Hello, I greet you all. I want to share with you my experience with the separation of isomers using L-wine. I did three tests. 2x using methanol when I changed the ratio of free base methanol and tartaric acid in both tests. Both tests turned out basically the same, after combining the ingredients and mixing, a solid mass precipitated, which I filtered after 24 hours. As for the appearance of the product and the overall split isomers, perhaps there was a little more products in one test than in the other test. From 30ml of free base I got about 9 grams of d-meth. During evaporation, when the crystals started to appear, it looked good at first, small needles were formed here and there, but the drier it got, the more it resembled a racemate (ugly amorphous substance). When it dried completely, in terms of appearance, I could not tell the difference between the racemate and this divided product. When it was put on foil and warmed up a little, it was obvious that the crystals crystallize a little faster after dissolution than when it is done with the racemate. From this I concluded that some division took place, but not enough. I note that I did not wash the tartrate powder during filtering. It was not written in the procedure, so I preferred not to do it. Well, now we come to the third test, which I did with the help of water according to the btcboss procedure. After combining all the ingredients and mixing vigorously, after a while I got a thick, really thick mass resembling some kind of cream. It had a consistency basically like the photo that was added by the user Sjeik a couple of posts above mine. I closed the container and let it sit for 24 hours, then I put this substance in the filter and spread it over the vacuum filter and turned on the suction. This thick cream-like substance was really difficult to filter, also in the procedure there was nothing written about washing the tartrate in the filter, so I didn't do it. I only got 11 grams of product from 60ml of free base. But the crystals that arrived were transparent and beautiful. I tried melting them on tin foil to see how fast they solidify and it was really fast like pseudoephedrine meth. So I think that the Split izomer was successful except for the mass tragedy of only 11 grams. The problem was probably mainly that I had a bit of a problem during filtration with the fact that the funnel on the suction flask did not seal well and it might also help to wash off the tartrate salt during filtration, but please advise me how much water I can use for this so as not to disturb the solubility of the tartrate in water and thus did not get L isomers into the product. Well thank you
