Technology Process of Gold trifluoride

There total 12 articles about Gold trifluoride 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:

Reference yield: 65.0%

gold (7440-57-5,457905-15-6) + fluorine (7782-41-4) → gold(III) trifluoride (14720-21-9)

Guidance literature:

In neat (no solvent); (anhydrous conditions); condensing F2 at -196°C into a quartz tube containing a gold wireg, warming to r.t., to start the reaction heating the bottom of the vessel 10 s to 880°C, after the exothermic reaction cooling the vessel to r.t.; pumping off the volatiles at 20°C, transfer into a Pyrex ampoule which is flame-sealed; elem. anal.;

Reference yield:

bromine trifluoride (7787-71-5) + bromine fluoride (13863-59-7) + gold (7440-57-5,457905-15-6) → gold(III) trifluoride (14720-21-9) + bromine (7726-95-6)

Guidance literature:

In neat (no solvent); (N2), 20°C; Kinetics;

Reference yield:

silver fluoride (11113-87-4) + gold(III) chloride (13453-07-1) → gold(III) trifluoride (14720-21-9)
