Abstract: Process for the production of TEMDA in high yield by reducing 2,3-dimethyl-2,3-dinitrobutane with hydrogen in the presence of a chromium promoted Raney cobalt catalyst. A solution of 2,3-dimethyl-2,3-dinitrobutane in a suitable solvent is fed to a reactor while avoiding the accumulation of 2,3-dimethyl-2,3-dinitrobutane in the reaction medium, such as by feeding it at a rate no greater than its rate of reaction with hydrogen. In a preferred embodiment, the resulting TMEDA is recovered by converting it to an amine salt by sparging carbon dioxide through the solution.
