Dlaczego używamy dcm zamiast toluenu i jaka jest tego zaleta?

Definitely dries fast if that part includes evaporation....or just because... it works. You can use toulene it you want

więc nie potrzebujemy nawet chłodnicy zwrotnej i możemy gotować tylko przez półtorej godziny, a nie 24 godziny? dlaczego wideo jest włączone, jeśli czasy gotowania są nieprawidłowe, a on nie refluksuje? czy to w ogóle zadziała? po co umieszczać fałszywe informacje, czy możemy uzyskać lepszą metodę niż ten facet na filmie, jak możemy przeprowadzić reakcję z refluksem dla małych partii przy użyciu produktów otp lub jak etis wideo mówi, że nie musimy nawet refluksować, jestem bardzo zdezorientowany, dlaczego administrator pozwoliłby na użycie tak kiepskiego wideo na tej stronie.

As you can see the reaction was refluxed.... look at all the beads of water condensing on the flask walls... just not a heavy reflux.
Tutaj jest mowa o racemicznej lub syntetycznej efedrynie. Czy zamiast tego możemy użyć Psodoephedrine?

Czy ktoś może odpowiedzieć na to pytanie?

Yes pseudoephedrine HCL works perfectly fine also... same exact way.. follow the same steps
Jeśli dodam wodę i chlorowodór w celu zakwaszenia wolnej zasady podczas tworzenia wolnej zasady, oddzielę warstwę wody i całkowicie odparuję wodę, czy na końcu pojawi się sól? Teoretycznie chlorek wodoru nie jest potrzebny?

Gdy wolna zasada jest ekstrahowana za pomocą DCM, można użyć wodnego HCl do uzyskania soli po odparowaniu

Titration
DO VERY CAREFULLY TO AVOID "OVER-ACIDIFICATION"
Prepare a 25 ml D-h2O and 5 ml HCl (aq.)
To your NP solvent + FB meth, add small amount of D-H2O , like 20 ml and 2 drops
of the above dilute-acid prepetation
Shake
After layers separate, extract out the water+meth HCl layer with eyedropper pipette
And then evaporate
Repeat 2 - 4 times
*You want the pH level to be as close to 6 as possible !!!! A pH of 5 won't kill you but take caution
** Evaporate VERY LOW HEAT AS POSSIBLE to avoid loss of yield
Or evaporate under a fan or a hairdryer
*** You could titration with sulfuric acid to get methamphetamine sulfate
****"You could just add lemon juice
to your NPsolvent/FB meth and extract the lemon juice+meth citrate and drink "tiny eyedropper 1-3 mls" and get high oral administration

Is this method applicable to the synthesis of ephedrine extracted from Ephedra sinica?
Take a look if you can get "Rhinopront Kombi" pills, they contain 60mg of Pseudo and 2,5mg Triprolidine.
Online pharmacys sell them for half the price you pay in normal pharmacy stores. Pharmay stores also just sell one or max. two packages of it, online pharmacys sometimes sell 1-2 packages more. It's great if you have some friends / other people ordering them from different online stores. But never ever order it to the address where the "magic" happens, should be clear.
These pills are super easy and great for extraction and you'll get super high quality of Pseudo if you take some time into washing / cleaning / recristallization of the product.
Grind the pills in an electric coffee grinder and extract 3 times with denatured alcohol, do a 12-24h soak in xylene e.g., after that wash it by stiring 5-10 minutes in hot/boiling toluene(using a magnetic steerer with heating for example, 2-3 times with fresh toluene and take care for very GOOD ventilation!), then wash with acetone and recristallize from hot methanol or ethanol. You can get super clean, large crystall-needles of Pseudoephedrine that way.
All solvents should be as dry as possible, e.g. by drying with molecular sieves.

That's music to my ears ! They're also very affordable too and of course I'll take your tips into consideration, thanks Bro !
If you are located in Germany this is by far the best way to get Pseudoephedrine by extraction. All the other Pseudo medication and pills like "Reactine Duo" are totally crap and full of additives which makes extraction for obtaining good and clean Pseudo almost impossible.
And like I wrote, if ordered in online pharmacys "you" are able to order easily 3, sometimes 4 packs for roundabout the half of the regular pharmacy price, while some pharmacy stores in the city don't sell more then one package at a time.
I don't know how the situation looks by now, but several years ago ordering them in the amount I wrote was absolutely no problem.

Request for help: I have obtained ephedrine oxalate. Can I follow your steps exactly to produce methamphetamine? Or will I need to convert it to ephedrine hydrochloride?

Requesting your help: Does this mean that I can use oxalic acid ephedrine to synthesize methamphetamine following this route?
No, using carboxylic acids (ephedrine salts) remains undesirable for this reaction. You need to obtain the hydrochloride from the oxalate to avoid problems.
