実験手順
A mixture of 146 g (1.1 moles) of N-(2-amino-2-methylpropyl)-1,2-ethanediamine, 84.4 (1.17 moles) of 2-butanone, 300 ml methanol, and 3.0 g of 10% platinum on carbon were reacted in a 1 liter autoclave at 80° C. under 800 pounds per square inch (psi) hydrogen pressure. After two hours the reaction mixture was cooled, then filtered to remove the catalyst. The filtrate was stripped to give 205.3 g of water-white clear liquid which was fractionally distilled under reduced pressure. The desired product recovered was found to weigh 144.5 g (69.5% yield), and has a boiling point (b.p.) of 62°-64° C./0.15 mm Hg.
