In this step, it`s probably to leave RM for 2 days is a mistake

It`s not necessary to evaporate IPA, but the T of mixture must be raised to 60C. If the all chemistry is pure, that possible too much of CuCl2 could have reacted with amine. Can you describe the colour of the mixture when adding CuCl2?

I agree with mithyl2 It would be nice to see the photo of your P2NP

Of course, it`s possible to substitute alcohols. DCM and IPA are mixing. While EtOH can be "washed out" by water.

The process is not entirely precise, and there will likely be a large number of co-products. A mixture of halogen derivatives is formed (Cl-CH2-CH2-CH=O and CH3-CHCl-CH=O). Acrolein and its chlorinated derivatives can polymerize, forming polymers and hard-to-remove resins. In the final...

Hi! See attached files. Vacuum pump as example and technical scheme to suck the Rm into another flask

SiO2 needs be purchased. It is a good absorbent in synthesis. This stage drying methylamine in MeOH or IPA, cooling is not necessary. Carry out the process in a separate flask or bottle (polypropylene or glass) with germetic cork. In this flask add 20-30 g Na2SO4 angydrous + 20 g SiO2, next add...

Birch reaction will be later

First stage: Drying reagents, Imine preparation and Reduction. Proportions for 10 g of pure P2P (after distillation add SiO2): 1,1 g NaBH4 powder 20 ml of 40% methylamine in methanol (methanol saturated of methylamine) or 23-25 ml of 30% methylamine in IPA 20-50 g or more SiO2 20-30 g or more...

In the next step I recomended carried out a trial synthesis of meth for your experimental expirience. How many g of P2P you willing to trial synthesis? P2P should be pure (steam distillation will be applied). You will need of drying agents such as SiO2 (silica gel) and angydrous Na2SO4 (sodium...

Very interesting job

I think yes. We working with PMK too.

Is this amalgam synth with nitromethane as a solvent and donor of methylamine?

Also, it`s necessary to consider that nitromethane is explosive and can burning in the non-availability of air oxygen

Hi! Yep and ethylacetate

I recomended using the method with NaBH4. Spoiler: a video of this method will be available soon. You also need to obtain a methylamine solution in alcohol (methanol or IPA) from methylamine hydrochloride. Can you do this stage...

When loading into 200l reactor, temperature control of this reaction will be inherently impossible, even with the use of refrigerants

Thank you for your attention, the mistake has been corrected. The reagents are indicated taking into account the experiments which were conducted.

Have you any of the next main reagents for provide conversion p2p to amph or meth: NH3; HgCl2 or other Hg salt; Formamide or ammonium formate; NaBH4 the best variant if you have it; Methylamine Hydrochloride?

I advise to produce methamphetamine. Because, the methamphetamine is more stable than amphetamine. https://bbgate.com/threads/methamphetamine-and-amphetamine-syntheses-methods-comparison.8635/#post-41733...
