Trimethylolpropane fatty acid triester (TFATE) is a promising biolubricant as an environmentally friendly substitute to conventional mineral-based lubricants. However, the issues of extensive energy consumption from vacuum maintenance and feedstock saponification caused by strong alk. catalysts exist in current TFATE-based biolubricant synthesis. Here, sustainable production of biolubricant was achieved with Me oleate (MO) from non-edible oil sources as the feedstock and moderate alk. K2CO3 as the catalyst. Nitrogen gas stripping method instead of vacuum was adopted for methanol removal. The effects of agitation speed, N2 flow rate, catalyst amount, MO to trimethylolpropane (TMP) molar ratio and temperature on MO conversion and TFATE selectivity were examined The TFATE selectivity reached 95.6% under the optimized conditions. Leaching tests indicated neglectable K2CO3 dissolution in reaction products. The kinetic parameters for the three consecutive transesterification reactions were calculated In addition, the synthesized biolubricants exhibit low acid value and volatility, moderate iodine value, superior thermal stability, and good rheol. and frictional properties.
