反応手順
Employing the reaction equipment and general procedures described in Example I, a solution of 229.0 g. (3.75 moles) monoethanolamine and 225.0 g. (3.75 moles) ethylenediamine was admixed with 6.25 g. (0.054 mole; 2.3wt.% and 1.44 mole%, basis MEA) 85% phosphoric acid and heated at 250° C. under 225 - 225 psig pressure for 2.0 hours. Analysis of the reaction product by gas-liquid chromatography (GLC Area %) showed a total conversion of reactants of only 4.7% was obtained. The reaction products were 95.0 diethylenetriamine, 2.5 piperazine and 2.5 Area % N-(2-aminoethyl)-ethanolamine. No higher polyethylene polyamines, e.g., triethylenetetramine, tetraethylenepentamine, etc. were formed.
