| Summary: | Vegetable oil derived biolubricant often suffer
from low oxidative and thermal oxidative
stability, limiting their effectiveness as
lubricants. Chemical modification through the
addition of additive offers a solution to
enhance their physicochemical and tribological
properties. This study aims to analyse the
impact of incorporating Methyl Laurate (ML) as
an additive to Trimethylolpropane (TMP)
Trioleate biolubricant and determine the
optimal ML concentration. Three types of ML
provided by Wilmar Oleochemicals & Biofuels
were tested, with ML concentrations ranging
up to 15 wt% in TMP trioleate. The double
bond content, evaluated through the iodine
value (IV), influenced the oxidative stability of
the biolubricant. Wettability was assessed
using Image J software following ASTM D733,
and viscosity-temperature relations were
analysed to determine the viscosity index (VI)
according to ASTM D445. Results showed that
100% ME1299 ML type exhibited the lowest IV,
better wettability, and higher VI. Therefore,
adding 15 wt% of 100% ME1299 ML to TMP
trioleate yielded the most desirable
combination, resulting in improved viscositytemperature relations compared to the base
oil. |
