Ингибитор относится к защите коррозионно-стойких металлов от коррозии, в частности к методу защиты нержавеющих сталей и титана от коррозии в безводных уксусно-кислых средах, например при их использовании в реакциях органического синтеза. Ингибитор коррозии для безводных уксусно-кислых сред, включающих фосфат, отличается тем, что в агрессивную среду добавляют 0,015 - 0,06М композиции, содержащей, мол.%: фосфат - 33 - 89 и N-ацетилфенилаланин - 11 - 67, причем в качестве фосфата может быть использована фосфорная кислота или ее растворимые соли.The inhibitor relates to the protection of corrosion-resistant metals from corrosion, in particular to the method of protecting stainless steels and titanium from corrosion in anhydrous acetic acid media, for example, when used in organic synthesis reactions. The corrosion inhibitor for anhydrous acetic acid media, including phosphate, is characterized in that 0.015-0.06 M compositions containing, mol%: phosphate - 33 - 89 and N-acetylphenylalanine - 11 - 67 are added to the aggressive phosphate can be used phosphoric acid or its soluble salts.
