Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The effect of 5-Chloroisatin derivatives as a corrosion inhibitors on mild steel in acid medium was studied through weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. Scanning electron microscopy (SEM) was employed to analyze the surface topography of the uninhibited and inhibited mild steel. The inhibition efficiency of the inhibiting compound increases with increase in inhibitor concentration at 303K, resulting in significant decrease in corrosion rate of the mild steel. Thermodynamic adsorption and activation parameters were calculated for the corrosion inhibition process adsorption of 5-Chloroisatin derivatives on the steel obeyed the Langmuir adsorption model. …

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - We prepared new 5-chloroisatin derivatives via alkylation reactions under liquid-solid phase transfer catalysis conditions using various alkylating agents. In all cases, we were able to isolate a single type of N-alkyl compound in good yields. Subsequently, we developed the synthesis of five-membered heterocycles through 1,3-dipolar cycloaddition reactions on the dipolarophilic groups of 5-chloroisatin (the carbonyl group at position 3 and the allyl chain at position 1).…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Se estudió el efecto de los derivados de la 5-cloroisatina como inhibidores de la corrosión en el acero dulce en medio ácido mediante técnicas de pérdida de peso, polarización potenciodinámica y espectroscopia de impedancia electroquímica (EIS). Se empleó la microscopía electrónica de barrido (SEM) para analizar la topografía superficial del acero dulce sin inhibición y con inhibición. La eficacia inhibidora del compuesto inhibidor aumenta al incrementarse la concentración del inhibidor a 303 K, lo que da lugar a una disminución significativa de la velocidad de corrosión del acero dulce. Se calcularon los parámetros termodinámicos de adsorción y activación para el proceso de inhibición de la corrosión; la adsorción de los derivados de la 5-cloroisatina sobre el acero se ajustó al modelo de adsorción de Langmuir.…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Dans ce travail, nous avons montré que le tensioactif (TA) phosphonate polymérisable (MP11) a pu être obtenu par une voie de synthèse originale. Ce dernier a été parfaitement caractérisé par RMN 1H et 31P. Sa concentration micellaire critique a été déterminée dans l'eau par conductimétrie et évaluée à 2,4.10-2 M. Après avoir rappelé quelques généralités sur la polymérisation en émulsion. Nous avons pu mettre en évidence les propriétés émulsifiantes de notre TA MP11. Après l'étude de sa vitesse de polymérisation nous l'avons copolymérisé avec du styrène en émulsion. A l'aide de la RMN 31P et microscopie MEB, nous avons montré l'incorporation effective du MP11 respectivement dans la structure du polymère et sur la surface des particules. Enfin, nous avons montré que l'utilisation du MP11 à 2 % en masse permet l'obtention d'un latex avec un diamètre de particules de l'ordre de 53 nm. Valeur tout à fait comparable à celles obtenues dans des cas similaires. …
