An improved process for the esterification of carboxylic acid and alcohols into carboxylic ester is disclosed. It comprises the steps of: (a) charging the esterification reactants into a fixed bed reactor under a predetermined reaction condition; and (b) reacting the esterification reactants in ...
When no type of acid is specified, the word ester is assumed to mean a carboxylic ester, the ester of an alcohol and a carboxylic acid. The reaction, called Fischer esterification, is characterized by the combining of an alcohol and an acid (with acid catalysis) to yield an ester plus ...

Reaction pathways for the acid-catalyzed conversion of furfuryl alcohol (FAL) to ethyl levulinate (EL) in ethanol were investigated using liquid chromatography-mass spectrometry (LC-MS), 1D and 2D nuclear magnetic resonance (NMR) spectroscopy, andab initiohigh-level quantum chemical (G4MP2) calcu...
The electron pair in the C—H bond “moves” to form a carbon–carbon double bond, and the electron pair of the C—O bond is retained by the oxygen atom. The reaction with ethanol illustrates the process. In both the E1 process and the E2 dehydration reaction, the acid serves only as...

Bagasse was subjected to a liquefaction process with polyethylene glycol/glycerol using sulfuric acid as catalyst. The effects of various liquefaction conditions, such as reaction time, liquefaction temperature, catalyst content, and liquid ratio (liquefaction solvents/bagasse), on the liquefied residue (...
Esterification - Esters are formed by the reaction between an alcohol and either an organic or an inorganic acid. The esterification reaction is undertaken in a reaction column that contains a solid resin catalyst. Click here for reaction, mechanism, typ
disclosed exhibiting activity for dehydrating an alcohol, the composition comprising a source of a Group VIII transition metal, an organic salt, an acid and/or a compound consisting of a conjugate base of an acid bonded to a radical of the alcohol to be dehydrated and, optionally, a ligand....
4) [67]. During the esterification reaction of PpAAT, H165 residue directly interact with the substrate, and other amino acid residues participate in substrate recognition and spatial conformation in the reaction center. Initially, H165 is oriented to the carbonyl group of acyl-CoA, and D169 is...
