Abstract
Dissolution rates of aluminium in hydrochloric acid solution containin g substituted N-(o-hydroxybenzylidene) have been examined. Using three different techniques; weight loss, thermometric and gasometric. The i nhibition character of the compounds depends on the concentration of t he inhibitor as well as its chemical constitution. The efficiencies of the additives decrease with rise in temperature confirming the idea t hat the inhibition occurs through physical adsorption.
