Beschreibung
Zusammenfassung:	FIELD: corrosion protection.SUBSTANCE: invention relates to the problem of protecting structures operated in water containing corrosive ions. In particular, sodium salts of α-branched C-C-monocarboxylic acids are proposed as corrosion protectors for perlite steels in presence of aluminum alloys in natural waters at elevated (20-140°C) temperatures under effect of neutron stream (up to 10neutrons/cm).EFFECT: enhanced protective properties and extended temperature range for use of corrosion inhibitor.3 tbl Изобретение относится к области защиты конструкций в воде, содержащей агрессивные ионы. Применение технической фракции α-разветвленных натриевых солей монокарбоновых кислот состава С-Св качестве ингибитора коррозии перлитных сталей в присутствии алюминиевых сплавов в природных водах при повышенных температурах 20-140°С и воздействии нейтронного потока (до 10нейтрон/см). Технический результат заключается в повышении защитных свойств и расширении температурного предела применения ингибитора коррозии. 3 табл.
