H3PW12O40 (HPA), an Efficient and Reusable Catalyst for Biodiesel Production Related Reactions. Esterification of Oleic Acid and Etherification of Glycerol
(Sociedade Brasileira de Química, 2011-03)
In esterification of oleic acid with methanol at 25 °C HPA displayed the highest activity. Moreover the HPA could be reused after being transformed into its cesium salt. In the reaction of etherification of glycerol HPA ...
Niobium to alcohol mol ratio control of the concurring esterification and etherification reactions promoted by NbCl5 and Al2O3 catalysts under microwave irradiation
(ELSEVIER SCIENCE BV, 2008)
Alcohols and acids can be switched to produce ethers or esters by varying the alcohol to catalyst mol ratio, in a new etherification and esterification method using NbCl5/Al2O3 catalyst under ""solvent free"" conditions ...

Etherification of 5-hydroxymethylfurfural using a heteropolyacid supported on a silica matrix
(Elsevier, 2020-07-31)
In this work, Preyssler-type heteropolyacids and their silica-included counterparts were employed in the etherification reaction of HMF and n-BuOH. Materials were synthesized with a Preyssler acid load of 12.5% w/w using ...
Synthesis and catalytic evaluation of acidic carbons in the etherification of glycerol obtained from biodiesel production
(Elsevier Science, 2021-07)
In this paper, the catalytic behaviour of carbonaceous system (Ccs) functionalized with –SO3H groups were studied in the etherification of refined (Gly) and crude glycerol (GlyC), with benzyl alcohol (BA). This Ccs was ...
Glycerol etherification with benzyl alcohol over sulfated zirconia catalysts
(Elsevier Science, 2015-05-02)
Glycerol (GLY) etherification with benzyl alcohol (BA) was conducted with different zirconia-based heterogeneous acid catalysts, aiming to produce mono- (ME) and dibenzyl glycerol ethers (DE). Physicochemical properties ...
Acid functionalized carbons as catalyst for glycerol etherification with benzyl alcohol
(Brazilian Society of Chemical Engineering, 2020-01)
In this paper, the catalytic behaviour of two different carbonaceous systems, commercial carbon (Cc) and synthetic carbon (Cs) functionalized with concentrated sulfuric acid (–SO3H) and with reduced aryl diazonium salt ...
