Transesterification and Epoxidation of Oil Extracts from Selected Plants for Use as Bio-transformer Oil

Characterization, kinetics and thermodynamics of epoxidation-esterification of Irvingia gabonensis kernel oil methyl ester

“…The difference in density of IGKO in this study, compared to other IGKO reported in the literature, could be associated with diverse morphologies of the seeds/kernels, and methods of extracting the oils ( Ikya et al., 2013 ). However, the density of IGKO (900 ) in this study was observed to be higher, compared to those of Jatropha (720 ), Moringa (520 ), Castor (740 ) and cotton (850 ) oils ( Aliyu and Tijjani, 2017 ). Also, the difference in density of IGKO, compared to other vegetable oil seeds/nuts could be associated with diverse morphologies of the seeds, as well as the method of extracting the oils ( Agu et al., 2019 ).…”

“…This value was also found to be greater than the 2 3 and -1.15 , reported for Moringa seed, Terminalia catappa L. kernel and castor seed oils, by Aliyu and Tijjani (2017) , Agu et al. (2019) and Aliyu and Tijjani (2017) , respectively. Pour point of MIGKO e was less than -8 , 2.40 , 4 °C and 8 °C values, reported by Agu et al.…”

“…As earlier inferred, the differences in viscosities of IGKO in this study, and other IGKO reported in literature was likened to the extraction method used, in addition to the differences in their respective species ( Agu et al., 2019 ). IGKO viscosity (19.37 ) in this work was found to be higher than the viscosity of other seeds/nuts oils like, Jatropha (16.50 ), Moringa (11.80 ), and Castor (18.10 ) ( Aliyu and Tijjani, 2017 ). However, the viscosity of IGKO in this work was found to be lower, compared to those of Sunflower oil (34.5 ) ( Rouabeh et al., 2019 ), Coconut oil (29 ) ( Aimi and Hussin, 2014 ), Cotton oil (29.40 ) ( Aliyu and Tijjani, 2017 ), Palm oil (29.2 ) ( Aimi and Hussin, 2014 ), Terminalia catappa L. kernel oil (20.29 ) ( Agu et al., 2019 ) and Olive oil (110.3 ) ( Rouabeh et al., 2019 ).…”

The differences in viscosity of these other seeds/nuts reported in the literature and that of IGKO in this study, was attributed to the difference in the morphologies of the seeds/nuts, in addition to the extraction method chosen for extraction purposes ( Agu et al., 2019 ).…”

“…Furthermore, the flash point of IGKO was found to be higher than those of coconut oil (225 ), Terminalia catappa L. kernel oil (260 ) and Jetropha oil (146 ), as reported by Aimi and Hussin (2014) , Agu et al. (2019) and Aliyu and Tijjani et al. (2017) , respectively.…”
