Application of sulfonated nanoporous carbons as acid catalysts for Fischer esterification reactions
(Elsevier, 2015-06)
Heterogeneous acid catalysts were prepared by sulfonation of nanoporous carbons (NPCs). The NPCs were produced by pyrolysis of resorcinol-formaldehyde nanoporous resins (NPRs). The NPRs were synthesized as wet gels by ...
Benzyl benzoate and dibenzyl ether from of benzoic acid and benzyl alcohol under microwave irradiation using a SiO2-SO3H catalyst
(Elsevier B.V., 2015-08-05)
A sulfonated silica gel of small surface area with large pore diameters was prepared from the sodium silicate obtained from the reaction of construction sand and sodium carbonate, and sulfated with concentrated sulfuric ...
Kinetics of the fischer esterification of palm fatty acids with isopropanol and butyl-cellosolve
(2009-01-13)
Fischer esterification of the mixture of palm fatty acids can be achieved in 80% conversion, under conditions of reactive distillation and methanesulphonic acid as catalyst. The volatility of the H2O/alcohol azeotrope ...

The molecular organization of nerve membranes. II. Glycolytic enzymes and ATP synthesis by plasma membranes of squid retinal axons
(1971)
The following glycolytic enzyme activities were demonstrated in membrane fractions isolated from squid retinal nerve: phosphoglyceric kinase, pyruvic kinase, glyceraldehyde-3-phosphate dehydrogenase, aldolase, glucose-6-phosphate ...
On the non-ideal behavior of the homogeneous esterification reaction: a kinetic model based on activity coefficients
(2015)
In this paper, we propose a kinetic model that considers the non-ideal behavior of an homogeneous acid catalyzed esterification of free fatty acids (FFA) and that has been derived regarding the well-known Fischer-Speier ...

Modelagem da difusão intrapartícula para predição da cinética da esterificação catalítica heterogênea de ácido acético e isopropanol empregando Nb2O5
(Universidade Federal de Santa MariaBrasilEngenharia QuímicaUFSMPrograma de Pós-Graduação em Engenharia QuímicaCentro de Tecnologia, 2020-09-29)
The esterification reaction is one of the most important processes of organic synthesis in liquid phase, since esters have many applications in the chemical industry. Isopropyl acetate, for example, is used as a solvent ...
Esterification of the free carboxylic group from the lutidinic acid ligand as a tool to improve the cytotoxicity of Ru(ii) complexes
(2019-02-01)
In this study, we report on the selective esterification of the carboxyl group in a coordinated ligand based on the Fischer reaction. The new [Ru(N-O)(bipy)(dppb)]PF 6 complex 1 was used as a precursor to obtain the ester ...
Banana flavor: insights into isoamyl acetate production
(Nova Science Publishers, 2011)
Isoamyl acetate is one of the most important flavor compounds used in food industries because of its characteristic banana flavor. The ester is used as a flavoring compound in many foods and drinks, such as honey, butterscotch, ...
