Formylhydrazine Uses
Formohydrazide (CAS NO.624-84-0) is used in organic synthesis.
Formylhydrazine Production
Be careful to join the 85% hydrazine hydrate and 95% ethyl alcohol solution,stirring 10min. When the relaxation response,making the reaction solution refluxed 18h, vacuuming steam out of most of the water and ethanol.It was tilting crude syrup, and further refined to be finished formyl hydrazine.
