Benzyne-Mediated Esterification Reaction
Organic Letters, 2021A benzyne-mediated esterification of carboxylic acids and alcohols under mild conditions has been realized, which is made possible via a selective nucleophilic addition of carboxylic acid to benzyne in the presence of alcohol. After a subsequent transesterification with alcohol, the corresponding esters can be produced efficiently.

Ynamide-Mediated Intermolecular Esterification
The Journal of Organic Chemistry, 2020An ynamide-mediated one-pot, two-step intermolecular esterification via the condensation of carboxylic acids with nucleophilic hydroxyl species was reported. A broad substrate scope with respect to carboxylic acids, alcohols, and phenols was observed. The α-acyloxyenamide intermediates formed by the addition of carboxylic acids to ynamides proved to be

Enzyme catalyzed esterification
Biotechnology Advances, 1997Enzyme catalyzed esterification reactions have found many applications, ranging from the modification of vegetable oils for human consumption to the production of optically pure chemicals. To displace the equilibrium in favor of synthesis, rather than hydrolysis, these reactions are performed in non-aqueous or microaqueous media.

Esterification and Selective Esterification in the Presence of TiCl4
Chemical Research in Chinese Universities, 2007Abstract A series of carboxylic acids was esterified to the corresponding esters with TiCl4 as catalyst at room temperature, in high yields. This catalyst was highly effective for the selective esterification of primary alcohols with carboxylic acids, in the presence of secondary alcohols, and for the selective esterification of saturated acid with ...

Thermodynamics of enzyme-catalyzed esterifications: I. Succinic acid esterification with ethanol
Applied Microbiology and Biotechnology, 2017Succinic acid (SA) was esterified with ethanol using Candida antarctica lipase B immobilized on acrylic resin at 40 and 50 °C. Enzyme activity in the reaction medium was assured prior to reaction experiments. Reaction-equilibrium experiments were performed for varying initial molalities of SA and water in the reaction mixtures. This allowed calculating

Esterification process development
Chemical Engineering Science, 1968Abstract This paper presents the development of several alternate processes for the manufacture of isopropyl acetate by the esterification of isopropanol and acetic acid. The isopropyl acetate ester was chosen for this study because it is representative of esters which form ternary azeotropes with water and the component alcohol, and which boil at a ...

Enzymatic gallic acid esterification
Biotechnology and Bioengineering, 1985AbstractGallic acid esters of n‐propyl and amyl alcohols have been produced by enzymatic synthesis in organic solvents using immobilized tannase. Studies indicate that maximum esterification of gallic acid occurs with amyl alcohol. The enzyme shows broad alcohol specificity.
