Abstract
Изобретение относится к новому способу синтеза оксида азота(IV) NOи может быть использовано в неорганической и органической химии. При получении оксида азота(IV) NOосуществляют реакцию между азотной и уксусной кислотами в среде концентрированной серной кислоты при оптимальном соотношении 40:6:80 по объему или в интервале отношения объемов кислот (30-70):(4-120):(80-160) соответственно при температуре кипения раствора. Оксид азота(IV) NOсобирают в ловушке с температурой (-5)-(20)°С или не осуществляют конденсацию. Выход оксида азота(IV) NOдостигает 90% при полной конверсии азотной кислоты. Дополнительную очистку оксида азота(IV) NOосуществляют простой перегонкой. Отработанный раствор упаривают до концентрации 85-97% по серной кислоте и используют повторно в реакции. Изобретение пригодно для создания генератора оксида азота(IV) NO.The invention relates to a new method for the synthesis of nitric oxide (IV) NO and can be used in inorganic and organic chemistry. Upon receipt of nitric oxide (IV) NO, the reaction between nitric and acetic acids is carried out in a medium of concentrated sulfuric acid at an optimal ratio of 40: 6: 80 by volume or in the range of the ratio of volumes of acids (30-70) :( 4-120) :( 80- 160) respectively at the boiling point of the solution. Nitrogen oxide (IV) NO is collected in a trap with a temperature of (-5) - (20) ° C or does not condense. The yield of nitric oxide (IV) NO reaches 90% with full conversion of nitric acid. Additional purification of nitric oxide (IV) NO is carried out by simple distillation. The spent solution is evaporated to a concentration of 85-97% for sulfuric acid and reused in the reaction. The invention is suitable for creating a generator of nitrogen oxide (IV) NO.
