Abstract : A process for extracting essentially pure unsymmetrical dimethyl hydrazine (UDMH) from a solution containing UDMH, water, and other volatiles and nonvolatiles, comprises charging a distillation stillpot with the UDMH solution, mixing into the solution sufficient caustic sodium hydroxide so as to cause the solution to separate into a two layer system, mixing isopropanol into the two layer system, and distilling off the essentially pure UDMH distillate.
