use the same set up but use natrual gas as the carbon source with the sulphur powder but this time use a silica gel catalyst, this drops the temperature by 400oC so will be alot easier to produce, you will have to make use off anti reverse valves if you make it on a large scale because of the gas.
@h0meIandsecurity No... it must be an "oxygen" torch... A regular torch that uses O2 pulled out of air will not get hot enough and just make poisonous gas.
@ihavekankles By day I am a Director of IT.. by night I am Batm... uh... In the evenings company's pay me to do simple research in industrial chemistry. For example I am currently being contracted to design a compound that goes into glaze that can make ceramics "glow in the dark". No glamor.. but still lots of fun.
@coolliger I made it myself....I am not sure I will do a video on it as I think it may be boring... ;) Plus I would have to take the whole thing apart to show how it works... Next time I take it apart to clean and refurbish I will do a video on it.
@yellowmetalcyborg No... the sulfur will boil away before the carbon even gets close to the 900 degrees C to react. One of the problems I have in this experiment is the fact that the tube is too small and gets to hot... melting to much of the sulfur and over powering the carbon (cooling it down). It would be best if the tube was 2X as long to keep the sulfur from heating up.
@myst32YT Ok, thanks I will give this a try. Are there other carbon disulfide production methods that might be more reproducible? This looks like a pain in the neck to do.
Maybe heating hydrogen sulfide gas in the presence of carbon, making the hydrogen sulfide by hydrolysing aluminium sulfide that is made from igniting aluminium powder in the presence of sulfur....
@swerver666 it is a new company that sells small amounts of chemicals/elements and experiments for amateur chemist and home school students. A lot of their products are in my videos...
i needed carbon disulfide for my buckyball video and got really excited when i saw this. once i saw how difficult it is i think ill just buy it instead. great video though
@myst32YT im yet to buy any. im just going to use xylene instead but theres a chemical supplier in missisauga that sells it and just about every other chemical. it's a bit pricey though
Maybe it'd be easier and yield a bit more if some nichrome wire was involved. You could wrap the sulphur end to accurately control the rate and extent to which the sulphur is evaporated.
It'd be excellent if the carbon end could be done with wire as well, but it may struggle to get hot enough if not well insulated.
I haven't checked the numbers, but assume you have enough sulphur and carbon in there for it to produce more, and that it's limited by the tricky heating?
@lexichronicle2 Correct... Very low yield... The nichrome wire is the way to go. That is how they did it on Science madness.... The heating is notoriously difficult for this reaction.
Where does H2S come from? Or more specificaly the hydrogen. The only reactants are S and C and the crucible.

5cc of carbon disulfide is enough for me to make a very interesting and unstable chemical...... tetraSulfur tetranitride.

Nice video!
Wouldn't it be more effective to mix stoichiometric amounts of both chemicals first and then heat the entire tube in a forced air coal fire (>900C)?
What temperature does this need to reach in order to react?
I'm thinking about reproducing this on a much smaller, much more manageable scale with small amounts of chemicals, just to explore the science.
