The influence of the heat exchange on the inhibiting effciency of some heterocyclic derivatives against copper corrosion in 3.5 percent NaCl was studied.

Abstract

The influence of the heat exchange on the inhibiting effciency of some heterocyclic derivatives against copper corrosion in 3.5 percent NaCl was studied. Tests were performed under heat exchange conditions with delltaT=60°C and the results were compared with those obtained in isothermal conditions at 35°C. The inhibiting effciency of the heterocyclic derivatives (thiadiazole, thiazoline, thiazole derivatives and 2Thioidantoine), at 10-3M and 10-4M concentration was evaluated. Some of the tested substances (in particularly 2Mercapto-5Methyl-Thiadiazole and 2Amino-5Mercapto-Thiadiazole) showed high inhibiting effciency against copper corrosion in 3.5 % NaCl solution under heat exchange conditions with deltaT=60°C.
