Resumen
In this work, a new structured linoleic-based hydroxytetrahydrofuran (HTHF) ester lubricant with excellent properties was developed. A synthesis route through regioselective enzymatic hydration was established, combining highly selective epoxidation with an intramolecular epoxide ring-opening reaction. The results proved that the enzymatic-chemical method is an alternative strategy for the conversion of linoleic acid into bio-lubricants. LiBr was revealed as an efficient catalyst (yields of 95.8%, and selectivity of 98.5%, respectively) for the intramolecular epoxide ring-opening reaction. The tribological properties test indicated that the HTHF bio-lubricants exhibited better performance than the commercial mineral oils. Physicochemical investigation further indicated that the product has a good thermal stability, with the Tonset around 300 °C. The kinematic viscosity and viscosity index indicated that the product is suitable to be applied for lubrication. In contrast with previous findings, this HTHF-structured bio-lubricant oil exhibited a superior low pour point (−64 °C) and provided great potential to be utilized in extreme cold working environments.
