Legality of Organic Peroxides in Canada

[Needtoknow]

I plan to use Acetone Peroxide in my potato cannon (legal as it does not exceed 493fps) because it deflagerates. But it can also be used as a explosive if its packed. And explosives are illegal to manufacture and use.

On the main page of http://laws.justice.gc.ca/
Quote:
As of June 1, 2009, all consolidated Acts and regulations are "official", meaning that they can be used for evidentiary purposes.
And under the definition for explosive under the Explosives Act ( R.S., 1985, c. E-17 )http://laws.justice.gc.ca/en/showdoc...0090623?page=5:


"explosive" means any thing that is made, manufactured or used to produce an explosion or a detonation or pyrotechnic effect, and includes any thing prescribed to be an explosive by the regulations, but does not include gases, organic peroxides or any thing prescribed not to be an explosive by the regulations;

Since Acetone Peroxide is an organic peroxide it is very legal.



But over here in the gazette it says:


1. (1) The definitions “explosive” and “process vehicle” in section 2 of the Explosives Regulations (see footnote 1) are repealed.

And:


“explosive substance” means a solid or liquid substance — or a mixture of solid and liquid substances — that is capable by chemical reaction of producing a gas at a temperature, pressure and speed that could cause damage to the surrounding structures and infrastructure and includes a pyrotechnic substance even if the pyrotechnic substance does not produce a gas; (matière explosive)

Which would make it illegal.


That was there April 23, 2009.
So which one is valid because this is really confusing me and I don't want to do something illegal because the most recent one is a flaw. Thank you for your time :-)

moving to backyard ballistics, see if they can answer your questions about AP.

Let me stop you right there...

I don't care if it's legal or not, it is straight up retarded to use AP. But you can make BP which is very legal and won't turn your cannon into shrapnel which will probably destroy your face.

IBM got it. Mostly.

AP doesn't need to be packed for it to det. In a cannon... ie confinement... as soon as it is ignited... all of the AP will burn up in a fraction of a second (it has its own oxygen, so particle size is not as relevant) producing some gas and much less heat than common spud gun fuels. FUELS. The word FUEL is key. AP has a crappy fuel value. If you heat air, it expands. Since less heat... less expansion. Less over all thrust. However... the volume of gases that are produced... will be produced VERY fast. It will be a shock to the combustion chamber and could probably damage it. With cannons... and things with heavy projectiles and long barrels... you want a more gradual build up of gasses... not instantly.

You might want to go and read some books on the history of cannons and see the lessons they learned about the propellant grain size vs. the likelihood of the cannon blowing up.

I wouldn't recommend BP. You have to know which grain size is best for your application... PVC splinters into shrapnel regardless if ruptured... spuds are wet, wetness and BP don't mix well... spuds fit tightly in the barrel... BP favors not blowing up the cannon/mortar when the projectile is a loose fit.

Compare the heat and volume of gases produced from 1 mol of AP vs 1 mol of various hydrocarbons.

Just use metered propane or something like all the other big time spud guys are doing. They have tested everything for you already. Forget about solid propellants.

When they mean organic peroxide... they are probably referring to methyl ethyl ketone peroxide (in water solution) or benzoyl peroxide (various uses i can't remember) to be used as a catalyst to cure fiberglass resins... When they are talking about gases... they probably didn't want to class them as explosives... because it would be a damn pain for welders to have to get explosive permits to buy, transport, use, and store welding gases... AND make a storage magazine...

AP can DDT (deflagration to detonation), unconfined, in amounts of only a few grams. If you are really itching to use a HE-type propellant, look into nitrocellulose. That's what the military uses as a propellant. BB is not so much concerned about the legality of our practices, but the safety. Also, as the above posters mentioned, any sort of solid fuel is BAD at launching tight-fitting projectiles. Your cannon tends to blow up.

organic peroxides will not work well as propellents
they typically explode if confined, and it is the type of the explosion which will shatter the tube and create scrapnel without even accelerating your potato very much

gas explosions work much better for potato guns
