Technology Process of Germanium

There total 67 articles about Germanium which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:
Guidance literature:
In hydrogen bromide; according to T.S. Piper, M.K. Wilson, J. Inorg. Nucl. Chem., 4, 22 (1957) and J.E.Griffiths, Inorg. Chem., 2, 375 (1963); collected into -134°C trap, purified by passing through a columnwith silica gel and mol. sieve 5A at -30 °C, detd. by chromy. and mass spectrometric analysis;
Guidance literature:
In solid matrix; byproducts: LiCl, AlCl3; distilling gaseous GeCl4 in vac. on solid matrix of LiAlH4 in ether (cooled with liq. N2), heating to room temp.;; fractional condensation at -111.9 °C;;
