YT2095 Posted March 3, 2006 Share Posted March 3, 2006 I`ve been given nearly a gallon (5 litres) of Toluene today, I`ve also contributed Much to this site in the past, so I figure I`m about due to ask a few "lame" questions myself does anyone know of any interesting things I can do with this stuff? and no, before any K3wl says it, I did the TNT thing over 20 years ago and have no interest in that anymore, I was satisfied. I`de like to try making the benzoic acid with acidulated KMnO4, ok I already Have this acid, but I`ve never made it this way before. also Sulphonic acid synths to make detergents, I`de like to try that too. and any Other ideas or synths for a relative Orgo Newb seems a pity to use all of it over a lifetime as a simple de-greaser suggestions...?

RyanJ Posted March 3, 2006 Share Posted March 3, 2006 What can you do? 2,4,6-trinitromethylbenzene is fun ut you've done that... Make some Phenol... If you can then you can make some Picric acid... No idea at all... research leads this though: Inhalation of toluene fumes can be intoxicating, but in larger doses nausea-inducing. Chronic or frequent inhalation of toluene over long time periods leads to irreversible brain damage. So be careful Cheers, Ryan Jones Link to comment Share on other sites More sharing options...
woelen Posted March 3, 2006 Share Posted March 3, 2006 Toluene can be used to make beautiful crystals of sulphur. You can also purify sulphur with it easily. http://woelen.scheikunde.net/science/chem/exps/S+toluene/index.html Try to scale up this experiment and see if you can make beautiful crystals of sulphur.

WOW those are pretty...

YT2095 Posted March 3, 2006 Author Share Posted March 3, 2006 Toluene can be used to make beautiful crystals of sulphur. EwWwWwwww Nice! I`ve got to try that, fantastic idea! as for Picric acid and associated metal picrates, I`ve done that too at about the same time as the TNT (and others), it`s just Boring now and would be a waste of good chemical(s). I want to make thing`s I`ve never made before and watch how it happens and works. edit: Woelen, after a good read, I wondered why you disposed of the toluene soln afterwards? surely allowing it to go to Evaporation would have done a similar job as lowering the temp in a freezer? just a thought Link to comment Share on other sites More sharing options...
raivo Posted March 3, 2006 Share Posted March 3, 2006 I have done benzoic acid by potassium peramaganate oxidation of toluene. If i recall correctly i refluxed solution of potassium permanganate for 4 hours with small quantity of toluene. After filtering and evaporating got white powder with almost no smell but dust was very irritating. It made me cough if prespired even in smallest quantities. I assumed that this is benzoic acid. I used it to make esters. It can also be used to make benzene by dry distillation. Toluene can be chlorinated to make benzyl chloride which is quite remarkable intermediate in organic synthesis. Edit: Just remembered some more details... After filtering and evaporating most of water i added some HCl. Benzoic acid precipitated. Precipitate was collected by filtration and dryed to get that white powder which i used to make esters. Link to comment Share on other sites More sharing options...
YT2095 Posted March 3, 2006 Author Share Posted March 3, 2006 well having just moved into a new house and having most of my kit still in boxes, I can`t do any Chlorination just yet, but I`ll have a try later one. I want to make such things as these in bulk so that I can use them later as further "Stepping-stones" for other synths. I really would like to try this Sulphonic acid addition to make a working detergent also, I don`t exactly know How the proc is done yet, but it`ll nice to get some product from it that works also, does anyone know what amount per litre of unleaded fuel, I need to add to make 4 star petrol? this could save me £100`s alone! (nearly £6.00 for 125ml of the Octane additive!). Link to comment Share on other sites More sharing options...

If you let all of it evaporate, then all soluble impurities of the sulphur also will be in your crystals again. So, when you use this for making pure sulphur, then you should not let all of it evaporate. Link to comment Share on other sites More sharing options...

jdurg Posted March 4, 2006 Share Posted March 4, 2006 Heh. I actually like the smell of toluene. It is a major component in plastic model cements, so whenever I smell it I get reminded of all the time in my youth I spent building model cars.

YT2095 Posted March 4, 2006 Author Share Posted March 4, 2006 it reminds me of marker pens, in fact I had to forcibly take the bottle back off my wife while there was still some left in the bottle! Woelen, yeah, I thought about it afterwards, removing some of it would be best in case there are soluble materials in there. Link to comment Share on other sites More sharing options...

Darkblade48 Posted March 11, 2006 Share Posted March 11, 2006 Doesn't It Make Trinitrotoluene? Most likely not. I believe normal nitrating conditions (of course, you'll need another reagent, not just HNO3 to nitrate the ring) will only give you a maximum of two NO2 groups on the ring.

YT2095 Posted March 11, 2006 Author Share Posted March 11, 2006 TNT synths (other than being Against what I originaly posted!) are 3 stage, agreed "Simple" but it also takes Time to do it properly, and it`s nowhere NEAR as dangerous as it`s being made out to be! now then, can we get this Topic BACK on track again!

You can also purify sulphur with it easily. http://woelen.scheikunde.net/science/chem/exps/S+toluene/index.html Try to scale up this experiment and see if you can make beautiful crystals of sulphur. Interesting note, I`ve tried the above and noticed something Very Strange/unexpected! I put in 30 grams of inpure sulpher powder into a 250ml erlinmyer flask and then topped the rest of the space up to the 200ml mark with toluene. I put this in a high walled metal container over the heating element (I didn`t want anything to crack and leak and catch fire) I also did this in a shed with everything open so as not to be overcome with fumes, happily there were non of any significance, but it was handy to have the area to throw the lot out IF it caught fire. Anyway, about 2 mins before boiling point was met, the volume in the flask increased to the 225/230 ml mark!? I was quite astonished at this expansion, granted all liquids will expand a little upon heating, but this was quite marked! did you notice anything similar in your trials? and as for crystals, no, I`ve not managed huge ones yet, I`m still getting all the garbage out the garden sulpher, I`de say a good 80% of the crap has gone already just using this process, when I get a good purity of sulpher, Then I`ll try for a Huge one, I think I`ll cheat and keep the best of my smaller ones as a seed to get it started with Link to comment Share on other sites More sharing options...
woelen Posted March 21, 2006 Share Posted March 21, 2006 That is indeed impressive, such a large expansion. I did not notice this, because I used a test tube without marks on it. Nice to read that you get rid of all kinds of impurities. If you do this well, then you can get rid of 100% of all insoluble impurities and surely 80% of soluble impurities. But, I'm quite sure that in the toluene solvent, most impurities will be insoluble. With a single recrysallization, where the hot liquid is decanted from insoluble crap and subsequent 24 hour outgassing of small sulpur crystals on a dust-free place, you'll get VERY pure sulphur.
