Friends of chemistry, how to synthesize ethylenediamine sulfate? What should I pay attention to? Thank you very much.

There are many ways to synthesize ethylenediamine sulfate. The following is one of the conventional methods: mix two moles of ethylenediamine and 1 mole of sulfuric acid at a proper temperature: C2H8N2+H2SO4 → (NH4) 2SO4+C2H10n2s. It should be noted that the reaction temperature and time should be strictly controlled during the reaction to avoid by-products or incomplete reaction. In addition, a large amount of sulfuric acid vapor and toxic gas may be produced during the reaction, so good ventilation conditions and necessary safety measures must be ensured during the operation.
