ABSTRACT:
A process for production of unsymmetrical dimethylhydrazine from nitroso dimethylamine that is characterized as a completely closed system with respect to positive prevention of environmental contamination by waste nitrosodimethylamine. This process further provides a novel extraction step which also produces, as a solid by-product, potassium nitrate without nitrosodimethylamine contamination.
