unsym-Dimethylhydrazine - Preparation Method
Open Data Verified Data
This product can be ammonia, ammonium chloride and dimethylamine as raw materials by reaction synthesis. First, ammonia water and sodium hypochlorite are sent to a one-step reactor for reaction to generate chloroamine, and then the chloroamine is sent to a two-step reactor for synthesis with dimethylamine aqueous solution to generate unsymmetrical dimethylhydrazine aqueous solution, then, the synthesis liquid is sent to a series of rectification columns for further distillation and rectification to remove excess ammonia, dimethylamine and partial hydrazone. After concentration and degassing with alkali, the finished product is obtained.
