Hello,
I stumbled across an interesting article where the topic of racemisation of l-methamphetamine back to the racemic product is mentioned. Does anyone have experience in this regard?

Seems interesting I'm trying to go deep in the process I will update if I find the correct way for it ;-)
Can't wait to see results
letting your product in solvent in a dark room at room temp will cause it to racemise by itself after a long period of time.I get what this implies but it's an option
? I don't think that works.
Does some of the D need to be present as a catalyst I wonder?
This seems insanely easy to testAt 160 °C, a racemic mixture is reached within 10–20 h, whereas in Arctic regions (−10 °C) racemic equilibrium requires 1–2 Ma
I think it does, I've since read up on the subject and it looks like heat and light drive racemization, it's a concept used to date certain sites by studying fossils of marine animals and such, the principle being looking at the % of enantiomers can tell you how much time has passed since the animal died, since you know most amino acids are used in biological systems as levorotary form,You then look how much dextrorotary amino acid has been formed and from there you can estimate the age of the site, this is very roughly explained, just as proof of concept.So I was wrong just with the light part . Here's some sources, one of them claims, direct quote: At 160 °C, a racemic mixture is reached within 10–20 h, whereas in Arctic regions (−10 °C) racemic equilibrium requires 1–2 Ma.
