i have instruction for making potassium chrorate from bleach but there is problem:according to instruction we can use stainless steel but i dont think
this is true.i used stainless steel 316 but ca(clo2) and Naclo destroyed it.
Should you really spoil this forum with such a topic which 1) has already been discussed at length on this forum or in E&W and 2) could find a
better place in "General chemistry" or "Reagents acquisition" ?
As far as I know, chlorates and the like have broader uses than in the only world of energetic materials...chemoleo - 16-6-2008 at 15:01
In this case I'd suggest to use a Teflon-coated pan... what's stopping you?
SS isn't the only option available!
Apart from that, somehow I thought that (but I may be wrong) Ca hypochlorite doesn't disproportionate to C chlorate as readily as NaOCl, but instead,
it decomposes?
Also, is your container clean? Certain transition metals may decompose the NaOCl before it can ever disproportionate...DerAlte - 16-6-2008 at 21:25
Use glass, Hector! And I agree with Chemleo: AFAIK NaClO will produce a higher yield of chlorate than Ca(ClO)2. The last produces oxygen on heating.

I never saw gas bubbles on heating calcium hypochlorite solution to boiling. I certainly smelled chlorine though. It is A Bad Idea. A temperature
below 40C and patience will minimize the chlorine loss. I might try this again sometime, in an enamelled stock pot, using K2CO3 or K2SO4 instead of
KCl as K source, to see if precipitation of the Ca (before heating or not) will give a better isolated yield of KClO3.
