실험 절차
A mixture of 21.03 g (0.24 mol) of γ-butyrolactone and 1.31 g (24 mmol) of ammonium chloride in 114.5 g (0.98 mol) of 1,1,1-tris(aminomethyl)ethane was heated at 250° C. in an autoclave. After 1.5 h, the mixture was cooled and the excess amine and the water formed were removed by distillation. The residue was distilled at 200°-240° C./18 mbar. The yield was 22.0 g (54%) of yellowish oil. The boiling point was 117°-120° C./1 mbar. Other data concerning the product was:
