All double displacement reactions have the general form: When a double displacement reaction occurs, the cations and anions switch partners, resulting in the formation of two new ionic compounds AD and CB, one of which is in the solid state.
Discuss Abstract The invention relates to methods for coproducing sodium carbonate and ammonium sulfate from melamine tail gas and mirabilite. The method for producing the sodium carbonate comprises the following steps of: The method further comprises the following steps of: The methods have the advantages of high utilization rate of raw materials and low energy consumption.
Using the method of the invention, the feedstock for the process is for all of the melamine off-gas of the present invention may be co-production of 1 t 2.
