Briefly, [beta]-CD (0.5 g) was deprotonated by dissolving sodium methoxide (14.4 mmol) in dried methanol.
The transesterification reaction of triglycerides from 500 g of refined commercial soybean oil free of synthetic antioxidants was carried out with absolute methanol, analytical grade, and sodium methoxide as a catalyst, at a concentration of 0.8 g 50 m[L.sup.-1] of methyl alcohol, under reflux, heating at 60[degrees]C and stirred slow for 2 hours in a specific flask for synthesis according Angilelli, Ferreira, Silva, Chendynski, and Borsato (2017).
Methanol, used in conjunction with chloroform for the extraction procedure and to make the sodium methoxide solution, was supplied by Sigma-Aldrich and of Chromasolv quality (France).
Then, 2 ml 0.5 M sodium methoxide in methanol and 1 ml heptane containing 1 mg/ml C13:0, as an internal standard, were added and then heated for 15 min at 50[degrees]C.
The biodiesel was obtained by the transesterification of the extracted crude oils, using the potassium methoxide as a catalyst.
Extracted lipids were methylated and transesterified using sodium methoxide at pH 3, according to the method of Park and Goins [16].
The sodium methoxide solution has been prepared by mixing the different methanol to oil ratio by volume (7:1, 8:1, 9:1, and 10: 1) with NaOH and stirred at 250 rpm using a magnetic stirrer and heated the contents continuously for 90 min [22].
The mixture was then heated by constant stirring for 1 hour on hot plate with magnetic stirrer to obtain sodium methoxide. 1 liter of each preheated WFOs was mixed with sodium methoxide solution and heated at 50 AdegC under continuous stirring at a fixed speed (250 rpm) for 90 minutes.
