• Application of Enzymatic Extracts from a CALB Standard Strain as Biocatalyst within the Context of Conventional Biodiesel Production Optimization 

  Luna, Diego; Bautista, Felipa M.; Luna, Carlos; Estevez, Rafael; Calero, Juan; Posadillo, Alejandro; Romero, Antonio A.; Sancho, Enrique D. (MDPI, 2017)

  The application of biocatalysts in the transesterification process of triglycerides (TG) allows integrating the glycerol in the form of monoglyceride (MG), sharply increasing the yield and the environmental sustainability ...

• Coumarin Derivatives Solvent-Free Synthesis under Microwave Irradiation over Heterogeneous Solid Catalysts 

  Bouasla, Souad; Amaro-Gahete, J.; Esquivel, Dolores; López, M. Isabel; Jiménez-Sanchidrián, César; Teguiche, Mabrouk; Romero-Salguero, F.J. (MDPI, 2017)

  A suitable methodology of synthesis of coumarin derivatives by Pechmann reaction over heterogeneous solid acid catalysts in a free solvent media under microwave irradiation is described. Resorcinol, phenol and ethyl ...

• Sulfonic Acid Functionalization of Different Zeolites and Their Use as Catalysts in the Microwave-Assisted Etherification of Glycerol with tert-Butyl Alcohol 

  Estevez, Rafael; Iglesias, Ivan; Luna, Diego; Bautista, Felipa M. (MDPI, 2017)

  The etherification of glycerol with tert-butyl alcohol in the liquid phase, over different sulfonic acid functionalized zeolites, has been studied. The reaction was carried out using microwaves as a way of heating, ...

• Microemulsion and Sol-Gel Synthesized ZrO2-MgO Catalysts for the Liquid-Phase Dehydration of Xylose to Furfural 

  Parejas Barranco, Almudena; Montes, Vicente; Hidalgo-Carrillo, J.; Sánchez López, Elena; Marinas, Alberto; Urbano Navarro, Francisco José (MDPI, 2017)

  Two series of catalysts were prepared by sol-gel and microemulsion synthetic procedure (SG and ME, respectively). Each series includes both pure Mg and Zr solids as well as Mg-Zr mixed solids with 25%, 50% and 75% nominal ...

• Sol-Gel Immobilisation of Lipases: Towards Active and Stable Biocatalysts for the Esterification of Valeric Acid 

  Cebrián-García, Soledad; Balu, Alina M.; García, Araceli; Luque, Rafael (MDPI, 2018)

  Alkyl esters are high added value products useful in a wide range of industrial sectors. A methodology based on a simple sol-gel approach (biosilicification) is herein proposed to encapsulate enzymes in order to design ...
