Description
г. в. Акимов, В, П. Батраков и Г. А. Маргулис ИНГИБИТОР ДЛЯ КОНЦЕНТРИРОВАИНОЙ АЗОТНОЙ КИСЛОТЫc. Akimov, V, P. Batrakov, and G. A. Margulis INHIBITOR FOR CONCENTRATING NITRIC ACID
За влено 18 июн 1947 г. за Л 0953 в Бюро по делам изобретательстваFiled on June 18, 1947 for L 0953 to the Bureau of Invention
-Министерства Вооружени СССР Опубликовано в «Бю.1.1етснс изобретений ЛЕ 20 .на J959 г.-Ministry of Arms of the USSR Published in "Bu.1.1tstsn inventions LE 20 .na J959
Изобретение относитс к ингибиторам коррозии азотной кислоты.This invention relates to nitric acid corrosion inhibitors.
Известными ингибиторами азотной кислоты вл ютс сульфатизированный клей, уротропин, пиридин и другие.Known nitric acid inhibitors are sulfated glue, hexamine, pyridine and others.
Насто щее изобретение предусматривает применить в качестве ингибиторов мышь ковистый ангидрид в количестве 0,05-0,3% по отношению к кислоте или смесь мышь ковистого ангидрида с окислами сурьмы или хрома в количестве до 0,5% по отношению к кислоте.The present invention provides for use as a inhibitor mouse, a malignant anhydride in an amount of 0.05-0.3% with respect to acid, or a mixture of a mouse with malleus anhydride with oxides of antimony or chromium in an amount up to 0.5% with respect to acid.
Преимуществом такого ингибитора вл етс то, что данный ингибитор позвол ет снизить скорость коррозии в 100-200 раз-Изобретение позвол ет также хранить азотную кислоту в сосудах, сделанных из обычной углеродистой малолегированной стали.The advantage of such an inhibitor is that this inhibitor can reduce the corrosion rate by 100–200 times. The invention also allows storing nitric acid in vessels made of ordinary low alloyed carbon steel.
Предмет изобретени Subject invention
Ингибитор дл концентрированной азотной кислоты, содержащейс Е стальных металлических оболочках, отличающийс тем, что к указанной кислоте добавл ют 0,05-0,3% мышь ковистого ангидрида или смесь его с окислами сурьмы или хрома в количестве до 0,5%.Inhibitor for concentrated nitric acid containing E steel metal shells, characterized in that 0.05-0.3% of mouse malleus anhydride is added to this acid or its mixture with oxides of antimony or chromium in an amount up to 0.5%.
