В насто щее врем очистку азота от кислорода производ т различными способами, иапример, пропусканием газа через щелочной раствор пирогаллола, над раскаленной медной свернутой сеткой, через медноаммиачныи раствор и т. д.At present, nitrogen purification from oxygen is carried out in various ways, for example, by passing gas through an alkaline pyrogallol solution, over a hot, coiled copper grid, through a copper-ammonia solution, etc.
Согласно изобретению предлагаетс очищать азот от кислорода до содержани кислорода в азоте 0,001 % и менее путем поглощени кислорода раствором медноаммиачной целлюлозы.According to the invention, it is proposed to purify nitrogen from oxygen to an oxygen content in nitrogen of 0.001% or less by absorbing oxygen with a solution of ammonium cellulose.
Сущность способа очистки азота от кислорода сводитс к следующему . В приготовленный обычным способом медно-аммиачный растворThe essence of the method of purification of nitrogen from oxygen is as follows. Copper ammonia solution prepared in the usual way

с содержанием меди от 12 до 15 и аммиака от 18 до 22% внос т до 5% целлюлозы. После того как целлюлоза растворитс , с помощью распылител пропускают азот. Содержание кислорода в азоте после очистки достигает 0,001 % и ниже.with a copper content of 12 to 15 and ammonia of 18 to 22%, up to 5% cellulose is introduced. After the cellulose is dissolved, nitrogen is passed through the nebulizer. The oxygen content in nitrogen after treatment reaches 0.001% and below.
Предмет изобретени Subject invention
Способ очистки азота от кислорода с применением аммиачного раствора окиси меди, отличающийс тем, что азот пропускают через раствор моно- или полисахаридов, например целлюлозы, в аммиачном растворе окиси меди.A method for purifying nitrogen from oxygen using an ammonia solution of copper oxide, wherein nitrogen is passed through a solution of mono- or polysaccharides, such as cellulose, in an ammonia solution of copper oxide.
