Ei, absoluutselt selles mõttes, et reaktsioon ei toimi, kasutades destilleerimata P2P-d, ei ole.
Siiski on lõpptoode alati kvaliteetsem, kui kasutate destilleeritud ühendeid. Ja mitte unustada, määrdunud P2P kahjustab saagist, kahtlemata. See on tüütu töö, kuid see tasub end ära.

Okei, destilleerin seda. arvan, et ei ole võimalik seda vältida. kas te arvate, et see on tingimata vajalik mõõta rõhku süsteemis, kui vaakum destilleerimine p2p õli / meta vababaasi õli? või võin ma lihtsalt ühendada vaakumpumba vaakum adapteri uue tühja vastuvõtva kolvi, kui DCM on destilleeritud maha (sest DCM madala keemise bp. 50c oleks destilleerida isegi ilma vaakum) lülitada vaakum kurbeldada soojuse kuni ma näen esimesi märke p2p õli tulevad üle vastuvõtva kolvi ja hoida temperatuuri, kuni destilleerimine on lõppenud.

Kas ma ei ole siin midagi aru saanud?Kas ma pean mõõtma seda vaakumrõhku?Või võin lihtsalt aeglaselt kuumust üles keerata, kuni näen, et õli jõuab vastuvõtukolbi?

Be careful your pump doesn't suck in your product. If you have leaks anywhere it causes air to flow through the system towards the pump instead of holding vacuum. Causes some product to go bye....

Ma ei saa h2o2 30% kontsentratsioonis. Kas ma saan kasutada 12% suures koguses? või mida ma saan kasutada h2o2 asemel?

In general pH should be lower than 7
Acid is needed to destroy residual NaBH4 and for dissolution K2CO3

@ghostchemist.8647 @GhostChemist I would appreciate it if a demonstration was done on how you would siphon liquid with the use of a vacuum pump, it is unclear how that technique is done? Can you link to the technology which achieves that effect? Is it a add on to a pump?

Do you use Hydrogen peroxide and Hydrobromic acid to make bromine in situ because you don't want to deal with Element bromine in a dropping funnel? Can you link to a piece of equipment you use to siphon liquids. A photograph of it? Do you just use a jar?

In this synthesis that is show in this topic bromine and its compounds are not used. This topic dedicated p2p synthesis from p2np.
