Abstract
Improved refrigeration lubricants useful in compression refrigeration units are esters, exhibit an excellent balance of performance characteristics, notably in the combination of good miscibility, hydrolytic stablity, wear resistance coupled with a viscosity within the range required in many commercial refrigeration units. These esters are of a hindered dihydric or trihydric alcohol such as trimethylolpentanediol and a fatty acid, where at least 80 number percent of the acyl groups are straight chain groups.
