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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Solvent Effects versus Concentration Effects in determining Rates of Base-catalysed Keto-enol Tautomerization
Iglesias, Emilia (Royal Society of Chemistry, 2005)Solvent effects of homogeneous media (such as solvent-water mixtures) in chemical reactivity may be interpreted as due to solvent polarity and/or molecular structure of solvent molecules. In microheterogeneous media (such ... -
Tautomerization of 2-acetylcyclohexanone in assemblies of cationic surfactants. Nitrosation of the enol.
Iglesias, Emilia (Royal Society of Chemistry, 2005)The kinetic study of the keto-enol interconversion of 2-acetylcyclohexanone (ACHE) has been performed in organic solvents such as dimethylsulfoxide (DMSO), 1-propanol (1-PrOH), 2-propanol (2-PrOH), methanol (MeOH), dioxane, ...
