Thermodynamic Assessment of Chemical Equilibrium for the Synthesis of Solketal in the Liquid Phase
(Wiley VCH Verlag, 2021-05-05)
The synthesis of solketal is one of the innovative routes of glycerol valorization to value-added products, and the simulation of the process requires the knowledge of thermodynamic properties that are not still available ...
Acidic V-MCM-41 catalysts for the liquid-phase ketalization of glycerol with acetone
(Elsevier Science, 2019-01)
SiMCM-41 and V-MCM-41 were hydrothermally synthesized with different quantities of vanadium, characterized by small angle X-ray scattering, nitrogen physisorption, and the insertion of vanadium was assessed by temperatur ...
Solketal synthesis from ketalization of glycerol with acetone: A kinetic study over a sulfated zirconia catalyst
(Elsevier Science, 2021-07-15)
In this work, a series of acid catalysts were synthetized from a commercial zirconium oxide sulfated with a 0.5 M H2SO4 solution by wet impregnation. The characterization results show a correlation between the calcination ...

The effect of mesoporosity in the reaction of vinyl acetate and isoamyl alcohol catalyzed by H-ZSM-5 zeolites based on natural Perlite
(Elsevier Science, 2020-07-25)
Diverse ZSM-5 zeolites having a dual porosity and different acidic properties have been prepared using natural Perlite as source of SiO2 and Al2O3. Two traditional methodologies were selected to generate hierarchical ...
Isoamyl acetate preparation from reaction of vinyl acetate and Isoamyl alcohol catalyzed by H-ZSM-5 zeolite: a kinetic study
(Elsevier Science, 2018-06)
Microporous H-ZSM-5 zeolite having good crystallinity and with the presence of Brønsted acid sites exclusively, was prepared by hydrothermal treatment of Expanded Perlite. The as-prepared H-ZSM-5 was used as heterogeneous ...
Structural Diversity in Galactans From Red Seaweeds and Its Influence on Rheological Properties
(Frontiers Media, 2020-09)
Galactans are important components of many plant cell walls. Besides, they are the major polysaccharides in extracellular matrixes from different seaweeds, and other marine organisms, which have an acidic character due to ...
