Application
Diethyl azodicarboxylate is a liquid blowing agent; a pharmaceutical intermediat. Diethyl azodicarboxylate is also used for vinyl resin liquid foaming agent and be used to make light color vinyl foamed plastics. Have uniform microporous structure, with the recipe and processing conditions are different, can get shut holes or the openings foam body. Also used as medicine intermediates, organic synthetic reagent, etc.
Purification Methods
Dissolve DEAD in toluene, wash it with 10% NaHCO3 till neutral (may require several washes if too much hydrolysis had occurred: check IR for OH bands), then wash with H2O (2x), dry over Na2SO4, filter, evaporate the toluene and distil it through a short Vigreux column (p 11) at as high a vacuum as possible. The main portion boils at 107-111o/15mm. Since it is likely to explode, use an oil bath for heating the still and all operations should be carried -out behind an adequate shield.
