    • Micellar effects on aromatic esters hydrolysis 

      Brandariz, Isabel; Iglesias, Emilia (Elsevier, 2014-07)
      The alkaline hydrolysis of two aromatic esters, 2-naphthyl acetate (2NA) and phenyl acetate (PhA) has been tackled in this work. The reaction has been followed in water and in the presence of cationic surfactants with ...

    • A further study of acetylacetone nitrosation 

      Iglesias, Emilia; Brandariz, Isabel (Royal Society of Chemistry, 2013-02)
      The nitrosation of acetylacetone (AcAc) has been revised in an aqueous acid medium of perchloric acid and buffers of mono-, di-, or tri-chloroacetic acid. The results show that in the presence of buffers, under conditions ...

    • Potentiometric characterisation of cyclodextrin inclusion complexes of local anaesthetics 

      Brandariz, Isabel; Iglesias, Emilia (Taylor and Francis Ltd., 2011-09)
      The complexation of several local anaesthetics by β and γ-cyclodextrins was studied by potentiometry with glass electrode. Tetracaine and dibucaine complexation constants were determined at 25°C in the presence of 0.1 M ...

    • Iron(III) complexation by Vanchrobactin, a siderophore of the bacterial fish pathogen Vibrio anguillarum 

      Iglesias, Emilia; Brandariz, Isabel; Jiménez, Carlos; Soengas, Raquel G. (Royal Society of Chemistry, 2011-05)
      The bacterial fish pathogen Vibrio anguillarum serotype O2 strain RV22 produces the mono catecholate siderophore Vanchrobactin (Vb) under conditions of iron deficiency. Vb contains two potential bidentate coordination ...

    • Fluorescence study of tetracaine–cyclodextrin inclusion complexes 

      Iglesias García, Iván.; Brandariz, Isabel; Iglesias, Emilia (Taylor and Francis Ltd., 2010-04)
      The steady-state fluorescence emission from the local anaesthetic tetracaine (TCA) in water-solvent mixtures and in the presence of α-, β- and γ-cyclodextrin (CD) was investigated at various pH values. Emission was observed ...
