Technology Process of Chlorine monoxide

There total 59 articles about Chlorine monoxide 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: 76.0%

sodium nitrate (7631-99-4) + chlorine monofluoride (7790-89-8) → hypochlorous anhydride (7791-21-1) + chlorine nitrate (14545-72-3) + nitrylfluoride (10022-50-1)

Guidance literature:

In neat (no solvent); byproducts: NaF; mixt. of NaNO3 (excess) and ClF in a stainless steel cylinder allowed to warm slowly in a dry-ice-liquid N2 slush bath from -196°VC to -78 and then toward 0°C, recooled to -196°C; fractional condensation;

Reference yield: 60.0%

sodium nitrate (7631-99-4) + chlorine monofluoride (7790-89-8) → hypochlorous anhydride (7791-21-1) + chlorine nitrate (14545-72-3) + FClO2 (13637-83-7)

Guidance literature:

In neat (no solvent); byproducts: Cl2, NaF; finely powdered NaNO3 loaded into a stainless steeel cylinder, ClF (excess) added at -196°C, cylinder allowed to warm slowly to room temp., kept for 3d, cooled to -196°C; fractional condensation;

Reference yield: 50.0%

chlorine (7782-50-5) + mercury(II) oxide (12653-71-3) → hypochlorous anhydride (7791-21-1)

Guidance literature:

In neat (no solvent); 10%Cl2/He flow passed over a bed of HgO kept at about 30°C;
