Abstract
Regular equimolar deuterium-tritium is a mixture of 25 mol% T2-50% DT-25% D2. We have synthesized molecular DT of greater purity by the reaction LiT + CH3OD → DT + LiOCH3, run at 243 K. With both the alcohol and reactor-to-cryostat transfer lines at room temperature, we obtain 88 mol% DT purity. By cooling the alcohol and holding the transfer lines at 80 K, the yield rose to 95% DT. The DT disproportionated to D2 and T2 with a 1/e time constant of about 100 hr in the liquid at 20.5 K. Nuclear magnetic resonance data showed that the eventual T2-DT-D2 equilibrium is probably a “hot-atom” one.Keywords
