BEHAVIOR OF AMIDE-IMIDAZOLINE CORROSION INHIBITORS IN HYDROCARBON MEDIA

摘要

The Kirishinefteorgsintez Company has used an ELOU-AVT-2 equipment in comparative industrial trials on seven commercial inhibitors made by leading foreign firms (Dodigen 481, Sepacorr NT, ES 1021V, Petrotec 1200, Kemelix 1123, Cor Cliar 178) and by the Russian firm of Koltek (Hercules 30617). There is an almost complete lack of information on the composition of the commercial inhibitors, so we recorded the IR spectra of all of them. These identified the bands of amide Ⅰ (1654-1644 cm~(-1)), amide Ⅱ (1546-1514 cm~(-1)), amide Ⅲ (1301-1249 cm~(-1)), the imidazoline ring (1614-1603 cm~(-1)), unreacted amines (about 3500 cm~(-1)), salts of amines and car-boxylic acids (3000-2850, 2730-2720,2360-2340 cm~(-1)), and aromatic solvent compounds (～2000, 1225-1175, 1175-1125, 1125-1090, 1070-1000 cm~(-1)).
