Moja syntéza 3-CMC

To je skvelé.

Prečo si myslíte, že vám mraznička poskytla počas kryštalizácie čudné výsledky?

ako dobre sa podľa vás táto metóda škáluje?

Kvôli vode, keď jej mrzne, odkiaľ by mali pochádzať kryštály?
Normálna chladnička možno funguje, ale mám v nej potraviny a nechcem ju vždy čistiť.
Skutočne som vyskúšal veľmi veľa spôsobov, ako sa dostať k finálnemu produktu, a tiež som premrhal veľa rozpúšťadiel a 2b3c, ale spôsob, ktorý som opísal, mi fungoval lepšie ako ostatné pokusy.
Takmer som sa z tých rôznych metód pomiatol, všade okolo stáli rôzne malé misky s rôznymi zmesami, vždy som sledoval, ktorá sa vyvíja dobre a ktorá nie.
Napríklad, keď dáte do kryštalizačnej vody/prášku ľadovú ipu, hneď vám vzniknú nejaké biele kryštáliky, ale nie sú číre a je ich len trošku, sp musíte znova kryštalizovať a zvyšok sa musí odparovať, pozrite si posledný obrázok.
Ďalšie 3 obrázky ukazujú, čo sa deje s rm v mojom mrazničke, stáva sa z neho pevná hmota, ktorá sa pri izbovej teplote topí, ale žiadne kryštáliky.

 

[HerrHaber]

it depends on how much material you want to dissolve and the water to alcohol ratio.

Is it possible to make 3mmc in powder ? Everyone is talking about acidification with water or acetone and then straight to dish and evaporate. But maybe it is possible to make it like 4mmc. Just putting HcL straight to washed rm and powder forming. Is it possible with 3cmc ? And how to do it with dcm ?

 

[SunDay]

I dont want to disapoint you, but no... how much i know ( i read all topics about 3cmc). Just evaporation way

 

[SunDay]

But its strange, becouse everythime when i wash stuff with acetone I put acetone to fridge, and after some time i get 3cmc powder. why its not happening when acidifying with acetone from begining..?

 

[HardWork]

I have tried reaction with toluen,and then tried to put only HCL,so I’ve got some powder. But yield was only 25%

 

[SunDay]

I tried this also. 1st time my HCL was 80% (it perfectly fits for H2O acidification in proper amount) but when only HCL, everything BURNT ), and second time with 26-38% so drop was sticky flufy mass(then you need MUCH work to get crystals from this shit, and yeld was about 35%.
By the way, in market there is 28% HCL, it comes from latvia.. that shity HCL makes problem with acidification, purple or emerald color goes on, and really hard to achieve optimal ph. All latvian chem in shops ar shit, so dont be fooled.

 

[HardWork]

Yeah,I have used 26-38% hcl and get 25% yeld.

 

[Jesse_Pinkman_]

Same, always had 25-30% after several washing and recrys...there are methods with more yield for sure, but my experiences were always around this amount
