energetic properties as well, namely for propulsion applications. A novel and scalable synthesis has been developed for a new family of bishydrazines, starting from monomethylhydrazine (MMH). This solvent‐free route represents a suitable alternative to the one described in the literature. It was extended to design a new family of unsymmetrical hydrazines bearing various functional groups. A selected
功能化的肼和双肼是获得较高含氮化合物的有趣且直接的前体。它们还提供结构多样性和有希望的能量特性,即用于推进应用。从一甲基肼(MMH)开始,已经开发了一种新颖且可扩展的合成用于新的联肼家族。这种无溶剂方法是文献中所述方法的一种合适替代方法。它被扩展为设计一个带有各种官能团的不对称肼的新家族。选定的一系列有前途的化合物,经硝化的基团(氨基,肼基或叠氮基官能团)致密化,被认为是一类可能的液体推进剂。确实,通过在双推进剂系统中计算肼的形成热和比冲值,证明了这种肼的积极性。这导致了与MMH / N相当的理论能量表现今天已经在使用2 O 4系统。
