Four novel benzotriazole derivatives 1-(Chloromethyl)-1H-Benzotriazole; 1, N-(benzo[e] [1, 2, 4]triazin-4(3-H)-ylmethylbenzenamine; 2, 1-((1-H-benzo[d][1,2,3]triazol-1-yl)methyl) hydrazine; 3 and 1-((1-H-benzo[d][ 1,2,3]triazol-1-yl)methyl) phenyl hydrazine; 4 were synthesized through micro wave irradiation (MWI) method. These derivatives were characterized and tested for anticorrosive action on iron coupons in 0.5M acidic medium at different concentration. The anti-corrosive study was done using weight loss method and corrosion rate (CR) analysis. All the synthesized derivatives gave remarkable corrosion protection effect. Major outcome of the study shows corrosion inhibitor efficiency of derivatives follows order 3, 4, 2 and 1 at 100mg/L, 3, 2, 4 and 1 at 200mg/L, 3, 4, 2 and 1 at 300mg/L. Compound 1-((1-H-benzo[d][1,2,3]triazol-1-yl)methyl)hydrazine; 3 emerges as leader in all concentration in this study while 1-(Chloromethyl)-1H-Benzotriazole; 1, shows moderate impact. This study imparts an understanding for the new class of anticorrosive benzotriazole derivatives which can be of industrial use.
