실험 절차
A mixture of cyanoacetic acid (4.3 g, 0.5 mole), phosphorous acid (8.2 g, 0.1 mole), ISOPAR-M (20 g), and the wetting agents (0.25 g each) was heated at 165° C for 2 hours. The product was worked up with acetone to get yellow crystals of 1-amino-1,1-diphosphono-2-carboxy ethane, m.p. 255° C (decomposition), 55%, associated with traces of impurities.
