Abstract

The inhibitive action of 2 amino-6-chlorobenzothiazole (ACLBT) and Propargyl alcohol (PA) and their mixture on corrosion of mild steel in 15% HCI under boiling condition has been studied by weight loss method. PA gave maximum IE 99.7% at a concentration of 5000 ppm and ACLBT gave maximum IE of 62% at 4000 ppm. The combination containing 2500 ppm of PA and 1000 ppm of ACLBT gave 99.3% IE. Electrochemical polarization studies reveal that PA, ACLBT and their optimum mixture act as mixed inhibitor.
