jdurg Posted November 16, 2004 Posted November 16, 2004 True. It is fun to make your own elements, but sometimes you have to look at the overall cost of doing so. For Iodine, the cost of making it in the size batch you'd probably need will most likely be higher than the cost of buying a small batch of pure crystals. (Now on a large scale, like they do in the industry, it costs less to make it. But on a small scale like most home users would need, the cost may be a bit higher). Of all my elements, chlorine is probably my personal favorite. That's because I made it myself and did not purchase it from any dealer. I took some calcium hypochlorite and concentrated HCl and generated, cleaned, and dried the chlorine gas myself. It was really neat doing that. While the green color isn't overwhelmingly strong, with a white background to the ampoule and particularly in photographs, it really shows up nicely.
budullewraagh Posted November 16, 2004 Posted November 16, 2004 Sherman Williams. 12 bucks a gal. Pure too. I add it to my gas tank to make 114 oct race gas... eh you cant get an octane number above 100, as octane number signifies the percent of your gasoline that is octane...plus toluene isn't octane...

jdurg Posted November 16, 2004 Posted November 16, 2004 The octane number is actually a rating on the anti-knock properties of the fuel being used. It is a rating based upon the knocking properties of a ratio of isooctane (100) and n-heptane (0). So a gas with a rating of 92 would have the same anti-knock properties as a mixture of 92% isooctane and 8% n-heptane. For octane numbers HIGHER than 100, it's a measurement of how much tetraethyl lead needs to be added to pure isooctane to give it the same anti-knock characteristics. Many cars built prior to 1971 require gasoline with an octane rating higher than 100, as do high performance engines. So if someone has a fuel with an octane rating of 114, then I believe it means that its anti-knock characteristics are the same as a mixture of 100% isooctane and 14 parts (or percent, I can't remember) tetraethyl lead.

r1dermon Posted November 17, 2004 Posted November 17, 2004 IHRA race track, NH raceway, Epping NH, sunoco has a stand where they sell 127octane gas. not many people buy it for their cars because they prefer methanol or some other type of alcohol. more power.. you know? octane is there to prevent your car from knocking or pinging. its what happens when your cylinder fires before the piston reaches top dead center. so it not only robs you power, it really bashes your engine around. and can lead to piston skirt damage, cylinder wall damage, sleeve damage, rod damage, valve damage, exhaust damage, and piston head damage. overall, its not a good thing. in reality, octane makes gasoline harder to ignite, because in high performance cars, where the motor is running significantly hotter, they need a gas that wont ping every time they nail their gas from an idle.

Invader_Gir Posted November 18, 2004 Posted November 18, 2004 Someone said that you could disolve the NI3 in water (i think) before it dries. In this form it can be "painted" onto surfaces. I tried this, but the NI3 would not dissolve in water? What can i use to do this?

r1dermon Posted November 18, 2004 Posted November 18, 2004 invader, there was a book that displayed the process. it doesnt "dissolve" in water, it just doesnt react with friction when its wet. and it can be painted on to surfaces. although this is pretty dangerous. once it dries, you dont want to be NEAR it. one breeze and it goes BANG. no fun.

Gilded Posted November 18, 2004 Posted November 18, 2004 Hmmm... I wonder how much fun painting someone's summer cottage with nitrogen tri-iodide would be.

boris_73 Posted November 18, 2004 Posted November 18, 2004 i have done something like that before i got the idea of Brainiac, i made sure i had a wet paste placed some in some cubboard doors and closed them so when they opend them it went of, great fun, using it on a toilet is quite fun as well

jdurg Posted November 18, 2004 Posted November 18, 2004 When I make big batches, I like to put some sugar in there so it will attract flies and bees as it's drying. It's really fun to see a big nasty hornet get blown to pieces when it gets near the pile.

r1dermon Posted November 19, 2004 Posted November 19, 2004 lol just dont built up a glob too much, because that sucker will go bang at the touch of a feather.

jdurg Posted November 19, 2004 Posted November 19, 2004 It's even more fun when they touch it while it's still wet and get some triiodide attached to themselves. Then as they fly away and it rapidly dries........... KAPOW! lmao.
