Nie, absolutnie w tym sensie, że reakcja nie zadziała przy użyciu niedestylowanego P2P, czyż nie.
Jednak produkt końcowy jest zawsze wyższej jakości, gdy używa się związków destylowanych. I nie zapominajmy, że brudny P2P bez wątpienia wpływa na wydajność. To żmudna praca, ale się opłaca.

Czy uważasz, że absolutnie konieczne jest mierzenie ciśnienia w układzie podczas destylacji próżniowej oleju p2p/oleju metylowego freebase? Czy mogę po prostu podłączyć pompę próżniową do adaptera próżniowego na nowej pustej kolbie odbiorczej, gdy DCM został oddestylowany (ponieważ DCM o niskiej temperaturze wrzenia 50 ° C destyluje nawet bez próżni), włączyć podciśnienie, podkręcić temperaturę, aż zobaczę pierwsze oznaki oleju p2p docierającego do kolby odbiorczej i utrzymać temperaturę do zakończenia destylacji.

Czy czegoś tu brakuje? Czy muszę mierzyć ciśnienie próżni? Czy mogę po prostu powoli zwiększać temperaturę, aż zobaczę, że olej pojawia się w kolbie odbiorczej?

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....

Nie mogę uzyskać h2o2 w stężeniu 30%. Czy mogę użyć 12% w większej ilości? Lub czego mogę użyć zamiast h2o2?

In the video says add hcl until ph 4 - 5 even less.
But in here Says ph 7 - 6.5
Which one is right?

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.

What reaction would you suggest to make a onepot (can be barbier-alike) P2NP to P2P which runs at elevated temperature's or room temp.
Iron and aqeous HCL requires refluxing, it's possible at ibc tote but if leak occurs it's finished.

This isn't scaleable to IBC tote. Using other reductant can overreduce (F.E. magnesium in methanol).

Scalable and control reactions for produce P2P from P2NP is the process with NaBH4

Other method from using glycidates (without P2NP)

i just perform this synth and failed in h2o2 addition
for anyone trying this method you should try to make it as cold as possible during h2o2 + k2co3 addition if you didnt have patient and poring h2o2 way to fast it will burst out
