Synthesis of Methamphetamine from P2P and NaBH4 Reduction

[hunter12]

Can this synthesis be done in larger scale, like 1-2 kilo

hunter12Yes easily

 

[joker011]

Yes easily

Throw-offI am a chemistry enthusiast from the East. Because I did not receive good education, now I want to learn chemistry. Please teach me, please

joker011If your from the East, go work for "The Company" in the triangle they can teach you far better then most here.

I'm already here now，No friend to lead me

joker011Are you in the triangle?

 

[joker011]

Are you in the triangle?

Asan1973yes，I'm in Laos Special Administrative Region

 

[Throw-off]

yes，I'm in Laos Special Administrative Region

joker011Head North-West then.

 

[joker011]

Head North-West then.

Throw-offI don’t have the skills, what should I do? Be a cannon fodder?

 

[joker011]

Head North-West then.

Throw-off@FFFy054 This is my telegram ， If anyone is willing to teach me, please contact me, please

 

[joker011]

Head North-West then.

Throw-offI just want to learn skills to change my damn life

Can we please have the secret to big nice shards of meth crystals. Tried almost all the recrystalization on the forum but non of them give big crystals.

hunter12You need to separate the isomers. The D and L isomers form large rocks on their own, but not together.

lalalanderHow do you do that?

Hi, gentlemen, you need to dry the reagent before production, but you need to use 40% methylamine aqueous solution, which contains water. What's the use of drying like this?

The reaction mass (RM) in a three-necked flask is filled with water to dissolve the precipitate, then transferred to a separating funnel, and a sodium hydroxide solution is added. The reaction mass should have an appropriate pleasant odor, sometimes with a trace of unreacted methylamine.
Water added to RM


Distinguished experts, I would like to know how much sodium hydroxide solution is added here? What is the ratio of sodium hydroxide to water. Do I need to add sodium hydroxide solution if I extract with DCM like in the video?

Asan1973Water layer must be with alkali pH
ratio of sodium hydroxide to water not important, for example use 10 g NaOH in 50-100 ml of water

GhostChemistHello, experts thank you for your answer. What's the PH? ph 13-14?

Asan1973better pH more than 10
