Reaction Conditions

Reaction Steps

To a solution of 210 g of hydrazine dihydrochloride in 2 liters of water there was added, in one portion, 224 g of citraconic anhydride. When the mixture was heated to boiling with stirring, a homogeneous solution was first obtained and then a white precipitate started to form in the mixture. After 30 minutes at reflux, the mixture was allowed to cool with stirring. It was then cooled to 10° C. and the solid was separated by filtration and dried in a vacuum oven overnight to give citraconic hydrazide melting at about 281-283.5° C. with decomposition.
