This forum has been very helpful and intresting, thanks to all. I do have another question. I have been able to make potassium chlorate from bleach and potassium chloride, I was wondering what the procedure is to make Potassium Perchlorate? If possible what the proper weights for the chemicals and solutions are. Thanks Again!

[Gilded]

I'd imagine heating the chlorate a bit (not too much, or it will decompose in to potassium chloride) would make it perchlorate. About 200 C / 400 F, perhaps?

[budullewraagh]

woah woah. how do you oxidize hypochlorites to chlorates using chlorides?????

[YT2095]

simple answer... You CAN`T

[budullewraagh]

yeah thats what i thought:\

[Gilded]

"woah woah. how do you oxidize hypochlorites to chlorates using chlorides?????"

 

What? I didn't say anything about USING chlorides. I just said it can decompose into NaCl if heated too much, which is unwanted.

 

Edit: Or did you mean the bleach-NaCl -> NaClO3? I think I'm tired.

[budullewraagh]

yeah thats what i was referring to

[JerryK]

Take one gallon of bleach, place it in the container, and begin

heating it. While this solution heats, weigh out 63 grams of

potassium chloride and add this to the bleach being heated.

Constantly check the solution being heated with the hydrometer,

and boil until you get a reading of 1.3. If using a battery

hydrometer, boil until you read a FULL charge.

 

Take the solution and allow it to cool in a refrigerator until it

is between room temperature and 0 degrees Celcius. Filter out the

crystals that have formed and save them. Boil this solution again

and cool as before. Filter and save the crystals.

 

Take the crystals that have been saved, and mix them with

distilled water in the following proportions: 56 grams per 100

milliliters distilled water. Heat this solution until it boils

and allow to cool. Filter the solution and save the crystals that

form upon cooling. This process of purification is called

"fractional crystalization". These crystals should be relatively

pure potassium chlorate.

Is this not correct??

[RICHARDBATTY]

What do you want potassium perchlorate for.

[budullewraagh]

Is this not correct??

sorry man but all you have is a mixture of sodium and calcium hypochlorite and potassium chloride.

[budullewraagh]

What do you want potassium perchlorate for.

it's a good oxidizer

[budullewraagh]

on second thought, there may be a double replacement reaction. unfortunately i have yet to find an activity series of monatomic AND polyatomic anions

[JerryK]

The crystals that come of this mixture look like diamonds. Here is what I did after the crystals were dried:

2 parts Potassium Chlorate (The dried crystals)

1 part Sulfur

1 part Al

 

Just putting a spec of this stuff on a hard surface and hitting it lightly with a hammer made a BIG BLAST! (So what is this stuff if its not Potassium Chlorate?)

 

What I was wondering if there is a way to make potassium perchlorate - to make a more stable flash powder.

it`s a long winded method, but it does work, I`ve done the same myself in the past, until I found an easier way

you should not add sulphur to any chlorates it makes the mixture unstable

[Gilded]

"it`s a long winded method, but it does work, I`ve done the same myself in the past, until I found an easier way :)"

 

Perhaps you would like to share the easier method?

[boris_73]

there is an easier method buy it 500g for £7.00

 

Edit: £5.90 from http://www.labpakchemicals.co.uk

[Gilded]

"there is an easier method buy it 500g for £7.00"

 

[nitpicking]OR you could buy 500g for £5.90 at Labpak Chemicals![/nitpicking]

 

Anyway, making stuff is more fun than buying stuff. Unless it's the "make one mistake and die" type of making process.

[boris_73]

yes i do enjoy making my own chemicals but when the cost making it out weigh the costs buying it ill just buy it

[YT2095]

make it 1`st regardless of the cost, just for the experience, after that whatever`s cheapest

 

that`s how I like to do it.

[boris_73]

what is your easier method then YT because i would like to make some for the experience

[YT2095]

there`s a multitude of ways (almost as many as there are compounds containing K and N and O).

 

if I don`t buy the stuff as it is, try NaNO3 and KCL or potassium sulphate from the same gardening shop ya bought the sodium nitrate from

 

the REAL hard way, is get a Huge bucket, put in old BBQ ashes and and even cig ash, add some pee pees and horse crap (manure), leave it outdoors over winter (I do).

then dry the liquid in a shallow tray in the sunshine, collect the crystals.

 

keep doing that till all the liquids used up (I make mine in a plastic barrel 4 foot high and 2 foot diameter) and you have a bag of crystals.

it`s all just a case of purifying them after

[boris_73]

oh yes that has just reminded my dont buy potassium nitrate from http://www.gardenchemicals.co.uk i payed £9.50 for 500g plus postage so about £12 for 500g of potassium nitrate instead get it of http://www.labpakchemicals.co.uk for about £3 for 500g that way you can get 3 times as much you have to include postage thats why it's not four times as much, Anyway YT how well does the bleach method work IE how much crystals will you get and how easy is the NaNO3 and KCL method i am guessing you get a bit more then the amount of NaNO3 you use

[YT2095]

Bleach!???? for KNO3?

 

you`ve lost me there!

 

for a start NEVER mix nitrates and chlorates!

[Gilded]

That bleach thing was about KClO3, I think. Even though this seems to be the KNO3 thread. Weird.
