摘要：
Neodecanoic acid diamides were prepared by a simple one-step procedure involving condensation of neodecanoic acid with diethylenetriamine, triethylenetetramine, and pentaethylenehexamine. The inhibiting effect of these diamides on the corrosion of St3 low-carbon steel in 2. H2SO4 and in 1 and 5. HCl was studied gravimetrically. All the compounds synthesized efficiently inhibit the steel corrosion with the degree of protection at room temperature of 94-95% in 2. H2SO4 and 96-97% in 1. HCl.
