Description
Известен способ очистки газов, например водорода, азота, аргона, от кислорода и влаги путем пропускани газа через химический реагент, например щелочной металл, который реагирует с кислородом и водой очень быстро, образу нелетучие продукты - окись или гидроокись. Поэтому следы кислорода и влаги из газа мож но удал ть пропусканием его через жидки при комнатной температуре сплав натри кали . Остаточное содержание примеси во ды и кислорода зависит от скорости потока газа, проход щего через сплав. Однако при этом быстро уменьшаетс активна поверхность металла вследствие образовани окиси, преп тствующей контактированию с газом, что приводит к не полному использованию щелочного металла и снижению интенсивности процесса очистки. -. Цель изобретени - интенсифицировать процесс. Это достигаетс тем, что в качестве химического реагента используют раствоI римые комплексы щелочных металлов с полиароматическими углеводородами в среде простых эфиров. Истинные растворы щелочных металлов целесообразно готовить в мол рном соотнощении к полиароматическому углеводороду 1:1. Предлагаемый способ очистки прост и технологически может быть исполнен в непрерывном варианте. Пример. В колбу емкостью 1 л (с коническим основанием) внос т 15,4 г дифенила и раствор ют в 1ОО мл абсолютного свежеперегнанного тетрагидрофурана. Затем прибавл ют 2,3 г очищенного от оксидной пленки мелконарезанного натри и смесь выдерживают в течение 8-12 час до полного растворени щелочного металла . Образование комплекса щелочного металла с дифенилом в среде тетрагидрофу- рана сопровождаетс окрашиванием раствора в интенсивный сине-зеленый цвет. Процесс существенно ускор етс при перемешивании смеси. После разбавлееш полученной смеси еще 40О мл тетрагидрофурана раствор перенос т в промывалкуA known method of purifying gases, for example hydrogen, nitrogen, argon, from oxygen and moisture by passing a gas through a chemical reagent, for example an alkali metal, which reacts with oxygen and water very quickly to form nonvolatile products such as oxide or hydroxide. Therefore, traces of oxygen and moisture from the gas can be removed by passing it through liquid at room temperature sodium potassium alloy. The residual impurity content of water and oxygen depends on the flow rate of the gas passing through the alloy. However, the active metal surface is rapidly reduced due to the formation of oxide, which prevents contact with the gas, which leads to an incomplete use of alkali metal and a decrease in the intensity of the cleaning process. -. The purpose of the invention is to intensify the process. This is achieved by using soluble alkali metal complexes with polyaromatic hydrocarbons in ether medium as a chemical reagent. True alkali metal solutions should be prepared in a molar ratio of 1: 1 polyaromatic hydrocarbon. The proposed cleaning method is simple and technologically can be executed in a continuous version. Example. 15 ml of diphenyl are introduced into a 1 liter flask (with a conical base) and dissolved in 100 ml of absolute freshly distilled tetrahydrofuran. Then, 2.3 g of finely cut sodium removed from the oxide film is added and the mixture is kept for 8-12 hours until the alkali metal is completely dissolved. The formation of an alkali metal complex with diphenyl in tetrahydrofuran medium is accompanied by staining the solution in an intense blue-green color. The process is significantly accelerated by stirring the mixture. After diluting the resulting mixture with another 40 O ml of tetrahydrofuran, the solution is transferred to a wash.
