Oxygenated biofuels: Synthesis of fatty acid solketal esters with a mixture of sulfonated silica and (Bu4N)(BF4) catalyst
(2019-02-01)
Amorphous SiO2-SO3H [1] with a small surface area and 1.32-mmol H+/g was used for the one-step preparation of solketal from glycerol and acetone; a 20%-w/w catalyst mixture (10% [1] and 10% (Bu4N)(BF4) was found to be very ...
Ketalization of glycerol to solketal in supercritical acetone
(Elsevier Science, 2011-08)
In the last few years, the increasing production of biodiesel has led to an overproduction of glycerol, the main byproduct of this industry. This paper reports on the ketalization of glycerol in supercritical acetone to ...
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 ...

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 ...
Studies on dispersion and reactivity of vanadium oxides deposited on lamellar ferrierite zeolites for condensation of glycerol into bulky products
(2018-10-01)
The acetalization of acetone with glycerol was investigated using vanadium-impregnated catalysts. The siliceous supports FER, a purely microporous material, and ITQ-6, a micro/mesoporous material, were obtained from a ...
