Ozone solubilities - Chlorocarbons

Finnnicus - 6-7-2013 at 04:08

The only reference I could find for this is the wiki page which states:

"Ozone is a pale blue gas, slightly soluble in water and much more soluble in inert non-polar solvents such as carbon tetrachloride or fluorocarbons, where it forms a blue solution."

Does this have any truth to it? Any one have any references? Anybody with an O₃ generator willing to try it?

Also, would an ozone solution be an oxidizing agent similar to hydrogen peroxide?

What I've read, ozone should be soluble in tetrachloride and sulfuric acid, but the solubilities are still rather limited, speaking of few grams per liter maximum. Yes, it can be used as an oxidant, and according to my info, it will generate NH4NO3 from NH3(+H2O?), make SO3 of SO2, create lead oxide in situ and corrode several materials.

Im planning on building electrolytic ozone cell, similar to chlor-alkali, but using only pure water with 0.5-1% NaOH as electrolyte: it should generate up to 30% O3 with O2 at cathode and H2 from anode.

Physical properties<hr /><a href="http://en.wikipedia.org/wiki/Ozone" target="_blank">Ozone</a> <img src="../scipics/_wiki.png" /> is a pale blue gas, slightly soluble in water and much more soluble in inert non-polar solvents such as <a href="http://en.wikipedia.org/wiki/Carbon_tetrachloride" target="_blank">carbon tetrachloride</a> <img src="../scipics/_wiki.png" /> or fluorocarbons, where it forms a blue solution. At 161 K (−112 °C; −170 °F), it condenses to form a dark blue liquid. It is dangerous to allow this liquid to warm to its boiling point, because both concentrated gaseous ozone and liquid ozone can detonate. At temperatures below 80 K (−193.2 °C; −315.7 °F), it forms a violet-black solid.[8]

some solubility data for O3 and O2
http://www.nist.gov/data/PDFfiles/jpcrd219.pdf

ozone in water

some more from google

this one is worth requesting I think

From what I have read, ozone is soluble in carbon tetrachloride.

I am not really sure how compatible/stable this solvent is. Let's not forget ozone can oxidize chlorine dioxide, although this probably much due to ClO2 being a radical molecule to begin with.

In fact, I think ozone is several times more soluble in CCl4 than water.

similar effect to dissolving O2 in perfluorocarbons
Oxycyte (perflourinated-tert-butylcyclohexane) is used as a blood substitute for carrying O2
the reason O2 is so soluble in it is because the intermolecular forces in the liquid are so weak

However, possibly unsafe to dissolve O3 in perfluorocarbons (other than CF4), it could potentially lead to explosive mixtures. (not sure about this though)

How do you generate O3 instead of O2 at cathode?

On topic, I don't think it would be a good idea to mix strong oxidizer with chlorinated solvents, we are stabilizing them with ethanol all the time so it doesn't form phosgene on reaction with air let alone ozone.

Ozone is, in fact, blue

I am taking no credit for this, but Kristof has a picture on his blog of ozone in liquid nitrogen.

Ozone

Also, there's a picture of his arm showing the dangers of ozone

(I am shamelessly promoting your blog today, I should get a bonus Kristof.

Also, your silver macro image is now my computers wallpaper!)
