- After reading this thread and seeing this post, I can keep silent no longer.
- Acetone Peroxide (commonly called Peroxyacetone) is ***extremely*** unstable.
- According to the Handbook of Chemical Demonstrations (the author's name eludes
- me for now - it's designed to provide chemistry instructors with exciting
- chemical demonstrations), Peroxyacetone is nearly as sensitive as NI3. It
- can be set off with flame or an electric charge. It is also highly shock
- sensitive. I have set small (~ .25 g) batches off with flames (candles on
- yardsticks) and the results are quite impressive.
- It is very simple to make, except that the reaction is extremely slow
- unless it's catalyzed. The problem with catalyzation is that not only is the
- synthesis catalyzed, but the decomposition is too. The pure stuff is not just
- terribly foul, but if there is *any* impurity, it can detonate (!) without
- any warning.
-
- (this seems like ample background to get to my point)
-
- Back in my wilder days in high school, I worked with this stuff extensively.
- I had devised a wonderful "fountain" with a paper tube, some cotton and some
- peroxyacetone. I will not get into the details, because I have seen what
- happens when these go wrong. The one I was working with had about .1 g
- of peroxyacetone in it. I was getting it prepared to fire. I set it in the
- (shatterproof) fume hood in my lab and turned around to get my igniter to set
- the fountain off, when it exploded behind me (at about 3 feet range).
- In a nutshell, with .1 gram of the stuff, I was deafened for about 2 hours
- and had it been in my hand, I would not have a hand today. I still have not
- determined what caused the explosion, but there was nothing left of my fountain
- (or the clamp that held it) to start from.
- My chemistry teacher and I concluded that it spontaneously decomposed (as
- it tends to do occasionally).
-
- Ever since this incident, I have not touched the stuff, and will not again
- (even in such small quantities). Peroxyacetone is as unstable as all
- the literature says it is. Be careful with it.
