Nu, absolut în sensul că reacția nu va funcționa folosind P2P nedistilate, nu-i așa.
Cu toate acestea, produsul final este întotdeauna de calitate superioară atunci când utilizați compuși distilați. Și să nu uităm, P2P murdar afectează randamentul, fără îndoială. Este o muncă anevoioasă, dar se plătește.

Credeți că este absolut necesar să se măsoare presiunea în sistem atunci când se distilează în vid uleiul p2p/meth freebase? sau pot doar să conectez pompa de vid la adaptorul de vid de pe balonul de primire nou gol atunci când DCM a fost distilat (deoarece DCM cu o temperatură de fierbere scăzută de 50c ar distila chiar și fără vid), să pornesc vidul, să măresc căldura până când văd primele semne de ulei p2p care ajunge în balonul de primire și să mențin temperatura până când distilarea se termină.

Îmi scapă ceva aici? Trebuie să măsor presiunea vidului sau pot doar să măresc încet căldura până când văd că uleiul ajunge în balonul receptor?

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....

Nu pot obține h2o2 în concentrație de 30%. Pot folosi o cantitate mai mare de 12% sau ce pot folosi în loc de 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
