Abstract
The novel compound provided by the invention is a higher carboxylic acid triester of adamantane triol such as adamamtane-1,3,5-triol tricaprylate not known in the prior art. The compound has a high kinematic viscosity at elevated temperatures despite the low pour point and has high thermal stability in an oxidizing atmosphere so that it is useful as an ingredient of a high-performance lubricating oil.
