgeschlagenen Schmiermittel vor allem dadurch aus, daß sie sich in dem als Kältemittel dienenden Difluormonochlormethan bei den in Frage kommenden Arbeitstemperaturen im Verdampfer nicht abscheiden.
