Oct 22, 2023 · I’m not sure you can go from ammonium perchlorate to potassium perchlorate by salt metathesis. Try it out, e.g. by mixing with KCl. Potassium perchlorate is almost insoluble at low temperatures, so it should be easy to isolate, provided the reaction works in the first place.

Mar 25, 2022 · He solved it by treating the perchlorate (under water or electrolyte, I don't recall which) with potassium metabisulfite solution*, which produced sulfur dioxide that destroyed the chlorate contamination, leaving the perchlorate chlorate-free.

May 14, 2014 · The potassium chlorate produced can also be thermally decomposed to perchlorate and chloride, so it's possible to get all the way to perch without using electrolysis. The synthesis is pretty straightforward and the equipment and starting chemicals cheap.

Jun 12, 2019 · This would be best done from sodium chloride/chlorate as a starting material by the way, as the potassium chlorate and perchlorate only have 1/100th the solubility.

Jan 5, 2022 · If you want KClO4, you need to do an electrolysis of NaCl, first to NaClO3 with MMO electrodes and then to NaClO4 with PbO2 electrodes. Then you can mix a solution of NaClO4 with KCl to get KClO4.

The molten potassium chlorate decomposes liberating oxygen, also an endothermic process. 2K+ClO 3 - + energy → 2KCl + 3O 2 (g) This process actually takes place in two steps: 1) the formation of potassium perchlorate, followed by 2) the …

Jan 3, 2008 · Is there a way to make Potassium perchlorate from Potassium chlorate, or would it be easier to make it from mixing solutions of Sodium perchlorate and Potassium chloride? Also, the latter causes the formation not only of Potassium perchlorate but also Sodium chloride.

The Potassium Perchlorate is not very soluble and will ppt out immediately as a very fine crystalline product (your solution will look like yogurt if you add the KCl quickly) as soon as you add the KCl to the Sodium Perchlorate.

Dec 9, 2013 · Potassium perchlorate is not nearly as reactive as potassium chlorate. Ignition with a drop of H2SO4 usually does not work with perchlorate. You really need to light the mix and even that is not trivial in some cases (e.g.

A graphite anode‐steel cathode cell is used for the conversion of chloride to chlorate, and a platinum‐clad anode‐steel cathode cell is used to change chlorate to perchlorate. Construction and operating data are presented for both cells.
