UWe9o12jkied91d Kifejtené, kérem, részletesebben az Ön és mocnykutas által tárgyalt módszert?

Köszönöm

Nem tudom milyen eljárással dicsekszik folyton, de most a legjobb eredményt úgy értem el, hogy a keton egy kis dcm-ben feloldottam, kissé felmelegítettem 35-40-re, egyszerre hozzáadtam a metilamint, hagytam 10m keverni, ahogy van, majd 20-30perc alatt apránként adagoltam dmso-t. Ezután víz hozzáadásával és némi etil-acetáttal együtt még pár percig kevertem, hagytam elválni. hideg acetonnal hígítottam és kicsaptam, 33 és 37,5 HCl-t is próbáltam, nincs érezhető különbség.
Az összes általam követett eljárás közül ez volt a legtisztább és a legnagyobb hozamú, és mellékesen azt hiszem, minél nagyobb a skála, annál jobban működik.

Miért adjunk azonban az öblítéshez vízzel együtt oldószert is? Noob itt
Mi uf kiindulási oldószer EA helyett DCM?

Dod anyone have tried this recipe???

Where can I buy benzene/Benzol in Germany anonymously?

 

[dnBQByvHb8Zkawbjpx]

Benzene is rather restricted in the EU. You may be able to find a seller but as an individual consumer you'll have a hard time justifying the purchase of more than limited quantity. Ethyl acetate is a solvent for making 4MMC that can be obtained the easiest, is fully legal and not restricted, and is quite cheap.

 

[frosties]

Thx I'll go with you his method.

 

[dnBQByvHb8Zkawbjpx]

Do you have experience with recovering solvents through distillation? DCM is moderately difficult to obtain (restricted for consumers in the EU) and NMP is expensive, so reusing them could be an interesting option.

Wow, that yield is massive. Are there any alternatives to NMP to work as a phase transfer catalyst? I've read that it could be substituted by DMSO, are there any other options that may be cheaper and more easily available?

I don't understand why solvents are not reused on a larger scale as well - it limits the volume of waste and brings down the cost.

Some impurities stay in the solvent so distillation is needed for reuse and it takes a lot of time and need large equipments. For legal businesses it's possible but for drugs way more complicated (time, space, electricity consumption, etc)

 

[dnBQByvHb8Zkawbjpx]

I understand that and I had distillation in mind to recover pure solvent. Especially DCM with its boiling temperature of 40 °C requires almost no energy to distill. I'm definitely going to do that and in about a month I should have some first-hand experience to share.

Hi. This post made months of reading confusion go away, very straightforward, thanks @Madre . I had some important doubts to be cleared for upcoming MasterChef tryout , appreciate guidance on them. Here we go...

1. Can I replace the benzene with say 300 ml Ethyl acetate. If so what proportion would be ideal and if any procedural changes needbto be made, I am guessing not.

2. Is it Hcl38% we should use?

3.Does the methyl gad need to be relased after animation at all or do we just pour it in shake and then seal to put in the fridge?
How can I reduce this stage to under 1 hour or 2. Any temperature rise monitoring or precaution until this stage? Max temp?

4. Do we need to was the freebase during flushing, with nac03 plus water first and then 2 x with distilled water?

5. Is this method of preparing the 10-90 Acetine hcl38 solution and adding together, better yielding or beneficial over the much common separate addition method of acetone and hcl38? Does it affect quality potency or failure chances or perhaps yield weight of final powder 4mm

6.... Please share equationally correct reagent and chemical quantities for making 10 kg a day. Also any simple apparatus methods for doing this quantity without much labware beside basic flask and jar. What reaction container could I probably use to replace a reactor etc etc


THANKS YOU VERY MUCH IN ADANCE , GREA JOB!!!
