Abstract

The invention relates to a lubricating oil composition and a refrigerant composition containing a polyalkylene glycol having a terpenoid end group, such as a famesol end group.

Description

technical field [0001] This application claims the benefit of prior U.S. Provisional Patent Application No. 62 / 639,187, filed March 6, 2018, under 35 U.S.C. § 119(e), the entire contents of which are incorporated herein by reference. [0002] The present invention relates to novel polyalkylene glycols (PAGs) having terpenoid functionality, which are useful as lubricants. The present invention further relates to a composition comprising said polyalkylene glycol and a refrigerant, especially a low global warming potential (GWP) refrigerant such as a C3-C5 hydrofluoroolefin refrigerant, which can be used as a heating, ventilation And heat transfer media in refrigeration circuits of air conditioning (HVAC) systems, such as refrigerators, air conditioning units, chillers, heat pumps, etc. Background technique [0003] Fluoroolefins (“HFO” / “fluoroolefins”, such as hydrofluoroolefin (HFO) refrigerant HFO-1234yf (2,3,3,3-tetrafluoroprop-1-ene) and refrigerant HFO-1234ze (1, 3,3,...
