Synthese

About 150 ml. of n-butyl ether, dried over Na, is distilled into the reaction flask and 5.75 g. of LiAlH4 (40% excess) is then added under a nitrogen blanket. The mixture is frozen with liquid N s. The apparatus is then evacuated, and the flask contents are brought to boiling by careful heating. After 1.5 hours, it is again cooled with liquid Ns , the evacuation is repeated, and 5 ml. of 99.5% D2O is added to the solidified mixture, using a hypodermic syringe to pierce the rubber cap. Because of the low reaction temperature, the flask becomes coated with ice on the outside. By repeated immersion in liquid N3, the temperature is controlled so that the ice on the outer wall of the flask does not melt. As soon as the reaction subsides somewhat, two additional portions of 6.5 ml. of DSO each are added (for a total of 18 ml. or 150% excess). The yield is 10 liters of HD. The purity is 97-99%.
LiAlH₄ + 4D₂O = LiOD + Al(OD)₃ + 4HD
