Fourth generation synthesis of solketal by glycerol acetalization with acetone: A solar-light photocatalytic approach
Hidalgo-Carrillo, J.; Estévez, R.; López Tenllado, Francisco Javier; Bautista, Felipa M.; Urbano, Francisco José; Marinas, Alberto (Elsevier, 2021)Background: Biomass is the only renewable alternative to fossil fuels to produce chemicals. In this sense, glycerol is an important biomass-derived platform chemical obtained as a by-product during biodiesel generation. ... -
Optimization by response surface methodology of the reaction conditions in 1,3-selective transesterification of sunflower oil, by using CaO as heterogeneous catalyst
Calero, Juan; Luna, Diego; Luna, Carlos; Bautista, Felipa M.; Romero, Antonio A.; Posadillo, Alejandro; Estévez, R. (Elsevier, 2020)In this work, the experimental conditions for the transesterification reaction of sunflower oil, over commercial calcium oxide (CaO) as heterogeneous catalysts, have been optimized employing a multi-factorial design based ... -
Sulfonated carbons from olive stones as catalysts in the microwave-assisted etherification of glycerol with tert-butyl alcohol
Estévez, R.; Aguado-Deblas, Laura; Montes, Vicente; Caballero, Álvaro; Bautista, Felipa M. (Elsevier, 2020)Sulfonated carbons have been prepared from an important waste in Andalusia, the olive stones. The sulfonic acid groups incorporation has been made by sulfuric acid treatment and different conditions have been tested, i.e., ... -
Sulfonated organosilica-aluminum phosphates as useful catalysts for acid-catalyzed reactions: Insights into the effect of synthesis parameters on the final catalyst
Aguado-Deblas, Laura; Estévez, R.; López Tenllado, Francisco Javier; Luna, Diego; Bautista, Felipa M. (Elsevier, 2022)The synthesis, by a sol-gel method, of organosilica-aluminum phosphates, (X)-AlPO(Y)-(Z), using three different silica precursors (X) 2-(4-chlorosulfonylphenyl)ethyltrimethoxysilane (C), 3-(mercaptopropyl)trimethoxysilane ...
