“…This outcome suggests that MTS is a potential nonedible precursor for BD creation. The molecular weight of MTSO was 871.07 g/mole, which is comparable to those established for bitter almond oil (866 g/mole) 18 and Rhazya stricta Decne seed oil (873.14 g/mole) 31 . The low PP value of MTSO suggests its high level of unsaturated fatty acids.…”

The crude oil extracted from milk thistle seeds was employed as a precursor for creating biodiesel (BD) via the cosolvent esterification–transesterification process. The high acid value of the extracted oil (11.90 mg KOH/g) encouraged its pre‐esterification in the occurrence of hexane as a cosolvent. The cosolvent esterification of oil diminished its acidity index to below 2.0 mg KOH/g using 1.5:1 hexane:methanol volume ratio, 50°C, 60‐min reaction time, 6:1 methanol:oil molar ratio, and 0.75 wt.% HCl. Alcoholysis reaction of the esterified oil with methanol and a blend of methanol:ethanol to synthesize, respectively, methylic BD and methylic/ethylic BD was accomplished in the presence of hexane as a cosolvent as well. Under the ideal reaction conditions, methylic BD yield and methylic/ethylic BD yield were 96.23% and 95.63%, respectively. The Fourier‐transform infrared (FTIR) and 1H nuclear magnetic resonance (NMR) spectra affirmed the lipid transformation from milk thistle seeds into BD. The attained samples of BD exhibited properties conforming to those specified by ASTM D6751. Also, the cosolvent methanolysis kinetic obeyed the pseudo‐first‐order with 35.94 KJ/mol activation energy and 6.32‐s frequency factor.

“…Subsequently, the yield decreases with further increase in KOH concentration. Low catalyst concentration is reported to cause low biodiesel yield due to incomplete transesterification [23] and increased acidity of triglycerides [24]. A higher KOH catalyst concentration may also cause low yield due to excess soap formation.…”

Castor oil is a unique vegetable oil with peculiar features such as extremely high viscosity and unusual miscibility with short chain alcohol. This necessitates a comprehensive exploration of all process parameters in the transesterification of castor oil, which is rarely done for other vegetable oils. In this study, the methanolysis of castor oil using alkaline catalyst (potassium hydroxide, KOH) was investigated in a batch reactor via the conventional one-variable-at-a-time protocol. The effects of process parameters including reaction time, reaction temperature, methanol-to-oil molar ratio, catalyst concentration and stirring rate on biodiesel yield were evaluated. The results indicate the significant influence of all parameters on the biodiesel yield. An optimum yield of 96% was achieved at a reaction time of 60 min, reaction temperature of 65 o C, methanol-to-oil molar ratio of 12:1, catalyst concentration of 1.5% w/w and stirring rate of 125 rpm. The fuel properties and fourier transform infra-red (FTIR) spectrum of the biodiesel obtained at optimum condition were mostly found to be in conformity with the ASTM D6751 and EN 14214 specification standards.

“…So, by alcoholysis for biodiesel production, viscosity is reduced, and this should satisfy international standards. The viscosity of date pits oil was measured to be 23.56 mm 2 .s -1 which is lower than that of most of the traditional oils currently used for biodiesel synthesis, such as soybean oil 27.45 mm 2 .s -1 [29], Yucca aloifolia oil 25.86 mm 2 .s -1 [29] and sunflower oil 29.53 mm 2 .s -1 [30].…”
