Pozdravljeni
Prosim, če mi lahko kdo pomaga pri sintezi 4-cmc. Na en mol bromoketona bom uporabil 4 mole metilamina (40-odstotna raztopina v vodi). Kot topilo bom uporabil dcm ali toluen. Kateri čas je najboljši, katero topilo je boljše in kakšna temperatura mora biti idealna. Ne želim uporabiti benzena, ker je zelo strupen.

Torej, če ga bom kuhala 2 uri pri 40 °C, bom izdelek dobila v dobrih številkah ?

To, kar je povedal patton, je pravilno.

Ena nepolarna in ena bipolarna aprotična. npr:

Toluen + NMP
DCM + DMSO

Bistvo je, da maso homogeniziramo do enofaznosti, zaradi česar poteka veliko hitreje.
Lahko pa reagirate v samo DCM čez noč (8 ur)

Tako NMP kot DMSO sta topili z visokim vreliščem (nad 200*C), ki se mešata z vodo. DCM vre zelo nizko @-40*C, toluen pa vre @110*C. Ključno je mešanje.
