Versuchsvorschrift
A 1 liter autoclave was charged with a mixture of acetonitrile (61.5 g, 1.5 moles), ISOPAR-M (300 g), and the wetting agents (7.5 g each). The mixture was pressurized with nitrogen and heated to 150° C. Melted phosphorous acid (246 g, 3.0 moles) was pumped into the reactor through 15 minutes. The reaction was continued for 3 hours, maintaining the temperature at 150° C. Water (300 g) was pumped in and the product was collected after cooling. Colorless crystals of 1-amino-1,1-diphosphono ethane was obtained as fine grains, 76% yield.
