For everyone running into green,red or purple MMC on DCM

[TheVacuumGuy]

You will often get these comments or questions:

• Unreacted methylamine ?
• Unreacted bromoketone ?
• Acid added too fast ?
• Temps too high ?
• Bad XYZ?​

The answer to above questions is : probably not.

The colorations are caused by acidification in acetone. How and why is yet to be determined.

I've tested this multiple times, by dividing the freebase in 2 equal portions and using different solvent for acidification.

In acetone i could throw away 4 out of 5 because of green/red/purple.
Other solvent yielded 5 / 5 perfect white.

Video/photo's will follow

So what solvent do you recommend other then acetone?

 

[TheVacuumGuy]

I wouldn't recommend anything yet, since i'm talking about specifically the colorization issue. Using different solvents pose other problems further up, But in this case it is ethyl acetate

Because much chemia they dont know what they do dont need made powder can made from freebase crystal they u dont lost time to filtr powder wash him when u get puree mmc HCl crystal total time synthesis can be max 3h

 

[TheVacuumGuy]

Good chemists also share knowledge. And those crystals are full of dirt.

 

[$!$]

Yes dirty like i say xad

 

[Dr. MMX]

I dont see any dirt there, it may look like that based on light and elements near in the room

 

[TheVacuumGuy]

I don't see any ontopic answer. Only trying to sell his synthesis services for multithousand dollars.


Well, not needed:

Veryy good 1 WHO made it good prima

My son, can you tell me how you got that milk so white ? I know kids don't like hearing their parents talking about this but I only get my milk that white when sleeping with my wife. Really easy to do for me.

 

[Throw-off]

So what solvent do you add into the MMC freebase.

 

[Throw-off]

Oh its ethyl acetate

 

[Dr. MMX]

I am really sorry but I just cant agree what your saying. Why acetone is that?
it depends what solvents your using and whats your synthesis procedure. Its not acetone that is a problem but a technique.

Sometimes when I did some mistakes during syntesis, I had these colors, but its just about bad reaction most liekly, or exceeding temp or doing something not smooth. Since some time I always get same result, I use acetone. Acetone has to be ice cold, added to cooled mixture, while stirring.

Because of aldol condensation.
