Description

этом через раствор пропускают ток хлористого водорода. По мере протекани  реакции идет расслаивание раствора. Когда нижний слой составит 1/4 объема, подачу хлорис того водорода прекрашагот. Реакци  продолжаетс  до исчезновени  нижнего сло ,. Раствор фильтруют и упаривают до 100 мл.Выпавшие кристаллы отфильтровывают и помещают в абсолютный диэтиловый эфир( 250мл) И нагревают до 36 С в течение 5-6 час. Образевавшийс  белый порошок хлорида магни  отфильтровывают, промывают эфиром и сушат.This is passed through a solution of a current of hydrogen chloride. As the reaction proceeds, the solution is stratified. When the bottom layer is 1/4 of the volume, the supply of chlorine to that hydrogen is stopped. The reaction continues until the bottom layer disappears,. The solution is filtered and evaporated to 100 ml. The precipitated crystals are filtered and placed in absolute diethyl ether (250 ml) and heated to 36 ° C for 5-6 hours. The resulting white powder of magnesium chloride is filtered off, washed with ether and dried.

Маточники после фильтрации и промывки объедин ют и при температуре О в течение 3-4 час насыщают хлористым водородом Затем в этот раствор загружайзт 1,6 г металлического магни  и синтез продолжаютAfter filtration and washing, mother liquors are combined and saturated at 3 ° C with hydrogen chloride. Then 1.6 g of metallic magnesium is loaded into this solution and the synthesis is continued

согласно описанному выше.as described above.
