摘要: Abstract The inhibition of (3ar,6ar)-3a,6a-di-p-tolyltetrahydroimidazo[4,5-d]imidazole-2,5(1 h,3h)-dithione (TTHIIDT) for carbon steel was full characterized in a 1 M hydrochloride acid environment at various inhibitor concentrations and temperatures by the gravimetric, electrochemical, surface quantum chemical analyses. obtained results confirmed that efficiency TTHIIDT over 95–97% nearly stable rise temperature concentration; mixed type effectively influenced both anodic cathodic corrosion reactions; protective hydrophobic thin layer this on is more non soluble HCl medium; adsorbed endothermically physical adsorption processes. calculations supported experimental showed depends structure inhibitor.
