P2P sintēze no P2NP

[K-Cyanide]

Nē, absolūti tādā nozīmē, ka reakcija nedarbosies, izmantojot nedestilētu P2P, vai ne.
Tomēr galaprodukts vienmēr ir kvalitatīvāks, ja tiek izmantoti destilēti savienojumi. Un nedrīkst aizmirst, ka netīrs P2P, bez šaubām, kaitē iznākumam. Tas ir nogurdinošs darbs, bet tas atmaksājas.

Vai jūs domājat, ka, vakuumdestilējot p2p eļļu/metāna brīvo bāzi, ir absolūti nepieciešams izmērīt spiedienu sistēmā? vai arī es varu vienkārši pievienot vakuuma sūkni vakuuma adapterim jaunā tukšā pieņemšanas kolbā, kad DCM ir destilēts (jo DCM ar zemu viršanas temperatūru 50c pārtvaicēsies pat bez vakuuma), ieslēgt vakuumu, palielināt siltumu, līdz redzu pirmās p2p eļļas pazīmes, kas pāriet uz pieņemšanas kolbu, un turēt temperatūru, līdz destilācija ir pabeigta.

Vai man ir kaut kas jānozīmē vakuuma spiediens?Vai arī es varu vienkārši lēnām palielināt karstumu, līdz redzu, ka saņemšanas kolbā pārplūst eļļa?

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....

Es nevaru iegūt h2o2 30% koncentrācijā. Vai es varu izmantot 12% koncentrāciju lielākā daudzumā? vai ko es varu izmantot h2o2 vietā?

 

[PolandoEmingarnte]

jo Polijā ir nelegāli 30%

 

[amieri]

You concentrate it by evaporating the water out of it.

This is a normal process, don`t worry. Keep adding H2O2 and potassium carbonate.

[amieri]

Is there anything I can use instead of potassium carbonate?

 

[Chemist Jun]

Sodium carbonate

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

 

[GhostChemist]

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?

 

[GhostChemist]

In this video used siphon too

 

[Jack]

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?

 

[GhostChemist]

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

Hello @GhostChemist : Can i use potassium borohydride in this reaction ?

 

[GhostChemist]

Hi
I think yes, but calculate the quantities in mol

 

[Jordan Belfort]

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).

 

[GhostChemist]

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

Other method from using glycidates (without P2NP)

 

[nokospp]

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
