I made so many stupid mistakes during those labs.*sobs*
Such as getting unknown acid on my hand, inhaling some diethyl ether, and spilling some of the solution on the floor. Also, I completely lost the amine during the separation process.
Organic chemistry labs are so hard to do!
It was actually pretty simple - just boiling a mixture and isolating the compound with lower boiling point by collecting its vapour. Cold water went though the outter later of the tube to cool the vapour down.
In the end I was able to purify para-xylene to 98% and got a beautiful GC-MS.
