Determination of Critical Micelle Concentration of Some Surfactants by Three Techniques
The laboratory experiments described in this work present the CMC-determination of some surfactants by following three different methods, which require the use of the very common techniques inExpand
Effects of Additives on the Internal Dynamics and Properties of Water/AOT/Isooctane Microemulsions
The influence of several additives, frequently present in reactions carried out in microemulsions, upon the properties of the system water/AOT/isooctane has been investigated. Electrolytes (salts,Expand
Quantitation of nifedipine in human plasma by on-line solid-phase extraction and high-performance liquid chromatography.
An analytical methodology for nifedipine quantitation in plasma by on-line solid-phase extraction (SPE) and high-performance liquid chromatography (HPLC) is described. The SPE cartridges contain C2Expand
Iron(III) complexation by Vanchrobactin, a siderophore of the bacterial fish pathogen Vibrio anguillarum.
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 potentialExpand
Kinetics of acid and nucleophile catalysis of the diazotization of 1-naphthylamine
The diazotization of 1-naphthylamine has been studied at acidities ranging from 10−2 to 1.5 M. At low acidities nitrosation takes place via the unprotonated form of the amine, and theExpand
Enolization of Benzoylacetone in Aqueous Surfactant Solutions: A Novel Method for Determining Enolization Constants
The keto−enol tautomerism of benzoylacetone (1-phenyl-1,3-butadione) in aqueous acidic solution at 25 °C was investigated by studying the influence of anionic, cationic, and nonionic surfactants inExpand

The keto-enol tautomerism of 2-acetylcyclohexanone (ACHE) was studied in water under different experimental conditions. By contrast with other previously studied beta-diketones, the keto-enolExpand
Kinetics and mechanism of the nitrosation of N-acetyltryptophan and of the denitrosation of N-acetyl-N1-nitrosotryptophan
Both the formation and the denitrosation of N-acetyl-N1-nitrosotryptophan have been studied kinetically in aqueous solution at 25 °C at acidities between 1 M-HClO4 and pH 4. A value of 850 l mol–1Expand
CYCLODEXTRINS AS ENZYME MODELS IN NITROSATION AND IN ACID: BASE-CATALYZED REACTIONS OF ALKYL NITRITES
The widely studied cyclodextrin-mediated reactions of esters but not those of alkyl nitrites, together with the marked differences between the chemistry of esters and alkyl nitrites, prompted us toExpand
