Synthesis, Properties, and Techno-economic Analysis of Highly Stable Biotransformer Oil Derived from Transesterification of Palm Oil Methyl Esters and Ditrimethylolpropane
Currently, biotransformer oil (BTO) is in high demand due to the increasing level of electrical power consumption and environmental policy. Hence, this research aimed to prepare a highly stable BTO via basic transesterification of palm oil methyl ester (POME) and ditrimethylolpropane (Di-TMP) catalyzed by sodium methoxide (NaOCH<sub>3</sub>). Under the optimal conditions (POME/Di-TMP molar ratio = 5.0/1.0, NaOCH<sub>3</sub> loading = 8 mol % based on the Di-TMP content under 3.5 mbar, and 300 rpm at 160 °C for 2 h), the POME conversion level and POME-Di-TMPTTE selectivity reached 90.3% and 96.6%, respectively. The obtained BTO with a high POME-Di-TMPTTE portion exhibited greater oxidation stability with a higher flash point and breakdown voltage in accordance with the IEC 62770 specification. A techno-economic analysis revealed the possibility of POME-Di-TMPTTE as a commercial BTO for its competitive cost and profit based on the current commercial price of BTO.
