Description
Изобретение относитс к химии и технологии соединений азота, в частности к способу получени окиси азота .This invention relates to the chemistry and technology of nitrogen compounds, in particular, to a process for the production of nitric oxide.
Целью изобретени вл етс noafci- шение выхода продукта и повьшение его концентрации в газовой смеси.The aim of the invention is to noafci the output of the product and increase its concentration in the gas mixture.
Согласно предлагаемому способу процесс протекает по уравнениюAccording to the proposed method, the process proceeds according to the equation

Пример. К раствору 40 г нитрита натри в 60 мл воды прикапывают при перемешивании и температуре 15- ZO C смесь 42 мл серной кислоты (,40 г/см) и 12 мл 40%-ного формалина . Образующийс газ очищают от двуокиси углерода, пропуска через раствор щелочи. Выход газа 12,6 л (97% от теоретического). По данным анализа двуокись углерода отсутствует . Содержание окиси азота 93,9%.Example. To a solution of 40 g of sodium nitrite in 60 ml of water is added dropwise with stirring at a temperature of 15-ZO C a mixture of 42 ml of sulfuric acid (40 g / cm) and 12 ml of 40% formalin. The resulting gas is purified from carbon dioxide by passing through an alkali solution. The gas yield of 12.6 liters (97% of theoretical). According to the analysis of carbon dioxide is missing. Nitric oxide content is 93.9%.
Экспериментально установлено, что при иной, чем в примере, последовательности смещени ко1 1понентов концентраци окиси азота в полученном газе не превышает 30-60 об.%.It was established experimentally that with a different sequence than in the example, the sequence of the shift of the components, the concentration of nitric oxide in the resulting gas does not exceed 30-60% vol.
