Abstract
Lubricants based on synthetic esters are provided, which are suitable for the lubrication of refrigeration machines, heat pumps and similar installations, such as air-conditioning units, which are operated with refrigerants such as HFC 134 a or similar compounds. These lubricants consist essentially of esters or ester mixtures from the reaction of predominantly straight-chain saturated monocarboxylic acids having 4 to 10 carbon atoms as the acid component and alcohols having 3 to 6 hydroxyl groups as well as one or two quaternary carbon atoms as the alcohol component.
