We adopt Hydrazine Hydrate method in the process of manufacturing Methylhydrazine, there is no Ethylhydrazine and UDMH,the Particulate matter was less than

7mg/L,Amine Wt% was less than 0.1%,ChloridesWt% less than 0.005%, Hydrazine Wt% was less than 0.1%.

Methylhydrazine is a valuable starting material for the preparation of crop protection agents and pharmaceuticals.

Manufacturing Method:

MMH is prepared from reation of Methanol  and Hydrazine Hydrate at elevated pressure: 0.7——1.3Mpa 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  control.
