Flask cracked in RP/I2 Push Pull Synthesis. How to continue?
« on: July 08, 2011, 01:48:48 PM »
Oh well, a guy I heard about was going the Rp/I2 route with a push pull setup to finally get some honey. He used a 5000ml flat bottom flask and tried to let 178g or Pseudo react. Everything went fine like always, but when phase 2 was ready to kick in, the flask cracked. Luckily this happened not some seconds later, or he might have gotten into big trouble. He took the "always ready for action" wet towels and was able to cool the reaction down, without any further trouble. Since the conversion  did not yet take place, he is wondering about how to continue best from this point?

Did the flask crack gently or did it crack and spill the reactants everywhere? If the reactants are still pure just switch glass and watch temps more carefully next time.

The reactants are still quite rure. He added about 5ml of water though.  Next smaller flask is 1000ml.

Filter out the reaction mixture (if there are glass pieces).

If you seriously can't answer this question yourself get the fuck out.

Lol Damn Sedit. Dont hold back bro...  Hahaha Extreme moderation without prejudice.

Thats the way, transfer to a new flask, add some water and lightly reflux for 12 hours min. Wouldnt even bother filtering the contents as a bit of glass wont hurt and at this stage much can be altered within you mix if you run it through filter paper.

Seriously  though did you try Wetdreams or the-collective with this question?

No there is alot of prejudice going on right now, I truely hate idiots.

He ran 178g Red Phosphorus and Iodine reaction in more then likely an unworthy container under push pull condition meaning that he used very little water. Not only did he not take the time to do it right and reflux it for 48 hours using a long wet reaction but hes damn lucky he did not just blow his stupid ass up due to PH3 build up. Then he shows a complete lack of chemical knowledge by asking simple questions like this which is nothing more then a simple workup.

Iv cracked flask into oil baths and managed to recover material even after the highly basic conditions saponified the oil turning it all into a soapy mess. This guy don't even know how to filter acidic water, concentrate his reactants and start the fuck over.

 I say be gone stupid cook! You have destroyed all of our lives with your lack of knowledge. Best way to continue from here is to get a funnel and beer bong the remaining reaction contents then atlest we all win.

Well, all but almighty sedit thanks for your comments. I am sorry, that I am not a prof in chemistry and 99.9% are also not. I at least ask when being not sure and not bring others and me in danger.
Just to say I did not use an "unworthy container" but a pyrex lab flask.
And obviously you are an idiot for responding like that.
And by the way wetdreams has been archived more than half a year ago
