Synthesis of Hydroxy Aminimide from Unsymmetric Dimethyl Hydrazine Through One Pot Reaction: A New Nanoscale Access for the Reutilization of Unsymmetrical Dimethyl Hydrazine

In this paper, two new kinds of hydroxy aminimide were nanoscale synthesized utilizing Unsymmetrical dimethyl hydrazine (UDMH) and economical carboxylic acid methyl ester was analyzed through one pot reaction. The reaction conditions were examined and the best reaction temperature was 20 °C with the reaction time of 60 h, achieving a highest yield of 83.21% for the two aminimides. Structures of the final products are characterized by GC-MS, FT-IR and NMR. Then the thermal stability of the aminimide is tested and it is found that the decomposition temperature of one aminimide is 65.20 °C, which is better than any other aminimides used for the latent curing agent of epoxide resin.
