“…The products of this process has great industrial applications, such as triacetin has been used for pharmaceutical and cosmetics industry, while monoacetin and diacetin have been applied in cryogenic industry and used as raw material for biodegradable polyesters manufacture (Galan et al, 2009;Reddy et al, 2010;Rahmat et al, 2010). Besides, triacetin is a promising alternative chemical to be transformed into fuel additive (Rao & Rao, 2011;Ferreira et al, 2009;Hou et al, 1998).…”

Glycerol as byproduct of biodiesel production is a very promising low-cost feedstock for producing a wide variety of special and fine chemicals. This great amount of glycerol needs to be converted into higher valuable products. One of glycerol's derivatives potential is triacetin, a good bio-additive as anti-knocking agent. In previous work triacetin synthesis from glycerol and acetic acid using sulfuric acid catalyst has been conducted in batch and continuous process. In this work, triacetin was synthesized using reactive distillation. The continuous process has 98.50% of glycerol conversion with 8.98% of triacetin selectivity.

“…As a matter of fact the partially acetylated intermediates (MAG and DAG) tend to accumulate to some extent. This is not surprising because, as observed in the case of the esterification of glycerol with acetic acid, the reaction between the third acyl group and the di-acetyl glycerine has an equilibrium constant significantly lower than the first acylation step [7,17].…”

a b s t r a c tThe simultaneous synthesis of butyric acid methyl ester, the shortest component of the FAME (fatty acid methyl esters) family, and glycerol triacetate (TAG) from glycerol tributyrate (tributyrin) and methyl acetate was studied as a function of several reaction parameters, such as type of catalyst, temperature and products distribution. The reaction is an interesterification, a multistep consecutive ester interchange catalyzed by either acid or base catalyst. Under optimized conditions, a complete tributyrin conversion and an almost quantitative butyric acid methyl ester accumulation were achieved. The other reaction product, TAG, formed by the complete acetylation of the glycerol moiety, reached almost 70% yield, whereas the mono-and di-acetylated intermediates accumulated in the order of 5-8% and 24-27%, respectively. Similar final conversions and products yields were obtained with either acid or base homogeneous catalysts, suggesting that the final products mixture did not depend on the type of catalysis but might be limited by equilibrium conditions. In spite of similar final yields, base catalysis needed shorter reaction times (minutes instead of hours) and lower temperature (60 • C instead of 130 • C) with respect to the best acid catalyst. On the other hand, unlike heterogeneous basic catalysts, which showed low activity, a heterogeneous acid catalyst almost as active as the homogenous counterpart was found.

“…Triacetin, triacetate ester of glycerol, is a colorless fuel oil, being poorly soluble in water 43,44 . Triacetin can be obtained by means of methyl acetate transesterification or glycerol esterification with acetic acid, also yielding in di-acetin and mono-acetin (intermediate products).…”

Oxygenated Glycerol Derivatives as an Alternative Source of Energy: A Review

et al. 2017

View full text Add to dashboard Cite

Due to the excessive production of crude glycerol by the Brazilian biodiesel industries, the commercial interest for glycerol derivatives has widely increased. Therefore, several methodologies have been proposed for such purpose, combining the reuse of this abundant raw material with new applications. In such context, this review summarizes a number of works focused on oxygenated glycerol derivatives production, regarding the reactions mechanisms (etherification, acetalization, esterification, and fermentation) and the physicochemical chemical properties and application. Thus, this work aims to contribute to future studies in chemical modification of crude glycerol; hence most of the scientific publications have discussed additives yielded from pure glycerol.
