Reakcijska shema:
6RfIzHmQtn


Sinteza:
V 200-litrski reaktor smo dodali 25 litrov acetonitrila in 5 litrov vode.
2. V reaktor smo dodali 1000 g a-metilstirena, 5202 g kalijevega peroksimonosulfata in 127 g natrijevega jodida.
2. Reakcijsko zmes smo 24 ur mešali pri sobni temperaturi.
3. Po tem času smo reakcijsko zmes razredčili s 85 litri vode in jo ekstrahirali s 30 litri DCM.
4. Vodno plast smo odstranili, ekstrakt DCM smo odstranili, da smo dobili rumeno olje.
5. Izplen fenilacetona je približno 1000 g.

Na tem spletnem mestu je veliko zavajanj, ko gre za specifično kemijo. Toda Oxone - ta izdelek je namenjen za bazene, prodaja se v ustreznih trgovinah. AMS in NaI sta prav tako na voljo. Acetonitril se lahko v nekaterih primerih nadomesti. V kateri državi ste? Lahko napišete PM za več podrobnosti o sintezi.

1) Kakšna je vloga acetonitrila v tej reakciji? Je samo topilo?
2) Zakaj je potrebna tako velika količina acetonitrila v primerjavi z drugimi ingridienti?
