If this mixture (which hasn't solidified any) was left sitting for a while, would the excess bromine evaporate away, crystalizing the product?
After all washes and an a/b, the 2c-h freebase was still on the dark side, but clear. It's very abundant and overwhelmingly bloody looking.
Of course that would be excess bromine too.
When a certain procedure calls for the removal of solvents under vacuum, is it really necessary? In this scenario, many writeups have removed solvents such as DCM under vacuum. The available pump was too strong, so the dcm was stripped at atm. I didn't see how this could be bad as I assumed the feebase wouldn't be harmed by temps that low. Is this not the case? I read:
the solvent removed under vacuum and the residue was distilled at 6 mmHg to give 16.8 grams of 2C-H as a yellowish oil (65%).Have you ever had really pure mdp2p, almost colorless, the faintest hint of greenish clear, and heated it up to distill it again for extreme purity, and notice upon heating the ketone in the boiler flask, the color went from near clear, to very distinct yellow/gold??? Maybe thats why my 2c-h came out darker than the person who vacuum distilled his solvents off?? Heat discoloursation?
