Reactivity of 3-Methylbenzenediazonium ions with Gallic Acid. Kinetics and Mechanism of the Reaction

Posted on 19 October, 200914 May, 2017 by antiox@uvigo.es

We investigated the kinetics and mechanism of the reaction between the 3-methylbenzenediazonium ions (3MBD), and gallic acids (=3,4,5-trihydroxybenzoic acid; GA) in aqueous buffer solution under acidic conditions by employing spectrometric, electrochemical, and chromatographic techniques and computational methods [...]

Effects of Temperature and Emulsifier Concentration on α-Tocopherol Distribution in a Stirred, Fluid, Emulsion. Thermodynamics of α-Tocopherol Transfer between the Oil and Interfacial Regions

Posted on 5 February, 200914 May, 2017 by antiox@uvigo.es

The combined linear sweep voltammetry (LSV)/pseudophase kinetic model method was used to obtain the first estimates of the free energies, enthalpy, and entropies of transfer of α-tocopherol (TOC) between the oil and interfacial regions of fluid, opaque, emulsions of n-octane [...]
