The method of producing steel corrosion inhibitors in hydrogen sulfide-containing environments based on the products of diethylene glycol amination of the general formula H (-NH-CH-CH-O-CH-CH-) R, where R is -NH, -OH, n = 2-4, characterized in that, in order to improve the properties of steel corrosion inhibitors in hydrogen sulfide-containing environments at low concentrations, diethylene glycol is reacted with ammonia in the presence of hydrogen and a heterogeneous nickel-zirconium catalyst composition, wt.%: ZrO- 5 - 95Ni - 95-5: 150 - 270C. |
