Želim izdelati 4-mmc, vendar želim, da bi bil čim bolj čist, tako da ko bom izdelal svoj 4-MMC, ki bo zagotovo imel nečistoče, kako bi ga očistil in ali rekristaliziral. Ne bi želel vzeti ali prodati ničesar, kar ni vrhunske kakovosti, da bi bil varen. Hvala.

O tem obstajajo članki, za začetek si jih preberite, prav tako pa tudi razpravo pod njimi.

Izperite ga z acetonom in reciklirajte :)

Kakšna bi bila najučinkovitejša tehnika za to? Videl sem videoposnetke, v katerih je bil aceton prelit čez prah/ kristal na Buchnerjevem filtru in takoj filtriran. Videl sem tudi, da je nekdo v neki razpravi predlagal, naj se prašek 4-MMC z acetonom premeša v kozarcu/kuhalnici, da se nečistoče pred filtriranjem bolje raztopijo. Ali bi bilo stresanje prahu z acetonom v zaprtem kozarcu najboljši način kot najbolj agresivna oblika mešanja?

Ali naj v Buchnerjev filter pred vsakim vakuumiranjem nalijem aceton in ga premešam, da se nečistoče lažje raztopijo? Prav tako mora biti aceton hladen, če je, kako hladen, v zamrzovalniku ali hladnem hladilniku? Hvala.

Po vsem tem nameravam opraviti tudi rekristalizacijo, da bi imel čim bolj čist izdelek, vendar želim pred tem zaradi varnosti odstraniti večino nečistoč.

Everything depends on situation.
Most important thing is a plan for synthesis, correct reagents and solvents will make your syntheis successfull if you do it carefully and decent.
Smooth and planned work will always lead to good output. If some mistake happens it should be instantly taken action to get back to course as close as it can.
Usually you can not fix such impurity. To get rid of shit you need to add another shit :)
Most important is to have clean product for crystalisation so it will show its potential after performing this procedure :)
