Heteropolyacids with Keggin structure supported on silica-alumina
(Inderscience Enterprises, 2006-08-16)
The behaviour of molybdophosphoric acid, with Keggin structure, supported on different silica-alumina mixtures, obtained by sol-gel method, was studied. Different techniques were used to synthesise the supports. In one of ...
Feasibility of the Redox Sulfur Recovery Process using Heteropoly Molybdophosphate
(Ecole Polytechnique de Montreal, 2016-06)
The feasibility of the removal of sulfide species using acid solutions of 12-molybdophosphoric acid was studied. The key factor in this purification process is the formation of a hydrogen-bonded structure between the ...
Oxidation of cyclohexanol to epsilon-caprolactone with aqueous hydrogen peroxide on H3PW12O40 and Cs2.5H0.5PW12O40
(Elsevier Science BvAmsterdamHolanda, 2008)
C-alkylation reactions catalyzed by silica-supported Keggin heteropolyacids
(Elsevier Science, 2005-06)
Aromatic alkylation reactions were studied using molybdophosphoric and tungstophosphoric acids supported on silica as catalysts. Benzene and toluene alkylation was carried out with benzyl chloride or benzyl alcohol. Also, ...
Additive synthesis by sol-gel method for its use as antimicrobial
(Elsevier, 2015-06)
The antimicrobial activity of silver nanoparticles makes this chemical element attractive for their incorporation in different materials. Additionally, heteropolyacids (HPAs) have advantages as catalysts which make them ...
Influence of the Alcohol Molecular Size in the Dehydration Reaction Catalyzed by Carbon-Supported Heteropolyacids
(Springer, 2004-03)
The catalytic performance of tungstophosphoric and molybdophosphoric acids supported on two commercial carbons, for dehydration reactions of several alcohols, was studied. The alcohol conversion depended on their molecular ...
A suitable synthesis of azlactones (4-benzylidene-2-phenyloxazolin-5-ones and 4-alkylidene-2-phenyloxazolin-5-ones) catalyzed by silica-alumina supported heteropolyacids
(Elsevier Science, 2009-01)
Eleven examples of azlactones (4-benzylidene-2-phenyloxazolin-5-ones and 4-alkylidene-2-phenyloxazolin-5-ones) were prepared via an Erlenmeyer-type synthesis from aromatic aldehydes, hippuric acid and acetic anhydride was ...
