Any ways to make fire with hydroxylamine hydrochloride?

I'm positive that NaClO2 will react extremely exothermicly with it. I might try it with 100mg amounts when the NaClO2 arrivess

I tried the Si + NaOH reaction tonight, and it definitely works! Mine didn't ignite unfortunately, but it was glowing hot at the end. I'm sure all it's going to take is scaling up a bit more, and possibly using less water.

I used 5.3g powdered silicon (crushed from pure Si chunks, not my thermite-grade material), 15.2g NaOH prills, and about 20mL water. Stoichiometrically only a few mL is required, but it seemed to me that extra water is needed to really get the reaction going. Even after the reaction looked done, adding more water produced a lot more bubbles.

I'm pretty amazed at this reaction. It's not something I would have expected to happen at all.

Awesome! I'm in the process of making some silicon, then I'll give it a try as well. If I can get it to ignite I'll send along a video to NurdRage, you should too MrHomeScientist for some more footage. Try lighting the stream of hydrogen with a lighter.

I may get some Ca(OCl)2 soon. I'll see what I can do with that.

Also my NaClO2 still hasn't arrived. Maybe I'm being impatient since it's only been two weeks since it's shipped, but if those customs folks are the culprit.... :mad:


EDIT:

I've seen a video of pool chlorine and sulfur spontainously igniting
http://www.youtube.com/watch?v=dENDpGR_OAk

I dunno if it's Ca(OCl)2 or TCCA but I suspect the former

I used to mix prilled ammonium nitrate and pool chlorine and it would snap, crackle, pop in a very energetic fashion like popping popcorn only more lively. It never lit on fire but it seemed like it got pretty hot. I stood upwind to avoid potentially hazardous gases. It sort of sounded like lighting a string of firecrackers.
No telling what gases are released so don't risk your health with these mixtures. I hosed down the area thoroughly after the reaction too, to make sure everything was washed away safely.
Back in the 80's I bought a 50 pound bag of NH4NO3 for six dollars. I also took a tour of Air Products and saw a slide show. The fellow told me of an explosion at the plant one time where it threw some pieces of metal a great distance.

I tried mixing my Ca(ClO)2 and sulfur and didn't get a reaction, but that's probably because my Ca(ClO)2 isn't very pure.

EDIT: ill try this again in larger amounts and see if I can reproduce this.

When I was a boy I used to mix calcium hypochlorite and sulfur and light the little piles I set out with a fine spray from a garden hose. Back then it was 75%.

I believe mine is 48%, so I think that's why it didn't work.

Im not sure how easy that would be to completely separate, but probably pretty easy to get it more pure. Ca(OH)2 is only slightly soluble, so you could increase purity by dissolving then filtering. Recrystallization is an option, though I'm not sure about the solubility curve for CaCl2, but I think it would crystallize out as well. Anyway I'm sure purity could be increased, maybe enough to start the sulfur fire.

@NurdRage, any ideas on when your planning on releasing the video? I know were waiting for all the fun that mewrox99 is going to be having with NaClO2 :D but aside from that has the editing process started yet? Are we going to pick a name for the channel? I dont want to seem like I'm rushing things, I understand quality takes quite some time but just wanted to know what the plans are.

I dont think recrystallization would work for Ca(ClO)2, hypochlorites are very unstable in aqueous solutions at high concentrations and would most likely dissociate into chlorate and chloride when recrystallizing. In fact the reason why you can "smell" bleach or solid pool shock is from decomposition of the hypochlorite.

Very true, I just tried dissolving mine and the solution turned green. Maybe some that didn't decompose could be recovered. I only say this because I've heard other people on this forum do it.

@hkparker

I still feel more videos are needed. But if ya think i should start editing it now i'll see what i can do.

No that's fine, let's keep em coming. Just wanted to know what the plans are. This video will be pretty cool if we show a ton of ways.

My KMnO4 didn't do diddly with glycerin. Can't remember how old it is, but at least 25 years. Shouldn't have kept it in a glass jar I guess... :(

You could try adding a small amount of the potassium permanganate to water, if it disssolves completely to form a purple solution it is fine.
Drying the glycerine by heating it to above 100C can be helpful as can freshly grinding the potassium permanganate. You want a lot more permanganate than glycerine as well, it is easy to 'drown' the reaction.

Bah, I can't seem to get this Si + NaOH + H2O reaction to ignite :mad:

This time I used 7.2g Si powder, 23.1gNaOH, and maybe 20mL H2O, and it bubbled and splattered like in my previous post but no ignition. This time I buried the cup in the ground to try to contain the products and heat, but that didn't do me any good.

I don't know how that guy did it in a dixie cup. He must have used a lot more than I did, but I have to grind my silicon manually so I haven't made too much at a time yet. Maybe my Si powder isn't fine enough either.

What is this "accident with sodium chlorite" you speak of on your youtube channel, mewrox? I hope it's nothing serious and that you're not really quitting chemistry? :(

Nothing to serious. Mix self ignited whilst holding it in filter paper. Minor burn on my hand. I've decided that I was impulsive and stupid in making this mixture and took it as my final warning.

I still practice chemistry at school. But hobby chemistry is dangerous and I believe I am above my depth. Myfanwy94 had many signs and warnings of trouble to come. Had he listened he still would have been alive today

I don't wish to talk about this further. I'm actually rather embarrassed about this incident and have only gone into specific detail with my good friends on SM and youtube.

I'm not sure where I warned for the reactivity of NaClO2 recently. I know of mewrox99's order of this chemical and somewhere on the forum I warned about the reactivity of this material. Please be careful with this!

Quote:

...even more so with the ClO2. DON'T MAKE MORE THAN TESTTUBE QUANTITIES OF THIS GAS!!

I have had a few explosions with ClO2, but because only test tubes full of this gas were involved and these tubes were unstoppered no dangerous things happened, but be warned. This gas is notoriously unstable.

I have NaClO2 from the same source as mewrox99, and it is awesome stuff!
