Technology Process of Disulfur decafluoride

There total 23 articles about Disulfur decafluoride 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: 87.0%

fluorine (7782-41-4) + sulfur (7704-34-9) → disulfur decafluoride (5714-22-7) + disulfur difluoride (13709-35-8) + sulfur tetrafluoride (7783-60-0) + hydrogen fluoride (7664-39-3,12381-92-9,32057-09-3,74835-82-8) + sulfur(VI) hexafluoride (2551-62-4)

Guidance literature:

In neat (no solvent); byproducts: OF2; introduction of F2 into steel chamber, sulfur in compartments; detailed description of apparatus and handling given;; first passing through Ni (or Monel) tube (400°C); second Cu column (H2O sprayed); passed into steel column (containing carbon/Fe shavings; aq. NaOH sprayed); dried in column (containing solid NaOH, BaO or P2O5);;

Reference yield: 49.0%

(1,2-dibromotrifluoroethyl)pentafluorosulfur(VI) (22687-88-3) → fluorosulfonyl fluoride (640723-20-2,2699-79-8,12769-73-2) + disulfur decafluoride (5714-22-7) + 1,2,2-tribromo-1,1,2-trifluoroethane (354-49-4) + silicon tetrafluoride (7783-61-1) + thionyl fluoride (7783-42-8)

Guidance literature:

Irradiation (UV/VIS); irradiated (Hanovia S 500 lamp) in silica ampule, 20 h, further products;

Reference yield:

tetrakis(pentafluorosulfanyl)hydrazine → disulfur decafluoride (5714-22-7)
