Abstract: 

The use of temporary corrosion protective is one of the best ways against the corrosion of steels that can be easily removed from the metal surface after treatment. In this research, N,N'-(3,3',4,4'-Benzophenonetetracarboxylic)-3,3',4,4'-diimido-bis-(aminonaphthalene-4-sulfonicacid) (BTDIAS) was synthesized as a new organic corrosion inhibitor. This sulfonated compound added to the base oil with a concentration of (2-100) ppm. The efficiency of sulfonated compound as organic corrosion inhibitor is evaluated by weight loss method and surface photography. The solutions of sulfonated compound (BTDIAS) (2-100) ppm in base oil were used on the low carbon steel surfaces, as a temporary corrosion protector. The samples were tested in a humidity chamber based on standard method (ASTM D-2247). The samples containing (5-30) ppm sulfonated compound showed the best corrosion resistance.
