Hi! What do you plan to obtain from p2p? Amphetamine or Methamphetamine?

A white powder is obtained via rinsing anhydrous cold acetone or recrystallization. But it turns yellow again during prolonged storage.

You can use any type of alcohol here: MeOH, EtOH or IPA

Yes

Yep You can use the chloroform as extragent

Steam distillation is more safer than direct vacuum distillation

Introduction Amphetamine and methamphetamine are the most popular synthetic substances and both of them have significant value in modern drug sosiety. They are used at raves, parties, as doping, to get a high and so etc. BB Forum is unique platform in the World, which implements studies of these...

Simply adding ammonia is not sufficient, because the process is rapid. It`s possible that with excess pressure, the product yield may be increase.

Thanks! The pure white color amphetamine presented on our video https://bbgate.com/media/amphetamine-synthesis.70/

I recomended the recrystallization of obtained metamphetamine hydrochloride from the pure EtOH, MeOH or other solvent.

7.2% of methamphetamine remains in the grey sluge of Al (Fig 6, filter) if it is not washed with solvent (EtOH or IPA)

It`s an interesting study, but even in the tables, the experiments were not identically. For example, in experiment where Ammonium carbonate 5 eq + Formic acid 5 eq, the reaction time is 8 h, while in another experiment it`s 14 h.

Hi! Thanks, Scheme 1 is corrected. Nucleophilic properties are also an important parameter, but ammonia is a very volatile reagent that is ligter than air. Therefore, during the local heating on amalgam centers, evaporation will occur of ammonia.

Hi! Yep, Fig 13 is a pure P2P with SiO2. If using rotovap, the process will involve water and P2P disstilation as mixture too.

The reactions proceed according to Scheme 1 Reagents and materials: 1-Phenyl-2-propanone (P2P) 5.4 ml; N-methylformamide 13.4 ml; Sodium sulphate (Na2SO4); Hydrochloric acid (14% aq HCl) 32.1 ml or 20 ml 44% sulfuric acid H2SO4; DCM 100-150 ml; Sodium hydroxide (NaOH) 9,6 g in 24 ml H2O...

Hi, alterego! Yep, that the fact pure Amfetamine have a white color. The yellow color of Amfetamine is specifically due to its oxidation. For example, during the evaporation of the solvent at its boiling and during storage with exposure to air. Additionally, the yellow color can be attributed...

The reactions proceed according to the Scheme 1. Reagents and Materials: Aluminum foil 14 µm, 6 g Mercury(II) chloride, 0.05 g Distilled water, 2-3 liters P2P (from p2np via NaBH4 reduction and steam distill) 5 g Aqueous methylamine 39%, 15 ml Sodium chloride, 5 g in 15 ml water IPA (isopropyl...

Reactions proceed according to Scheme 1 Reagents and Materials: 8.1 g of aluminum 0.05 g of mercury(II) chloride 5 g P2P 2 g of hydroxylamine or a mixture (50-60 ml of IPA (or ethanol) + 2.5 g of NaOH + 4.55 g of hydroxylamine hydrochloride) 50 ml of ethanol 2-liter flask 2 liters of ice-cold...

Vielen lieben Dank!

Hi! In principle, it is possible to carry out the process on 1kg, but it is necessary to consider significant heat generation, so an efficient cooling system is required in the reactor.
