Preparation of benzene-d6

Preparation of benzene-d6

Pure benzene is carefully dried over phosphorus pentoxide, then distilled into deuterium sulfate, and the mixture is shaken for 3-4 days, after which the benzene is distilled off in a vacuum into a fresh batch of deuterium sulfate. After four repetitions of these operations the benzene is transferred to a flask containing roasted barium oxide, after 12 hours to a flask containing phosphorus pentoxide, and after a further 15 min to a storage flask. The benzene-d6 obtained contains 99.8% of deuterium. For the same reaction phosphoric acid-d3 (D3PO4) is less powerful, in the other hand, deuterium chloride containing aluminum chloride is a more powerful reagent than deuterium sulfate; equilibrium is established already after 3 hours at 25° C if deuterium chloride is led into a suspension of aluminum chloride in benzene; 40 hours suffice for obtaining 36 ml of benzene-d6 containing 99.3% of deuterium.
