A good method to use triethylamine if you want to get a dry alcohol methylamine soln.

Your 300g methylamine gas is it mean use cas 593-51-1 dissolve in methanol?

 

[G.Patton]

Hello, no. Every substance have own weight. Methylamine has gas form at normal conditions. 300g of methylamine free base (gas) has to be dissolved in methanol.

1) cani direct use methylamine solution40% dissolved in methanol?
2) the last step can i change use rator vapor to clean water, methanol and dcm to get mdma oil?

 

[G.Patton]

1 - yes
2 - I don't understand your English

A vacuum distillation setup is prepared. Methanol, DCM, water and other low boiling substances are distilled off at 130 °C firstly. Then, a heater is set at 165 °C, little drops of MDMA oil are condensated and seen around 140-145 °C; at 160-165 °C (20-18 mbar) MDMA oil is distilled intensively. The clean MDMA free base distillation yield is ~ 1.0 L.

A membrane vacuum aspirator is sufficient to distill off water, methanol and other low boiling substances from the reaction mixture. A decent vacuum pump is recommended to distill MDMA free base.
This step can i use rotaryevaporator?

 

[G.Patton]

yes, you can

Orite thanks

A very high initial temperature for these solvents, especially using a vacuum. And it is better to exclude water with drying agents if you want to get the maximum yield. In addition, you can extract amine in the water layer and already work with the water layer, the dcm will take the impurities, and you can avoid distillation if your raw materials have been of good quality.
