Description
Известны способы очистки окиси азота от высших окислов улавливанием последних жидкими поглотител ми, например растворами щелочей .Methods are known for purifying nitric oxide from higher oxides by trapping the latter with liquid scavengers, for example, alkali solutions.
Эти способы недостаточно просты и не позвол ют получить окись -азота высокой степени чистоты, так как при взаимодействии с щелочалш происходит образование значительного количества (до 30%) закиси азота.These methods are not simple enough and do not allow obtaining high purity oxide-nitrogen, since the interaction with alkalis leads to the formation of a significant amount (up to 30%) of nitrous oxide.
Ло предлагаемому способу, с целью упрощени процесса и повышени степени очистки окиси азота, в качестве жидкого поглотител используют дистиллированную воду.In the proposed method, in order to simplify the process and increase the degree of purification of nitric oxide, distilled water is used as a liquid absorber.
Процесс очистки окиси азота осуществл ют барботированием через промывную скл нку, заполненную дистиллированной водой. Дл увеличени эффекта очистки дистиллированную воду следует деаэрировать, напри.мер, кип чением или вакуу.мированием.The process of purification of nitric oxide is carried out by bubbling through a washing flask filled with distilled water. To increase the cleaning effect, distilled water should be deaerated, for example, by boiling or vacuuming.
Результаты масс-спектроскопического анализа окиси азота, очищенной в соответствии с предлагаемым способом, показывают, что степень ее чистоты достигает 99,9%, в то врем как при очистке раствором щелочи она содержит до 43% примесей.The results of mass spectroscopic analysis of nitric oxide, purified in accordance with the proposed method, show that its purity reaches 99.9%, while it contains up to 43% of impurities when cleaning with an alkali solution.
Применение воды по предлагаемому способу вместо раствора щелочи упрощает и удещевл ет процесс очистки и дает возможность повысить степень очистки до 99%.The use of water by the proposed method instead of an alkali solution simplifies and simplifies the cleaning process and makes it possible to increase the degree of purification up to 99%.
Предлагаемый способ отличаетс простотой, экономичностью, и на его основе может быть разработан технологический процесс производственной очистки окиси азота.The proposed method is simple, economical, and on its basis a technological process for the production purification of nitric oxide can be developed.
