If you neutralise amphetamine with oxalic acid, you get amphetamine oxalate. However, this is not recommended as oxalates can lead to kidney stones.

The octan rating of gasoline is measured in octane, so I think you have heared about a hoax. Apart of this, @Frit Buchner descriped the advantages of the racemate cleavage, which is a suitable way to increace the potency of your stuff.

Hi! A one-pot synthesis to meth does not work, but you could first reduce the P2NP to P2P and then use it to produce methamphetamine. A method using iron and HCl is described here: P2NP reduction to P2P using iron Since iron is magnetic, you need a KPG (overhead) stirrer. It is also possible...

How did you remove the top layer? If you pour it off or picked it up with a syringe, you will lose a lot of product. It is better to use a separating funnel (at least 500ml, preferably 1000ml). It should be large enough to hold the entire reaction mixture and still have 1/4 space at the top...

Sodium hydrogen sulphate can be used instead of sulphuric acid. If sodium hydrogen sulphate and sodium chloride are mixed together in a glass container and heated, sodium sulphate and gaseous hydrogen chloride are formed: NaHSO4 + NaCl -> Na2SO4 + HCl

This method should work, but you must bear in mind that it does not result in P2NP. Phenylnitropropanol is a β-nitroalcohol that contains a hydroxy group (-OH) on the carbon atom next to the nitro group (-NO2). The general structural formula is C6H5CH(OH)CH2NO2. P2NP (1-phenyl-2-nitropropene)...

Hi! This is not correct, as you are only comparing ammonium acetate with n-butylamine. The difference is the combination of ammonium acetate in acetic acid. Ammonium acetate is hygroscopic (therefore it has a tension to dissociate only by presence of the undried solvents or air vapours) and...

Hi, Did you keep in mind, that when using DCM the organic phase with your product is usually the lower layer and the water floating on top? If you respect that, there a serval issues here anyway. Frit was on the right way, but you have used way too much Methylamine. The stoichiometric ratio of...

Then just give me one good reason why that shouldn't work?

Hi! Does it just look like that, or do you have too little oil in the oil bath? It should be as high as the level in the flask. And you have to make sure that it stays that way. This means that if the water level in the flask rises above that of the oil, you have to heat it up sufficiently...

It would help if you describe exactly how you proceeded, what purity your reagents have, how large your batch was, etc...

Mylar bags are not a challenge for x-rays cus it is a thin material with a low density. The higher the density and thickness of the material, the more radiation is absorbed. Of course, energy also plays a role, but this is not a decisive factor with modern X-ray devices. Some Mylar bags are...

Acidification and pH adjustment are not the same thing, because pH adjustment can also mean basification. As different salts have different physical, chemical and pharmaceutical properties, it is better to choose a suitable salt. Amphetamine acetate has no practical significance (except, for...

I will do research to get rid of the pharmaceutical industry's favourite excipients. Polymerised sugars, modified cellulose, povidone and other devilish additives that spoil the fun. Enzymatic hydrolysis sounds promising for some of them.

Maybe you're able to answer your question by yourself: What do you think is the nasty shit that evaporates? a) potent amphetamine freebase, because it is more blessed to give than to receive b) inpotent solvent that pays my bills? Choose one

I really can't understand the euphoria here. The end product looks terrible and the impurities are visible to the naked eye. I wouldn't even take this if I were paid for it. The cleaning of the intermediate product and the free base is supposed to be a joke. Why does everything always have to...

Ich hoffe das ist nur ein Witz... Wenn du die beiden Zucker entfernst, bleibt nur das leere Fläschchen übrig. :D

In order to dilute 150ml of a 22% ammonia solution to a concentration of 10%, you can use the dilution formula: Where: C1 is the initial concentration (22%) V1 is the initial volume (150 ml) C2 is the target concentration (10%) V2 is the target volume, which we want to calculate. First...
