Synthesis of ethyleneimine dimer

This invention provides a method for synthesizing ethyleneimine dimer which includes reacting 2-(2-aminoethylamino)ethanol with an aqueous HX solution to produce N-(2-haloethyl)-1,2-ethanediamine dihydrohalide; reacting this product with a base in a solvent to convert the N-(2-haloethyl)-1,2-ethanediamine dihydrohalide into ethyleneimine dimer; and purifying the dimer from the solvent. This method of synthesis provides several advantages over previous methods: (1) The starting compounds are all relatively inexpensive; (2) the yield of the product is greater than 20% of the theoretical yield; and (3) the steps of the synthesis are easy, inexpensive and amenable to large-scale production. All of these advantages allow for less expensive production of ethyleneimine dimer.
