Synergism in Mild Steel Corrosion and Scale Inhibition by a New Oxazoline in Synthetic Cooling Water

The synergistic effect caused by molybdate ions and biocide on the inhibition of mild steel corrosion and scale in simulated-cooling water system in the presence of a newly synthesized oxazoline derivative, namely, 2-phenyl-4-methyl-4((tetrazol-5-yl)methyl)oxazoline (OXA) has been studied using potentiodynamic polarization and electrochemical impedance spectroscopic method. The obtained results show that OXA inhibits the corrosion in the considered medium. The corresponding inhibition efficiency increases with inhibitor concentration and also by addition of molybdate ions. The increase of inhibiting efficiency in the presence of $${{\rm MoO}_{4}^{2-}}$$ indicates enhancement of OXA adsorption onto the metallic surface. Moreover, the effect of biocide, namely, cetyl trimethyl ammonium bromide on biofilm formation has been studied.

Characterization by epr spectroscopy of the chiral catalysts bis(oxazoline)-Cu supported in laponites

Se presenta un estudio mediante Resonancia Paramagnetica Electronica del complejo quiral Bis(oxazolina)-Cu(II) soportado en laponita (hectorita sintetica) (libre de hierro. Del mismo se concluye que el complejo se incorpora en el espacio interlamelar de la arcilla dando lugar a entidades de Cu(II) aisladas en las cuales el metal se coordina a atomos de oxigenos y nitrogenos con una simetria practicamente planocuadrada, independientemente del disolvente empleado. Ello indica, de acuerdo con los datos previos de espectroscopia de absorcion de rayos-X, que los ligandos cloruro del complejo son intercambiados en el proceso de incorporacion de forma que los oxigenos de la superficie interlaminar y externa de la arcilla actuan como contraiones.
