In the present study, batch scale biodiesel production was carried out using castor oil by alkali-catalyzed transesterification process was reported. Initially, the transesterification parameters like reaction time, catalyst concentration, reaction temperature and oil: methanol molar ratio on biodiesel production was optimized by conventional method followed by statistical based central composite design method. According to the optimized exptl. results, the maximum of 94.9% FAME yield was obtained at 60°C with 1.25% (w/v) KOH catalyst and 1:12 oil: methanol molar ratio for 60 min of reaction, which was in agreement with the predicted yield (93.7%). The purification of crude biodiesel was performed by simple evaporation and silica gel adsorption. The quality of fatty acid Me ester was examined by Fourier Transform IR spectroscopy (FT-IR), Thin layer chromatog. (TLC) and Gas Chromatog.-Mass Spectrometry (GC-MS). The anal. results showed that significant quantity of Me ester groups like ricinoleic, linolenic, palmitic acid and oleic acid were present in the biodiesel. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8COA of Formula: C20H40O2).
Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.COA of Formula: C20H40O2
