Manufacturing Method: Our MMH is prepared from reation of Methanol and Hydrazine Hydrate at elevated pressure: 0.7__1.3Mpa(illion Pascal) through catalytic treatment with Dichloromethane and hydrochloric acid. MMH is removed by distillation from the reaction mixture in a low boiler fraction and this low boiler fraction is optionally subjected to a rectification. Methanol and hydrazine hydrate were recycled through technological operation and system control.
