It could be me, but read nowhere a closed flask was used. And why would you? Closed flask if pressure becomes too high the stopper will pop off nothing more nothing less
Hi there!
Yesterday i made a -seemingly- nice 3rd batch. However, after the freezer step, the mixture is somehow ruined by blue discoloration of a substancial
part.
This problem occured the previous 2 batches as well, but much worse than this attempt, and well i'd thought could be anything...
What you are saying is bromine isn't convenient due to smell, NBS due to price, HBr due to volume.
But you end up saying: oxydizing agent + cheap sources of bromine..
Half of bromine or cheap source smells exactly as worse 👻
I'm not a pro, but as far as i can see, you might move the filtering from step 7 to sit in between 5 and 6. since you need to obtain and filter the precipitate before you can do the "quality check".
Ater more than 6 months reading and getting familiar with chemistry, buying all equipment and reagents (except bromine, i made myself), i'm about to follow this video and see if i can get results from it.
1 thing remains mysterious.. Bromine+benzene are added to the drip funnel...
Why is...
Except for the fact that the "chip" in the passport, which holds basically everything you can already see on the document + fingerprints in its memory which is digitally signed by a CSCA (country signing certificate authority) which publicly available public keys are used to verify the...
I just got my 35 % H2O2 (its only 250ml so going to order couple more)
AFAIK, sulfuric + Kbr (or NaBr) is only used to make HBr in situ. Since I got couple of bottles of commercial boiling Hbr i can probably skip the first half ( did a quick test in a test tube and released hell lot of bromine...
Thanks!
If i understand correctly, i could brominate directly using N-Bromosuccinimide as substitute for br2? That would save a tremendous amount of work + easy to obtain.
