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

Lubricant and refrigerant compositions comprising polyalkylene glycols and uses thereof

A polyalkylene glycol having an end-group of the general formula: 

Oil miscible polyalkylene glycols and uses thereof

A working fluid for use in a compression refrigeration, air conditioning or heat pump system, is described, which has a refrigerant composed of a fluoro-olefin, and a lubricant which is a mixture of polyol ester and a polyoxyalkylene glycol, and the polyol ester is present in an amount of at least 50% by weight based on the total weight of the polyol ester and the polyoxyalkylene glycol. A lubricant, being a mixture of a polyol ester and a polyoxyalkylene glycol, is described and comprises at least 10% by weight of polyoxyalkylene glycol based on the total weight of the polyol ester and the polyoxyalkylene glycol.

Desicating synthetic refrigeration oil composition for fluoro-olefin refrigeration systems

A block copolymer is disclosed, which comprises a first block comprising polymerized units of an alkylene oxide and a second block comprising polymerized units of an alkylene oxide and a lactone, said copolymer being obtainable by polymerizing an alkylene oxide in the presence of an organic initiator to form said first block, and reacting the first block with a mixture of an alkylene oxide and a lactone. Such copolymers are found to have improved foam inhibition characteristics while maintaining their biodegradable properties.
