Method of improving antiwear properties of high temperature hydrocarbon compositions |
摘要 |
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.
