Description
Известен способ очистки ацетилена, нолучаемого из карбида кальци , от примеси фосфористых и серннстых соединений посредством 30- 40%-ного раствора азотной кислоты.A known method of purification of acetylene, obtained from calcium carbide, from the admixture of phosphorous and sulfur compounds by means of a 30-40% aqueous solution of nitric acid.
Описываемый способ очистки ацетилена, в отличие от известного, сокращает расход азотной кислоты. С этой целью, к раствору кислоты добавл ют азотнокислое серебро в количестве 0,005% (весовых).The described method of purification of acetylene, in contrast to the known, reduces the consumption of nitric acid. To this end, silver nitrate in an amount of 0.005% (by weight) is added to the acid solution.
Так, например, если при пропускании через 1 л 30%-ното раствора азотной кислоты ацетилена, содержащего 0,08% фосфористого водорода, проскок фосфористого водорода наблюдаетс после прохождени 12 л ацетилена, то согласно описываемому способу 1 л 30°/о-ного раствора азотной КИСЛОТЫ с добавкой 0,005Vo азотнокислого серебра количественно очищает 10 Л1 ацетилена (содержание фосфористого водорода в исходном газе составл ет 0,08%). Причем при указанной концентрации азотнокислого серебра не образуетс осадка ацетиленида серебра. Таким образом, введение в раствор азотной кислоты добавки в виде азотнокислого серебра в очень малых количествах повыщает эффективность очистки ацетилена в большое число раз.For example, if, when passing through a liter of a 30% solution of acetylene nitric acid containing 0.08% of phosphorous hydrogen, a slip of hydrogen phosphide is observed after passing 12 liters of acetylene, then according to the described method 1 liter of 30 ° / about solution nitric acid with the addition of 0.005Vo silver nitrate quantitatively purifies 10 L1 acetylene (the content of phosphorous hydrogen in the initial gas is 0.08%). Moreover, at the indicated concentration of silver nitrate, no silver acetylide precipitate is formed. Thus, the introduction of an additive in the form of silver nitrate in very small quantities into a solution of nitric acid will increase the efficiency of acetylene purification by a large number of times.
Азотнокислое серебро из отработанных растворов выдел етс обыч тыми приемами.Silver nitrate from spent solutions is excreted in the usual ways.
