Minu 3-CMC süntees

[mithyl2]

see on suurepärane.

miks te arvate, et sügavkülmik andis teile kristallisatsiooni ajal kummalisi tulemusi?

kui hästi see meetod teie arvates skaleerub?

Kuna vesi, kui selle külmutamine, kust peaksid kristallid tulema?
Tavaline külmkapp võib-olla töötab, kuid mul on minu toit sees ja ei taha seda iga kord puhastada.
Ma tõesti proovisin väga palju viise, et jõuda lõpptooteni ja raiskasin ka palju lahusteid ja 2b3c ka, kuid minu kirjeldatud viis töötas minu jaoks paremini kui teised katsed.
Ma peaaegu sattusin segadusse kõigist erinevatest meetoditest, kõik need erinevad väikesed kausid erinevate segudega seisid kõikjal, ma alati vaatasin, milline neist areneb hästi ja milline mitte.
Näiteks kui paned jääkülma ipa kristalliseeruvale veele/pulbrile, siis saad kohe mõned valged kristallid, aga need ei ole selged ja ainult natuke, sp pead uuesti kristalliseeruma ja ülejäänud peab aurustuma, vaata viimast pilti.
Teised 3 pilti näitavad, mis juhtub rm minu sügavkülmikus, see muutub tahkeks massiks, mis sulab toatemperatuuril, aga kristalle ei teki.

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
