I trying 4mmc?

[Toddler]

plz check the whole process and plz tell me which step i do mistake, mixture not perform white Flappy liquid.


20g 2b4m
100ml EA
stirrer until dissolve,
Then add 40ml MA 40%.

stirrer 1 hours temp not goes above 30.2. Without water bath.

then put in separating funnel.
first wash once with bicarbonate 5% 60 ml solution,

then 3 time wash with cold water 60ml x 3 times

After wash add 200ml chilled acetone.
Then dropping add hcl 33%.

After some add hcl color change yellow to brown.
Then

But not performing white liquid.
As all saying

All other plz help me.

thankyou in advance.

 

[Dr. MMX]

Its not enough informations to tell you something more. Its chemistry, so guessing is not in the place.
We only do know some details, but I could "bet" that you could exceed temp, pour acetone too fast, not ccorrect stirring, acid too fast

 

[William D.]

For 20g, do the reaction without cooling, repeat the process. But when you acidify, use cooling.

 

[Toddler]

How much below temp,
I take reaction under 20°,
With use 1° ice water bath.

 

[William D.]

This should be enough. But you can reduce the temperature to 10*C.

 

[Toddler]

Ok I tried

 

[Toddler]

@William D. can you Elaborate details of acidification how i do fine.

I think i do some mistake in acidification.

 

[Toddler]

Ptfe stirrer rod or stainless steel rod

 

[William D.]

ptfe bar only

In the initial stages no visible nice layer of the freebase is visible, right?

 

[dodobird]

Nu râdeți, dar am văzut pe undeva că culoarea nu arată nici un meph cum ar trebui după adăugarea ma40 și lăsând să se așeze straturile ... ar putea avea nevoie de încălzire ușoară între 50 și 55 dg reglementate timp de 30 de minute sau mai mult, poate o oră ... astfel încât uleiul formează frumos bogat de culoare profundă galben închis pare cel mai bun din ceea ce am citit, dar cei mai mulți oameni obține maro în funcție de bk4 achiziționate și alte reactiv de calitate. Apoi se spală de 3 ori și se pune în congelator/frigider timp de o oră înainte de a se acidifica la 5,5 picătură cu picătură ... ce spuneți?

 

[dodobird]

What did your 2b4m look like ...can u share a pic, please?

 

[William D.]

EA cu metilamină aq. devine aproape omogenă la agitare. Acesta este principalul motiv pentru o reacție rapidă. Dacă există probleme cu separarea, puteți utiliza încălzire, saramură sau EA suplimentar.

 

[Toddler]

@William D.
EA with aq. methylamine becomes almost homogeneous when stirring.

How much temp range ?

 

[William D.]

It should start at 40*C and not allow to boil

 

[dodobird]

Was talking to the original poster but since u replied, care to share a pic?

 

[dodobird]

Meph and or ma40 likely culprit, his 2b4m don't look that good afaik

@William D. @Dr. MMX


I cooked one more batch.

150g 2b4m
600ml EA

300ml 40% MA aq. ( take 10min gap every after 50ml add 6x50ml)

after that left stirrer 2 hours temp range 20-30 using ice batch

(should this be done this way)

added 5% sodium bicarbonate once with 450ml water

and after that washed 450ml water x 3 times.

kept it in fridge for 8 hours at 1• degree temp.

after that add acetone 800ml within mixture -18 degree

stirrer 5 min mixture temp -10 degree.

then add HBR 48% 50ml drop wise until ph become ph5.

I have found what is in the image.

In this small crystals are made of small like needles

 

[dodobird]

So far it looks great bro..congratulations...

What did you do once you reached the above image?

Fridge 8 to 10 hours?
