FIELD: organic chemistry, anticorrosive substances.
SUBSTANCE: invention relates to a method for protection members, machines, constructions and buildings made of carbonic and low-alloyed steels against corrosion that in the exploitation process contact with aqueous solutions of salts, acids, industrial and domestic-sewage waters, sea water and wetted soils also. Method involves addition of inhibitor wherein aminoester salt is used as inhibitor of the general formula: 
wherein R means -CH2C6H5; -CH(C6H5)2; -CH(C6H5)3; -CH2CH3; -CH(CH3)2; -C(CH3)3; R' means -CH3; -C2H5; -C3H7; -OC2H5; -OC3H7; R'' means 2HCl; 2HBr; HCl.HBr; 2HF; HCl.HF; HBr.HF. Invention provides preparing inhibitor of corrosion combining properties of biocide and inhibitor of hydrogen absorption steel simultaneously, progressive reducing the steel corrosion rate with the increasing concentration of added organic substance.
EFFECT: improved method of steel protection, valuable properties of inhibitor.
