Technology Process of POTASSIUM CHLOROCHROMATE

There total 11 articles about POTASSIUM CHLOROCHROMATE 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:

potassium dichromate + phosphorus trichloride (7719-12-2,52843-90-0) → chromium (VI) oxide + potassium chlorochromate (16037-50-6) + potassium metaphosphate + potassium chloride + trichlorophosphate (10025-87-3,12599-09-6,63736-95-8,39380-77-3)

Guidance literature:

In neat (no solvent); heating PCl3 with K2Cr2O7 in a sealed tube at 166 °C; react. under discoloration;;

Reference yield:

hydrogenchloride (7647-01-0,15364-23-5) + potassium dichromate → potassium chlorochromate (16037-50-6)

Guidance literature:

In hydrogenchloride; boiling K2Cr2O7 in concd. HCl (excess) for a short period of time; crystn. on cooling down;;

Reference yield:

potassium dichromate → chromium (VI) oxide + potassium chlorochromate (16037-50-6)
