Tautomerization of 2-acetylcyclohexanone in assemblies of cationic surfactants. Nitrosation of the enol.
(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, ...
Solvent Effects versus Concentration Effects in determining Rates of Base-catalysed Keto-enol Tautomerization
(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 ...
Equilibrium constants of triethanolamine in major seawater salts
(Elsevier, 2006-12)
Acid–base equilibrium constants of triethanolamine (TEA) have been determined by potentiometric titrations with a glass electrode, at 25 °C. Ionic strength was kept constant with only one electrolyte (using one of these ...
Iron(III) complexation by Vanchrobactin, a siderophore of the bacterial fish pathogen Vibrio anguillarum
(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
(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 ...
Effect of ionic strength on the formal potential of the glass electrode in various saline media
(Elsevier, 1998-08)
We examined the variation with ionic strength (I, adjusted with KCl, KNO3, KBr, NaCl or NaClO4) of the formal potential (Econst) for glass electrodes exhibiting a Nernstian response (i.e. Ecell=Econst−s log [H+]). For this ...
Salting coefficient of triethanolamine in major seawater salts
(Elsevier, 2006-01)
Activity coefficient of triethanolamine (TEA) in major seawater salts (NaCl, KCl, CaCl2 and MgCl2) has been determinated using the distribution method. It increases slowly in KCl, remains almost constant in NaCl and decreases ...
The salting coefficient and size of alkylamines in saline media at different temperatures: estimation from Pitzer equations and the mean spherical approximation
(Elsevier, 2001-04)
The renewed theoretical interest in the proton transfer associated to the amino group together with the scarcity of acid-base studies of amines in moderate to concentrated saline media focussed our attention on the study ...
Micellar effects on aromatic esters hydrolysis
(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
(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 ...
