Reaction Conditions

Reaction Steps

A mixture of 67.5 g of hydrazine hydrate (1.35 moles), 60 g of toluene and 290 g of propylene carbonate (2.8 moles) was heated to 90° C. for 2 hours. The water in the system was removed by azeotropic distillation with toluene under reduced pressure (water aspirator). The excess propylene carbonate (108 g) was removed by vacuum distillation to afford a mixture of the 1:1 and 2:1 propylene carbonate/hydrazine adducts. By calculation the product was present in an approximately 70/30 ratio on a molar basis and an approximately 55/45 ratio on a weight basis of the 1:1 and 2:1 adducts.
