boris_73 Posted September 21, 2004 Posted September 21, 2004 this is just a thought if you were to make nitrocellulose could you reuse the 50/50 sulphuric acid/nitric acid mix after you all ready nitrated some .5g cellulose to make some more nitrocellulose
Gilded Posted September 21, 2004 Posted September 21, 2004 From what I've understood, the nitronium ions that sulphuric and nitric acid creates are mostly used when you nitrate your cellulose, so it's not probably too effective to reuse the solution. Not sure about that though, I think we once again need someone more reliable to confirm this. Edit: I bet you could try nitrating stuff with the solution that's left if you didn't nitrate too much cellulose, to a point they are not being nitrated anymore.
boris_73 Posted September 21, 2004 Author Posted September 21, 2004 yes that is what i thought, i just needed somebody to clarify it
budullewraagh Posted September 21, 2004 Posted September 21, 2004 it depends on how much sulfuric/nitric you made
Gilded Posted September 22, 2004 Posted September 22, 2004 Yep, bud's right (and that's what I meant). If you made like a liter of the stuff and nitrated .5g cellulose, then you definately have some nitronium ions going on in there. You might as well nitrate something else too.
YT2095 Posted September 22, 2004 Posted September 22, 2004 it`s not that easy to make a safe batch, don`t forget you MUST neutralise ANY remaining acid, otherwise it becomes VERY unstable!
boris_73 Posted September 22, 2004 Author Posted September 22, 2004 i know all the procedures 2.5ml/nitric acid 2.5ml/sulphuric acid add .5 cellulose let it nitrate for 5minutes then boil it in sodium bicarbonate solution and rinse with distilled water untill it tests for neutral etc if you make large quantities it may result in a run away as well thats way if you were to make it make it in small quantites, and its nice to see you yt not heard from you in a while
YT2095 Posted September 22, 2004 Posted September 22, 2004 OH BOY!, a runaway reaction is something you DON`T want to see as a newbie!, it`ll scare the crap outa ya! esp when you know what they CAN do! 9 times outa 10 you`ll just generate alot of gas and heat and ruin your experiments and product, the other 1 time, BOOM! and hot acid all over the place ( NC is NOT a synth for beginners! (or anyone really) best leave it too the pros and buy it from the shop!
Gilded Posted September 22, 2004 Posted September 22, 2004 Umm, have you tried it YT, and yet lived to tell the tale? Or was it just a small quantity? I wonder if hot acid is good for PINE TABLES. Next time on SF: Nitrating toluene next to burning sparklers in a moist room with lots of cesium lying around!
boris_73 Posted September 22, 2004 Author Posted September 22, 2004 thank you for your concern but i have made it before and the very most important things are dont let it get over 70C during nitration make sure you neutralise it and dont make large quantities and i think .5g isnt exactly large quantities is it. 5ml for every .5g thats what i would use
boris_73 Posted September 22, 2004 Author Posted September 22, 2004 plus nitrocellulose is one of the more safer nitrations
