Ma tahan teha 4-mmc, kuid ma tahan, et see oleks võimalikult puhas, nii et kui ma teen oma 4-MMC, mis kindlasti sisaldab lisandeid, kuidas ma läheksin selle puhastamiseks ja või ümberkristalliseerimiseks. Ma ei tahaks võtta või müüa midagi, mis ei ole tippkvaliteediga, lihtsalt ohutuse tagamiseks. Tänan teid.

Selle kohta on artikleid, te peaksite alustuseks lugema neid ja nende all olevat arutelu.

Peske seda atsetooniga ja kristalliseerige ümber :)

Mis oleks selleks kõige tõhusam tehnika? Olen näinud videoid, kus atsetoon valati Buchneri filtril oleva pulbri/kristalli üle ja filtreeriti kohe ära. Olen ka näinud, et keegi on ühes arutelus soovitanud segada 4-MMC pulbrit atsetooniga purki/ keeduklaasi, et lisandeid enne filtreerimist paremini lahustada. Kas pulbri raputamine atsetooniga suletud purgis oleks kõige agressiivsem segamise viis?

Buchneri filtrisse peaksin enne iga vaakumi valama atsetooni ja segama seda, et aidata lisandeid lahustada? Samuti peaks atsetoon olema külm, kui jah, siis kui külmkapis või külmkapis külm? Tänan teid

Samuti kavatsen pärast kõike seda teha ümberkristalliseerimise, et saada võimalikult puhas toode, kuid tahan enne seda kindluse mõttes enamiku lisandeid välja saada.

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 :)
