Isingeniso
I-4-Hydroxy-3-methylacetophenone, eyaziwa nangokuthi i-4-hydro-3-methyl-1-phenyl-2-butanone, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
I-4-Hydroxy-3-methylacetophenone iwuketshezi olungenambala noma oluphuzi olunephunga elikhethekile. Kuyinhlanganisela ye-polar encibilika kuma-alcohol, ama-ether, ama-ketone, nama-ester solvents.
Sebenzisa:
Indlela:
Kunezindlela eziningi zokulungiselela i-4-hydroxy-3-methylacetophenone, futhi enye yezindlela ezivamile itholakala ngokusabela kwe-oxidation yama-carbonyl compounds. Izinyathelo ezithile zihlanganisa ukuphendula i-3-methylacetophenone nge-iodine noma i-sodium hydroxide ukuze kutholwe iodozolate ehambisanayo noma i-hydroxyl, ebese iguqulelwa ku-4-hydroxy-3-methylacetophenone ngokusabela kokunciphisa.
Ulwazi Lokuphepha:
I-4-Hydroxy-3-methylacetophenone ibhekwa njengephephile uma kuqhathaniswa nezinhlelo zokusebenza ezijwayelekile. Njengenhlanganisela yezinto eziphilayo, isenazo ezinye izingozi ezingaba khona. Ukuthinta isikhumba kanye nokuhogela umhwamuko waso kungase kubangele ukucasuka futhi kungase kubangele ukungezwani komzimba. Lapho uphatha le nhlanganisela, kufanele kuqashelwe ukusebenzisa izinto zokuzivikela (njengamagilavu kanye nezingubo zamehlo ezivikelayo) futhi uqinisekise ukungena komoya okuhle. Esimeni lapho uthintana ngengozi noma uhogele umoya, into leyo kufanele igezwe noma isuswe ngokushesha futhi kufunwe nokwelashwa. Lapho ugcina futhi uphatha, sicela ubheke izindlela zokuphepha ezifanele ukugwema noma yiziphi izingozi.
