The lubricating characteristics of high temperature fluids used in Rankine Cycle and heat pump systems has been enhanced by incorporating therein heterocyclic arenes containing 8 to about 18 ring carbon atoms and an average of 1 to 2 ring nitrogen or S atoms per arene, and optionally 1 to 2 ring O atoms with substituents such as alkyl, amino, keto oxygen or hydroxyl groups.

Method of improving antiwear properties of high temperature hydrocarbon

Synthetic polyol ester fluids useful as lubricants or hydraulic fluids have been prepared by the esterification of ethylene-methyl formate telomerization products with polyols containing from two to about six hydroxyl groups.
