Preparation of formic acid-d2

Preparation of formic acid-d2

10 g of anhydrous oxalic acid are recrystallized three times from 9 ml of deuterium oxide, the crystals being purified each time by sublimation at ca. 1 mm. Then obtained oxalic acid-d2 is pyrolyzed by being sublimed at ca. 1 mm through a 10-inch column filled with glass pieces and heated at 220° C. The formic acid-d2 formed is collected yielding 2.2 g from 8.8 g of oxalic acid-d2, i.e., 98%; b.p. 44-44.5°C/58 mm; nD= 1.3692 (at 20° C).
