dissolve 100 parts of industrial ammonium carbonate with 300 parts of 50 ℃ hot water, add appropriate amount of barium hydroxide according to the SO4 2-ion content in the raw materials, and stir all
Uniform, heat preservation at 50 ℃ for 1~2h. Pass pure ammonia into the filtered filtrate to saturation (the mouth of the airway should be close to the bottom of the solution, and the container should be covered to prevent excessive ammonia from escaping). Cool to about 10 ℃, let it stand fully, then empty the excess ammonia gas, and cool the ice water until the crystallization is complete. Quickly spin dry and crystallize after packaging. The reagent ammonium carbonate monohydrate is obtained. Mother liquor can be recycled.
