do you know how to prepare 2b4ch in a crystal for dissolution in toluene? Since so far I used 2b4ch in powder which was ready for use, now I will use imported bromine in a crystal and something needs to be done with it to make it ready for use, the last issue is the question about crystallization. when I cook our cmc at 80 degrees for a few minutes, how much water should I add per 1 kg of 2b4ch, assuming that the efficiency is 60%? Is it better to add alcohol?

This makes not much sense as I remember the parachlorophenylbromoketone is solid and "imported bromine in a crystal" I don't exactly know what you want but you insinuated that the ketone is already brominated and bromine is one of the two single liquid elements at r.t. but most importantly you must know why you need it for (idk)... I'm not using toluene so I have no idea but many water washes are advised and alcohol would certainly mess up your workup as I imagine.

explain differently. Last time I received 2b4ch in powder and it was of average quality, this time I will get 2b4ch in crystal, what do I need with this crystal before the extraction of 2b4ch in toluene takes place?
