Hydrochloric acid from cyanuric acid
Have anyone ever tried the chlorination of cyanuric acid ?I am willing to make it in order to synthesis TCCA or HCl,so have anyone ever tried it
before ?i already made some research before you ask i just want to know how it goes from someone who tried it to know things like when to stop and how
much chlorine is needed and does electrolytic Cl2 from NaCl work ?

Yes, it can be made by electrolyzing NaCl solution. I do this on a daily basis. The swimming pool filter pump kicks on. Then the chlorinator kicks on
and CYA is chlorinated. To what degree I don't know.
It works quite well for the swimming pool so it must be do-able in the lab. The fanciest item you might require would be a titanium plate/sheet for
the anode.

TCCA is made by treating a solution or slurry of trisodium cyanurate (saturation is ~0.5M at 20C) with chlorine gas in excess. The product
precipitates (solubility is roughly 0.05M so yield should be about 90%. Using a slurry of trisodium cyanurate will improve this), is collected and
washed to remove residual NaCl.
The product will not work in nonbasic conditions, as TCCA and HCl react readily to form chlorine gas and represent one of the easiest and cleanest
available chlorine gas generating mixtures using cheap and readily available TCCA pool tablets.

the papers I read, said it was two step... see if I can dig that one up...

(a) High chlorinated cyanuric acid yields.
(b) Low chlorine and aqueous alkali losses.
(c) Essentially no by-product formation, e.g. lachryma
tory by-products.
(d) High reaction rates.
(e) Product selectivity, either essentially pure di- or tri
chloroisocyanuric acid or preselected mixtures thereof
can be produced.
pool owner, so I have looked into it. TCCA not always cheap, but quite effective. turns out CYA isn't cheap either
edited, because of faulty memory. thought one step was harder than the other, but it was just two separate steps..
