Excess enthalpies and heat of esterification reaction in ethanol + acetic acid + ethyl acetate + water system at 313.15 K

Catalyst-free regioselective acetylation of primary hydroxy groups in partially protected and unprotected thioglycosides with acetic acid

“…Esterication of alcohols with AcOH is known to be a reversible process that occurs under thermodynamic control. [52][53][54][55][56][57][58][59] Indeed, when 6-O-acetylated product 17 was treated under the reaction conditions (80% aq AcOH, 80 C, 24 h; method B) the parent diol 16 (24%) and 4-acetate 18 (4%) were isolated from the reaction mixture in addition to the starting 6-acetate 17 (53%) (Fig. 3).…”

“…The non-catalysed (auto-catalysed) acetylation of simple alcohols is well-known. [52][53][54][55][56][57][58][59] It has been extensively studied for industrial purposes like reactive distillation, 60,61 which is used for esterication or for recovery of dilute acetic acid from wastewater. [62][63][64][65] However, only few examples of the use of this reaction for acetylation of carbohydrates are known.…”

Revisiting the Kinetics and Mechanism of Glycerol Hydrochlorination in the Presence of Homogeneous Catalysts

“…Both organic and inorganic acids can be used as catalysts for the esterification of carboxylic acids. Nowadays, efficient and intensified esterification processes are carried out in large scale with the aid of solid acid catalysts, such as cation-exchange resins, which are active, stable, and inexpensive. − …”

“…The temperature dependences of the equilibrium constants, K ′ and K ″ , were discarded because esterification reactions have relatively low reaction enthalpies. − Moreover, Gelosa et al have investigated the glycerol esterification with acetic acid in the presence of a solid acid resin as the catalyst and have shown that the equilibrium constant for this reaction under the temperature range they work was virtually constant.…”
