Help 4mmc shake and bake final step !

[ymaaah]

When I put HCl and acetone to my 4mmc freebase, nothing change except the pH, my pH was pink/violet, I checked on google and I have 3-5 pH, so its a little less than 5,5-6 but it changes nothing no? https://ibb.co/NrSCz7p

My solution is very yellow and there is 2 parts, I put it in the freezer and I will wait tomorrow but idk why I have this color.. do you know my error ? I divised in two parts the methylamine/water (I threw it) and 4mmc and I drop the HCl first, but maybe I dropped to quick..? And after I put acetone, but the pH returns to 7 so I put again HCl and I putted it to the freezer https://ibb.co/wYvYCbL

sorry for links but BBgate for me, has a lot of problems in the console (matomo, extensions ect) so I cant post pics .. ibb.co is imgbb check on google

This way is shit u dont made good mmc this way is no posiblem

from where did u bougt 2b4m?a lor of users have the same issue

 

[ymaaah]

constantilyous777 but mine is pure, white crystals and rocks, all my steps are perfect except the last, when I separate m40 and 4mmc freebase, I put 5,5ml of HCl (for 10g of 2B4M) and after I add 50ml of acetone and nothing changed, just vapours (I have a ABEK1 mask so I didnt inhale), its weird because after my solution was 2 parts so its very strange.. The colour of the 4mmc freebase, even the texture should changed but no..

I putted it in the freezer and at the morning I took the glass and I saw a bloc of 4mmc :

I broke the bloc and putted it with acetone approximately 20ml for I think 2-3g, I mixed and putted in a filter, the liquid in the glass was clear yellow and 4mmc was very white, not powder but a paste : https://ibb.co/DtrJwXT https://ibb.co/tsQ16qm

How much u get gram powder mmc ??

 

[ymaaah]

Idk, im at work and I putted my plate at the freezer at 11:00am, I will tell you when I will baack to home in 2 hours, but probably max 2,3g pure 4mmc, it seems to be more when you look at the pic but this 4mmc wasnt pure and dry

 

[mocnykutas]

FForm 10g 2b4m ?? 3 g powder haha

 

[w2x3f5]

After amination you bad wash with water, because if you take 2b4m 10g = 0.0438 mol, but if you use HCl acid around 12 mol/liter and you spent 5,5 ml HCl = 0.066 mol
Its mean around 1,5g MeNH2*HCl you have inside your powder
How many percents HCl acid you used?

 

[bmkadbbsupplier]

sir we can supply high quality 2b4m cas no 1451-82-7,

 

[ymaaah]

yeah this is my first time with synthesises, if you make 10g 4mmc from 10g 2b4m, good for you, im glad, but we dont care bro, I think your parents didnt give you love and attention, poor kid.. be cool, this is not a competition, there are better chimists here than you, so be normal, not a idiot )))))

 

[mocnykutas]

Normal u get minimum 6.5g crystal i get 8.1g powder 7.7g crystal

 

[ymaaah]

my method is not perfect I think I dont have the accurate method, when I putted hcl ans acetone, there was 2 parts I don’t understand why and the bottom part didnt changes into 4mmc nvm, maybe next time I will be better, maybe you can write me accurately the last step if you are an expert, M.Heisenberg?

 

[mocnykutas]

Im nerd
I use NMP 20min and have freebase

 

[ymaaah]

I forgot to tell when I added hcl and acetone, I didnt mix so laybe this is why, so maybe my pH wasnt good, idk

 

[w2x3f5]

because need read good ))) but when I repeat you understand )

 

[ymaaah]

Yeah this is my nature ) I cant be concentrated longtime and I forget a lot of things so ..

 

[ymaaah]

https://ibb.co/y6ndQv0 this is my result, very white I like it (even if M.Heisenberg get 8,1g powder for 10g ), im glad

 

[w2x3f5]

now can do good crystal from hot vodka )

 

[ymaaah]

I have pure IPA, its not better? The method is different I suppose?

 

[ymaaah]

I make again a synthesis bur this time I have a perfect white milk

https://ibb.co/K7sY16j https://ibb.co/029xBJn I hope I will have a good yield but I think its good, my error was that I add quickly HCl and I didnt check pH sometimes, so add drop per drop (with a syringe) HCl and mix slowly, this time my pH was 3-4 I think, then add acetone and mix still slowly, you will see rocks and the mixture will be white LETSGOOO

Yield?
