    • [BMIM][PF6] Promotes the synthesis of halohydrin esters from diols using potassium halides 

      Oromí Farrús, Mireia; Eras i Joli, Jordi; Villorbina Noguera, Gemma; Torres i Grifo, Mercè; Llopis-Mestre, Verónica; Welton, Tom; Canela i Garayoa, Ramon (Japan Society for Analytical Chemistry, 2008)
      Haloesterification of diverse diols with various carboxylic acids was achieved using potassium halides (KX) as the only halide source in ionic liquids. The best yield was obtained in [BMIM][PF6] when 1,2-octanediol, palmitic ...
    • Combining AlCl3·6H2O and an ionic liquid to prepare chlorohydrin esters from glycerol 

      Villorbina Noguera, Gemma; Tomàs, Albert; Escribà i Gelonch, Marc; Oromí Farrús, Mireia; Eras i Joli, Jordi; Balcells Fluvià, Mercè; Canela i Garayoa, Ramon (Elsevier, 2009)
      We describe here the first example in which glycerol has been transformed into chlorohydrin esters using an ionic liquid and hydrated aluminium chloride. The method avoids using Crown-18 ether, which was needed to obtain ...
    • Combining regio- and enantioselectivity of lipases for the preparation of (R)-4-chloro-2-butanol 

      Méndez, Jonh Jairo; Oromí Farrús, Mireia; Cervero, Maria; Balcells Fluvià, Mercè; Torres i Grifo, Mercè; Canela i Garayoa, Ramon (Wiley, 2007)
      Preparation of 98% ee (R)-4-chloro-2-butanol was carried out by the enzymatic hydrolysis of chlorohydrin esters, using fungal resting cells and commercial enzymes. Hydrolyzes were carried out using lipases from Candida ...
    • Determination of the iodine value of biodiesel using 1H NMR with 1,4-dioxane as an internal standard 

      Oromí Farrús, Mireia; Villorbina Noguera, Gemma; Eras i Joli, Jordi; Gatius Cortiella, Ferran; Torres i Grifo, Mercè; Canela i Garayoa, Ramon (Elsevier, 2010)
      Iodine values (IVs) of some biodiesel samples were analyzed using both 1H NMR and a standard iodometric method. 1H NMR was carried out with and without 1,4-dioxane as an internal standard (IS). The results obtained using ...
    • Preparation of (S)-1-halo-2-octanols using ionic liquids and biocatalysts 

      Oromí Farrús, Mireia; Eras i Joli, Jordi; Sala i Martí, Núria; Torres i Grifo, Mercè; Canela i Garayoa, Ramon (Molecular Diversity Preservation International, 2009)
      Preparation of (S)-1-chloro-2-octanol and (S)-1-bromo-2-octanol was carried out by the enzymatic hydrolysis of halohydrin palmitates using biocatalysts. Halohydrin palmitates were prepared by various methods from palmitic ...
