More Information
Summary:The invention discloses a preparation method of lithium amide, and relates to the technical field of material synthesis. The preparation method comprises the following steps: replacing air in a flask with argon to form an inert atmosphere, adding metal lithium particles with the particle size of 0.1-10mm into the flask, adding a solvent, starting stirring at the stirring speed of 200-800r/min at the reaction temperature of 0-50 DEG C, slowly introducing ammonia gas, gradually dissolving the metal lithium in the solution, and performing ammonification reaction on the metal lithium to form an oily substance Li (NH3) 4; isoprene is dropwise added, in the dropwise adding process, oily matter becomes gray solid and suspends in the solution, and after dropwise adding is completed, the gray solid becomes white solid; and filtering to obtain white powdery solid lithium amide. The method has the advantages that by controlling the size of metal lithium particles and changing the stirring speed, the reaction is carried
