Nem, abszolút abban az értelemben, hogy a reakció nem működik a nem desztillált P2P használatával, ugye.
A végtermék azonban mindig jobb minőségű, ha desztillált vegyületeket használ. És ne felejtsük el, hogy a piszkos P2P károsítja a hozamot, kétségtelenül. Fáradságos munka, de kifizetődő.

Oké lesz desztillálni.Gondolom, nincs más megoldás.Gondolod, hogy feltétlenül szükséges mérni a nyomást a rendszerben, amikor vákuum desztilláció p2p olaj/meth freebase olaj?Vagy tudok csak csatlakoztatni vákuum szivattyú vákuum adapter új üres fogadó lombik, amikor DCM már desztillált le (mert DCM alacsony forráspontú bp. 50c lenne desztillálni még vákuum nélkül) kapcsolja be a vákuum kurbli fel a hőt, amíg látom az első jelei p2p olaj jön át a fogadó lombik és tartsa a hőmérsékletet, amíg a desztilláció vége.

Lemaradtam valamiről?Meg kell mérnem a vákuum nyomását?Vagy csak lassan felpörgethetem a hőfokot, amíg nem látom, hogy az olaj átjön a fogadó lombikba?

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....

Nem tudok 30%-os koncentrációban h2o2-t kapni. Használhatok 12%-os koncentrációt nagyobb mennyiségben? vagy mit használhatok a h2o2 helyett?

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
