ABSTRACT:
Tetramethylethylenediamine is prepared by reacting 1,2-dichloroethane with an excess of dimethylamine at elevated temperatures and pressures. The process is carried out continuously in the presence of water and the amines in the reaction product are liberated by treatment with bases. Unconverted dimethylamine is separated and treated with water and then recycled into the reaction.
