Reaction Steps

To a 250 ml Erlenmeyer flask was added 7.9 g (0.1 mole) ammonium bicarbonate, 2.01 g (0.05 mole) magnesium oxide, 100 ml distilled water, 4.9 g (0.1 mole) sodium cyanide. The mixture was stirred and 8.1 g (0.1) mole of a 37% solution of formaldehyde was added dropwise over 2 minutes. The mixture was stirred and let stand overnight. Then an additional 50 ml of water was added and 2.0 g magnesium oxide while carbon dioxide was bubbled through the mixture. A total of 11.5 g of carbon dioxide was added. The mixture was filtered and the filtrate evaporated to near dryness on a hot plate. A crude product of magnesium glycine carbamate was obtained (11.52 g) having an alkalinity value of 694 and containing 6.2% magnesium, 855 ppm calcium, 1.7% sodium and 9.8% nitrogen.
