Abstract EN
For environmental reasons, a new class of environmentally acceptable and renewable biolubricant based on vegetable oils is available.
In this study, oxirane ring opening reaction of monoepoxide linoleic acid (MEOA) was done by nucleophilic addition of oleic acid (OA) with using p-toluene sulfonic acid (PTSA) as a catalyst for synthesis of 9(12)-hydroxy-10(13)-oleoxy-12(9)-octadecanoic acid (HYOOA) and the physicochemical properties of the resulted HYOOA are reported to be used as biolubricant base oils.
Optimum conditions of the experiment using D-optimal design to obtain high yield% of HYOOA and lowest OOC% were predicted at OA/MEOA ratio of 0.30 : 1 (w/w), PTSA/MEOA ratio of 0.50 : 1 (w/w), reaction temperature at 110∘C, and reaction time at 4.5 h.
The results showed that an increase in the chain length of the midchain ester resulted in the decrease of pour point (PP) −51∘C, increase of viscosity index (VI) up to 153, and improvement in oxidative stability (OT) to 180.94∘C.
