Interesting substances from SO2...
Hallo to all,
after some cough, I and SO2 have becomed friend!
What can I prepare with this gas?
Thanx all for help!

Early in my career I had a job in the technical service department of a paper pulp mill. For the "sulfite" cooking liquor the operators
would make SO2 by burning sulfur. We (tech staff) would have to periodically go down to the burner room to run an Orsat analysis (must have been for
O2 content of the exit gas). It would nearly gag us around the burner. But the operators did not complain - in fact they said it increased their
sexual potency! (I'm not recommending this.)
The SO2 was mixed with lime water to form Ca(HSO3)2 for the liquor. This was done by running the gas countercurrent to the lime water in an
absorbtion column. The column packing was small wood logs about 12" (30cm) long. This always made me laugh just thinking about it as I was
fresh out of school where we of course only talked of Raschig rings and Intalox saddles.
The single most important condition for a successful synthesis is good mixing - Nicodem

It all boils, or burns, down to saving a dollar. DOW chemicals got started making Bromine from brines using tarred wood to make the Chlorine
electrolysis cells. Even then they thought it was ugly, but it held up well. In essence,it's the ideal of amateur science too. Expensive
equipment and supplies allows us to do things in a predictable, repeatable way, without reinventing the wheel every time we must distill water, do a
titration, or weigh out a chemical.

From SO2 you can make sulfury chloride SO2Cl2.
Though you need a lot of glassware to assemble the apparatus to do that.
SO2 and Cl2 must be generated simultaneously in equal volume streams and must both be dried with H2SO4.
SO2 for this purpose must be made from sodium metabisulfite + an acid, burning of sulfur can never be used for this purpose because the SO2 is way too
impure.
Dry SO2 and Cl2 must then be mixed and the mix fed into the top of a liebig cooler filled with active charcoal as the catalyst.
Water has to run through the cooler in order to dissipate the heat of reaction.
If done right, SO2Cl2 will drip out of the low end of the condenser.
There is also the camphor method where SO2 and Cl2 are bubbled sperately one after the other into camphor, when enough SO2Cl2 has formed they can be
added simultaneously.
The SO2Cl2 has to be distilled from the camphor after this.
SO2Cl2 is very useful, in combination with a radical initiator like dibenzoyl peroxide (I think that acetone peroxide can be used too) it can, via a
radical reaction mechanism, chlorinate toluene to benzal chloride without risk of overchlorination (benzotrichloride can't be formed here) and
without any ringchlorination.
By refluxing with an excess of methanol, dimethyl sulphate could possibly be prepared.
By refluxing with an exactly calculated amount of water, chlorosulfonic acid can be prepared.

Low level SO2 would probably affect the body like a persistant lung infection, it would not become immune but it might stop retaliating. Increased
sex drive is probably due to the body unconsciously thinking its in danger of dying soon.

TO ALL WHO'VE TALKED ABOUT ILLNESS:
Getting ill isn't an interesting thing to do with SO2!
If I can get an setup for SO2Cl2, I will first try SCl2!
Any idea about SO2 derived compounds welcomed!

I'm not suggesting you would make yourself ill on purpose. Interesting doesn't come into it.

Saturating a KOH solution with SO2 and then reacting with KNO2 gives N(SO3K)3. It is something I have been wanting to try for a while. Decomposes
within a month though.
I wonder if N(SO3K)3 could be nitrated to N(NO2)3 by replacing the SO3K groups with NO2 in an analogous way to how HNIW can be made from that
condensation product of glyoxal and K-sulphamate? N(NO2)3 could be rather interesting if it exists, but I digress...

SO2 forms a complex with iodide. That is a very interesting reaction. Just add some potassium iodide or sodium iodide to a solution of SO2 in water or
to an acidified solution of a sulfite. This complex is said to have formula [I.nSO2](-), with n being 1, 2, 3 or 4. It is intensely colored
yellow.
When you have the possibility to liquify SO2, then you can dissolve KI in SO2 and extract the solid complex, but that unfurtunately is out of reach
for me .

Hi,
thanks all for interesting suggestions!
If instead of KOH one uses NaOH, would the product be also nitrable?
