Biodegradable Lubricant from <i>Idesia</i> <i>polycarpa</i> Maxim. <i>var.</i> <i>vestita</i> Diels Oil

Abstract

The chemical modified Idesia polycarpa Maxim. var. vestita Diels (IPMVVD) oil as a biodegradable lubricant was described in the paper. IPMVVD oil was modified by epoxidation and reaction of ring opening to resolve poor oxidative stability and low-temperature fluidity when vegetable oils as lubricants directly. The effects of the parameters in the process were studied, and then the product was evaluated. The results showed that the modified IPMVVD oil had higher viscosity index and superior oxidative stability comparing with unmodified oil; its mixtures with Dioctyl phthalate (DOP) offered a wide range of kinematic viscosities and lower pour point (-22°C), displayed preferable low temperature performance.

“…In generally, the yield of product will increase with more UHP initially. However, the yield was found to be decreased to 62% when the molar ratio was increased to 1:10, which was probably due to the poor stability of the epoxy ring at such molar ratio …”
