KCLO4(Potassium Perchlorate)

Sodium Chloride is electrolysized to render Sodium Perchlorate in a single run. A rewound "MOT" is used with a pi filter for the power supply. Power supply quality is checked under load with an oscilliscope. DC ripple is less than 1/10 volt. The electrolysis voltage is kept above 6 volts and the current is maintained at 25 amps. Total run time was 180 hours. Solution temp was 85-90C.

Electrolyte consisted of 1140g of sodium chloride (table salt) dissolved in 4L of distilled water. All of the electrolyte was run through the 3L cell over the course of 7 1/2 days.

At 144hours run time, a test for perchlorate was done using Methylene blue. A strong presence of perchlorate was indicated by violet color. The cell run continued for an additional 36 hours.

The electrolyte was hot filtered to remove the white flock that accumulated on the bottom of the cell and then boiled in a beaker for 45 minutes. The 3L solution was divided in half. 1500mL of electrolyte and a boiling 2 liter solution containing 2 lbs. of KCL were combined in a 5 liter beaker. This metathesis mixture was left to cool to room temp and then cooled in a refrigerator. The accumulated crystals were filtered and thoroughly washed with distilled water. The yield was approximately 980g. Another test with methylene blue on the result strongly indicated perchlorate.

ok so I had a question for ya.. here goes. I liked your ion replacement method to ppt. out the KClO4, and it got me thinking of some other salts. then I realized I had bought a cheap bag of sodium nitrite a while back. can the NaNO2 be worked up in the same manner to NaNO3? or does this only work with oxychlorides? that would be nice if it worked and was quick. like the -ClO3 ---> -ClO4 conversion. maybe take a stab at that. I still need electrodes :(

@demnlordd666 I don't think that it will work in place of the Na and K salts.

[demnlordd666]

@ytmachx ya I guess I worded that odd. but I just meant that thinking about other salts reminded me I owned NaNO2 already, and I was wondering If I could get it to oxidize to NaNO3 by electrolysis. not in any way talking about perchlorates or an ion replacement, sorry

@ytmachx i know that it bleach in a few minutes , the colors i told u i got were just after dropping methylene ok then , why did it ignite with h2so4 after drying the crystals and mix with dextrin (does PH play any rule before drying the crystals?)

[ytmachx]

@Real0Nighto The difference is deep blue or violet. The electrolyte solution will bleach out the color of the blue or violet color of the methylene blue in a few minutes, so check quickly. You must correct the pH after treating with HCI. You should be 7-8 when you test.

@ytmachx sorry i meant bluish violet not magenta

[Real0Nighto]

@ytmachx i gave it a try this morning , methylene blue turns totally purple like yours , when i treat with hcl , boil , test , no purple just blue , when i neutralize with naoh i get magenta , but it turns blue again by adding kcl

i recrystallize kclo4 and test , i get blue as no perchlorate exist , by drying the crystals , mixing with dextrin , it ignites fast by h2so4 , i donno what the hell is goin on , first perchlorate next chlorate , i think hcl turns clo4 into clo3 XD

[Real0Nighto]

@ytmachx hmmmm i forgot asking what will happen if excess hcl is added will it affect perchlorate (i will recrystallize nh3clo4 and wash it, is this enough to eliminate remaining hcl)

i just wanna know enough about what im doing for i dont wanna damage anything lol

[Real0Nighto]

@ytmachx i can take care when evaporating clo2 like performing outside with wind blown from my back

but if i used hcl will it eliminate all chlorates from the solution to be used in ammonium double replacement reaction to convert naclo4 to nh3clo4

last answer please i need ammonium perchlorate its urgent lol

and there is another question i searched everywhere but i didnt find answer

will perchlorate decomposes if electrolyzed more

i appreciate your longanimity -_-

@Real0Nighto If you will recall, in the "Potassium Chlorate Electrolysis" video, where I used KCL, the KCIO3 falls out of solution because of its relative insolubility, preventing further electrolysis. Therefore, if you intend an electrolysis of KCIO4 from salt, you must start with NaCl. Chlorate can be destroyed by lowering the pH to about 1or 2 with HCI and then boiling off the chlorine dioxide, but his is dangerous and should not be attempted.
