“…This value showed that the model was trustworthy in the predicting the response and, at least 94.16 % of the variability in the data, could be de ned by the second-order polynomial model. The R2pred and R2adj values were 0.7788 and 0.9109, respectively, that show good tness of the model because these values are in reasonable agreement with together, as the values should differ by no more than 0.2 50,51 . The adequate precision is a measure of the signal to noise ratio and a quantity greater than 4 is desirable 52 .…”

Ball-Milled seashells, as a nano-biocomposite catalyst and natural source of CaCO3 in its aragonite microcrystalline form and fixed CO2, was optimized for the synthesis of isoamyl acetate by response surface methodology (RSM) with a five-level three-factor rotatable circumscribed central composite design (RCCCD). The seashells nano-biocomposite was proved to be an excellent heterogeneous catalyst for the green and environmentally-benign synthesis of isoamyl acetate from acetic acid and isoamyl alcohol under solvent-free conditions. High yield of 91% was obtained under the following optimal conditions: molar ratio of alcohol: acetic acid (1:3.7), catalyst loading (15.7 mg), the reaction temperature (98°C), and the reaction time (219 min). The outstanding advantages of this protocol are the use of a naturally occurring and easily prepared nano-biocomposite material without any modifications with hazardous reagents, lower catalyst loading and required temperature, avoiding the use of corrosive Bronsted acids as well as toxic azeotropic solvents or water adsorbents, and simplicity of the procedure.

Increasing concentrations of greenhouse gases in the atmosphere are leading to increased production and use of biofuels. The industrial development of biodiesel production and the use of biodiesel in the EU transport sector have been ongoing for almost two decades. Compared to mineral diesel production, the process of producing biodiesel is quite complex and expensive, and the search for new raw materials and advanced technologies is needed to maintain production value and expand the industrial production of biodiesel. The purpose of this article is to review the application possibilities of one of the new technologies—simultaneous extraction of oil from oily feedstock and transesterification (in situ)—and to evaluate the effectiveness of the abovementioned process under various conditions.

“…To ease the research and development of transesterification processes, a simple and reliable method for conversion determination is needed. The current methods for conversion determination of fatty methyl esters (FAME) and fatty ethyl esters (FAEE) are gas chromatography (GC), − high-performance liquid chromatography (HPLC), − and 1 H nuclear magnetic resonance ( 1 H NMR) spectroscopy. ,, Recently, biodiesel research started producing and studying biodiesel from alcohols such as 1-propanol, ,,, 2-propanol, − ,,,− 1-butanol, − ,,,,− ,, 2-butanol, ,, isobutanol, tert -butanol, , 2-methyl-1-butanol, 2,2-dimethylpropan-1-ol, 4-methylpentan-2-ol, 2-ethylhexanol, 1-pentanol, , 2-hexanol 1-hexanol, 1-octanol, 2-octanol, and 1-decanol . Biodiesel production is not limited to the mentioned alcohols and can be carried out with other alcohols (isopentanol, 1-heptanol, 1-dodecanol, and benzyl alcohol), as demonstrated in this study.…”

Correlation Method for Conversion Determination of Biodiesel Obtained from Different Alcohols by ¹H NMR Spectroscopy

et al. 2017

This work presents a correlation method that uses 1H NMR spectra for determining the conversion during transesterification of vegetable oil with 10 alcohols: methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, isobutanol, 1-pentanol, isopentanol, 1-hexanol, 1-heptanol, 1-octanol, 1-decanol, 1-dodecanol, and benzyl alcohol. Conversions ranging from 70 to 99%, depending on primary alcohol used, are obtained using organic catalyst N,N′,N″-tris(3-(dimethylamino)propyl)guanidine. Catalysts, alcohols, and intermediate products can cause signal overlapping, debilitating the use of the conventional 1H NMR method. Thus, our method uses the correlation between the triplet signal of α-carbonylmethylene and two signals of unsaturated parts of the fatty acid chain, where signal overlapping does not occur, hence, adding robustness and flexibility to the method. The method is applicable for unsaturated oils and is not affected by the amounts of residual alcohol, catalyst, or intermediate products, making it ideal for conversion determination and in situ monitoring of complex mixtures. In addition, we present a systematic analysis of the 1H NMR spectra of biodiesels produced with the mentioned alcohols.
