Min 3-CMC-syntese

Det er fantastisk.

Hvorfor tror du, at fryseren gav dig mærkelige resultater under krystalliseringen?

Hvor godt tror du, at denne metode kan skaleres op?

På grund af vandet, når det fryser, hvor skal krystallerne så komme fra?
Et normalt køleskab virker måske, men jeg har min mad derinde og vil ikke rengøre det hver gang.
Jeg prøvede virkelig mange måder at nå frem til det endelige produkt på og spildte også en masse opløsningsmidler og 2b3c, men den måde, jeg beskrev, fungerede bedre for mig end de andre forsøg.
Jeg blev næsten forvirret af alle de forskellige metoder, alle de forskellige små skåle med forskellige blandinger stod rundt omkring, og jeg holdt altid øje med, hvilken der udviklede sig godt, og hvilken der ikke gjorde.
For eksempel, når du kommer iskold ipa i krystalliseringsvandet/pulveret, får du nogle hvide krystaller med det samme, men de er ikke klare og kun en lille smule, så du skal krystallisere igen, og resten skal fordampe, se sidste billede.
De 3 andre billeder viser, hvad der sker med rm i min fryser, det bliver en fast masse, som smelter ved stuetemperatur, men ingen krystaller.

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
