Could you use platinum to make sulfur trioxide now that you have made SO2 ?

[@alexandre4953]

Have you tried to use bisulfate with heating to produce SO2 from metabissulfite?

This brings back memories... Or nightmare... When I was a kid I tried making my own concentrated sulphuric acid with the sulfur burning method, a pound of powdered sulphur, melted in a coffee can , being blasted with a propane torch, i didn't have enough copper tubing so used some vinyl, the asperator was held together with tape , not enough vacuum, the vinyl melted , the stand I had the coffee can on collapsed , everything was burning, in an unventilated basement , I barely made it out alive, lucky I didn't burn the house down. I'll never forget struggling to breathe as I collapsed in the backyard with my bronchial tubes nearly completely swollen shut unable to do anything ! Every bit of silver in the house was damaged, some to the point of pitting. When my parents felt it was safe to come back home a week later, first thing my mom did was toss my chemistry set out. I was about 11 , give or take a year... (Tween years)

[@Moritz___]

oh shit just experienced that on a small scale with 14g burning sulfur but quickly reacted, put the can out the window and closed it, quickly got a metal plate from the adjacent room and put the fire out (it was too big to blow out). closed of the room and didnt enter it for 2 days now. i did get one or two good whifs of it but i think im fine sulfur dioxide without a proper setup is no joke

[@HyperHyena88]

Damn son 😂 . . . . We all do dumb things, I once used a firecracker to get our family dog out of the bathroom, except I chose to put the firecracker in the toilet and it blew the underside of the john out. The dog was even more reluctant to come out of the shower after that 😂 I was around the same age, yours is more impressive though from a smart kid perspective, at least you were doing something productive, I was just trying to get the dog out of the bathroom to take a shit alone 😂.

@@HyperHyena88 well my ultimate goal was to create a nitration mix, and make my own nitroglycerin ... ...Things could have been worse... I did make NI3 (touch powder) , but the little crystals exploded like small firecrackers just from starting to dry so I panicked and washed it down the drain... For the next day pipes were rattling, you can hear things popping in the sewers... Didn't tell my parents what those noises were coming from, they thought it was something from the town...

Have you considered looking into the DMS/DMSO process and the different ways SO2 can be produced from organosulfurs and reacted with them (IE via methylation/hydrogenation/oxidation) to form other useful compounds? Reading into it recently myself I find it an interesting set of ways to use these waste products to produce more useful compounds.

organic sulfur compounds are one of a hell to work with, so I wouldn't use them to make just SO2

Great video Nurdrage! Thanks, in our smelting process, they're using diesel to cook the concentrates, this is producing a nox gas in the sulphuric acid. Could you some how explain how a company who treats a sulphuric acid which contains nox? This gas is produced when we dilute the acid, which I do when regenerating a Cation unit (part of the process to make demin water to recharge the resins) I know nox is pretty bad, we do have gas monitors for it as we can't smell it. Thanks again for your videos.

[@JustAnotherAlchemist]

I'm interested in methods of turning calcium sulfate minerals (Gypsum, plaster of paris, etc.) into sulfuric acid via evolution of sulfur dioxide. I've become interested in this for SHtF/survivalist scenarios; sulfate minerals are incredibly common the world over, where as elemental sulfur is comparably rare. My understanding is that merely mixing such feed stock with high silica minerals (shale, mud stone) and getting it hot enough achieves the goal. I'd be interested in a NurdRage take on the process.

[@mabs9503]

Cool gonna follow this tutorial and leave the URL to this video on a note nearby just in case.

[@experimental_chemistry]

Here in Germany sodium bisulfite and hydrochloric acid are very easy and cheap to obtain (6 Euros for a litre of technical grade HCl from the hardwarestore and 11 Euros for a kilogram of bisulfite online). The only problem is the storage: both substances need to be stored in bottles under tightly sealing teflon-coated caps, otherwise the escaping gases will corrode everything made of metal and located in the same room. The use of conc. sulfuric acid is completely forbidden for private individuals in the EU.

[@arjayUU]

Yay, making cautious stuff again!

[@lrmackmcbride7498]

Metabisulfite method for small quantities of high purity. Burning method for large quantities. A pair of good videos would be making the vanadium catalyst and then making sulfur trioxide. Key step is purifying the burning sulfur dioxide to remove water and sulfur and sulfuric acid which damage the catalyst. Making sulfuric acid from sulfur trioxide is also non-trivial. The first of two methods I have tried are dissolving in concentrated sulfuric acid to make fuming acid then diluting. The second is putting the sulfur trioxide in a closed setup with an appropriate amount of water in two cups. Everything gets coated with sulfuric acid, but you get 98% acid where you had sulfur trioxide. The cheapest way to set this up is a flask with a vacuum adapter and stopper. Use ptfe tubing to attach the two pairs. Since it takes a long time dedicated glassware is ideal. Some gas line tubing has ptfe core which is available at auto parts stores for reasonsble prices. If you have a distillation set up without a condensor you can use that. It takes a bit but it works and everything is contained. But it will be out of use while this is happening.

[@joshrempel2076]

Pretty sure you can substitute with Potassium Metabisulfate, getting potassium chloride as your bi-product instead. I find K2S2O5 is easier to find than Na2S2O5. Potassium Metabisulfate is sold as a beer additive at Canadian Superstores. Muriatic acid at Home Hardware.

[@tokajileo5928]

2H2S+SO2=2H2O+3S. in gas phase it is nice reaction one can see formation of yellow sulphur 'smoke'. I wonder what happens when you mix liquid SO2 and liquid H2S .

[@SafetyLucas]

Won't the hot SO2 erode the copper tubing into copper sulfate? Especially if there is atmospheric oxygen available?

[@theterribleanimator1793]

it shouldnt, SO2 doesnt readily react with copper, neither does H2SO4, if it does at all it will probably passivate.

[@dimaminiailo3723]

Wood charcoal can be used instead of sulfur, it's more convenient being non-volatile. SO2 is somewhat contaminated with CO and CO2, but for most purposes it's not a drastic difference

[@PhillipChalabi]

NerdRage posts a video, I click simple as that.

[@seanb3516]

I would like to add Smelting of Gold Concentrates Containing Sulphides (as in almost all gold concentrates). If you have ever done Roasting you know there are clouds of SO2 gas that stream off for about 30 minutes. Pass those fumes through a simple water spray box and you'll make dilute H2SO4. Boil the acid until it becomes syrupy and enjoy the spatter wounds on your face. Fun! :D

[@user-py9cy1sy9u]

SO2 + H2O makes H2SO3 not H2SO4

[@pacman56781]

You still need V2O5 to catalyze the SO2 to SO3

[@ralfvk.4571]

It should be possible to use the Sulfur-burning method also without vacuumpump, if the S is burnt inside a closed container, into that just enough air is pumped carefully, so the flame does not go out.

Can someone explain to me the method of sulfuric acid to produce sulfur dioxide? I don't know English (I use a translator).

Is the comproportionation S + 2 SO3 -> 3SO2 viable/easy? If yes, then for some SO2-reduction reactions it may be viable to set up SO2 regeneration loop, where you use SO2 + yourstuff -> yourstuffreduced + SO3 in your main reactor and regen SO3 back to SO2 in auxiliary regen reactor

[@dimaminiailo3723]

SO2 is an efficient reducing agent in water solution, not by itself, so you product will be sulfuric acid. anyway, SO2 is very cheap for most people and thus that method is not very convenient

[@bpark10001]

What about putting the sulfur candle in sealed chamber & feeding in oxygen from oxygen concentrator? Will the reaction get violent? Can the rate be controlled by the oxygen feed rate?

[@NurdRage]

It would work just fine. The issue is that making one tends to be a little more complicated than the vacuum method because you have to make it air tight and capable of withstanding the high temperature of burning sulfur. It can be done, but a vacuum based system doesn't need good sealing, in fact it can be very leaky and still work.

[@bpark10001]

My question focuses on the use of pure O2 versus air. You could still use vacuum, but flood by leaky means O2 around the funnel. Will the reaction become violent or explode, sending molten sulfur everywhere? The object is to reduce the amount of gas delivered for a given amount of SO2, because for most gas deliveries like this, most of it doesn't get absorbed in the target flask & spews about, wasting product & polluting the environment. If ALL the gas was SO2, then there would be little need for venting the reaction vessel, so SO2 could be regulated for "no output" from the vent. Neighbor's silverware would remain untarnished.

[@NurdRage]

If you're going to go through the trouble of making pure o2 and a sealed container then you may be better off using the sulfuric acid or metabisulfite methods. Less work for pure SO2

[@bpark10001]

r @NurdRage I already have the concentrator. I don't have sulfuric acid. What I want to know is if pure oxygen will make sulfur candle dangerous.

[@5467nick]

@@bpark10001Concentrated oxygen and combustion is always dangerous. Any combustion reaction will get more violent when you increase the concentration of the oxidizer. Rate control would probably be difficult. If you can't guarantee that all of the oxygen you add will first react with the sulfur, then increasing the flow at times might increase the reaction rate, or it might just mean the oxygen you add will pass through into the exhaust with the SO2. It's probably not impossible, but that's not an experiment I'd want done anywhere near me. If your concern is about waste SO2 escaping and harming metal objects, maybe you could make a scrubber where you bubble the exhaust from the vacuum pump through some sodium hydroxide dissolved in water or something similar. On the plus side, this would make sodium metabisulfite, which you could use to generate SO2 gas on demand in a more controlled manner.
