Description
Изобретение относитс к способу получени боразола, который может быть использован в качестве исходного продукта при синтезе борорганических соединений в препаративной. химии и в радиометрических приборах, как индикаторный газ дл нейтронов.The invention relates to a process for the preparation of borazole, which can be used as a starting material in the synthesis of organoboron compounds in preparative. chemistry and radiometric devices, as an indicator gas for neutrons.
Известен способ получени боразола путем нагревани смеси боргидрида лити с хлористым аммонием в присутствии измельченного стекла перикс при температуре 220-300СA method of producing borazol is known by heating a mixture of lithium borohydride and ammonium chloride in the presence of crushed perix glass at a temperature of 220-300 ° C.
Дл упрощени способа предлагаетс в качестве боргидрида щелочного металла использовать боргидрид натри и процесс нагревани проводить при интенсивном истирании реагентов.To simplify the process, it is proposed to use sodium borohydride as the alkali metal borohydride and to carry out the heating process with intensive abrasion of the reactants.
При осуществлении этого способа температура процесса понижаетс до 150-230°С. Дл процесса используют менее дефицитный реагент.When implementing this method, the process temperature is reduced to 150-230 ° C. A less deficient reagent is used for the process.
. П Р и м е р. Во вращающийс стальной реактор объемом 0,7 л, заполненный на 50% истирающей насадкой. PRIMER. A 0.7 l rotating steel reactor filled to 50% with an abrasive nozzle
в виде металлических пиров, загружают 12 г боргидрида натри и 18 г сухого хлористого аммони .in the form of metal peers, 12 g of sodium borohydride and 18 g of dry ammonium chloride are loaded.
Реактор герметизируют, откачивают атмосферный воздух до остаточного давлени 0,1 мм рт.ст. и нагревают сначала до температуры 150 С, а затем через 0,5-1 ч до 200-230 С. Образующиес газообразные продукты реакции нагревают в охлаждаемле жидким азотом ловушки-конденсаторы, в которлх отдел ют боразол от водорода . Выход боразола 23%.The reactor is sealed, atmospheric air is evacuated to a residual pressure of 0.1 mm Hg. and firstly heated to a temperature of 150 ° C, and then in 0.5-1 hours to 200-230 ° C. The resulting gaseous reaction products are heated in cooled with liquid nitrogen, traps-condensers, in which borazole is separated from hydrogen. The output of borazole 23%.
