Go you Renster! go you!
proud of ya. And you should be too.
I got paid today, getting paid again tomorrow, will have a few hundred quid after expenses, think I'll treat myself to a few things for the lab. I wouldn't mind some carbon disulfide, and I'm running a bit low on dichloromethane. Out of chloroform.
And one other nice thing, although the quantity is showing more extraction pulls need doing, a certain over the counter nasal decongestant, carefully hoarded over a long period of time, after basing the syrup to about PH 11, extraction by means of addition of separate, multiple portions of hot toluene and magnetically stirring to vortex the two phases together, then letting them separate, and using a large separatory funnel to partition off the toluene phase, before dessicating it over quicklime and distilling the tolly off for re-use, acidification of a portion of 0.5ml or so with toluene containing dry hydrogen chloride gas dropwise immediately showed the evolution of turbidity as fine crystals formed in the dry environment, and the main first extraction has deposited what looks to be a good several grams of said nasal decongestant as it's freebase, quite clean looking too, although more extractions, and a recrystallization has been performed, the product salted, washed of any stray organics, (I admit, I am rather pernicketty about my products being purified to a high standard)
Just got to get the rest of the freebase out of the syrup. And of course redistill the toluene for recycling and reuse, so I can get more monetary mileage out of a given bottle of solvent, as I do with almost all my solvents. And redry it each pull with a fresh portion of quicklime, before finally, powdering the spent, hydrated quicklime, and with dry solvent, extract it again with a last portion of hot toluene to free any trapped product.
Because oh me oh my, my poor blocked nose
