Isingeniso
I-4-Methylphenylacetone, eyaziwa nangokuthi i-4-methylphenylacetone, iyinhlanganisela yezinto eziphilayo.
Nazi ezinye izici ezibalulekile mayelana ne-4-methylpropionone:
1. Ukubukeka: uketshezi olungenambala noma ikristalu emhlophe.
2. Ukuminyana: 0.993g/mLat 25°C(lit.)
5. Ukunyibilika: Kuncibilika kuzincibilikisi zemvelo njenge-ethanol, i-ether ne-benzene.
6. Ukuzinza kwesitoreji: Kufanele kugcinwe kude namalangabi avulekile nama-oxidants, futhi kugcinwe endaweni eyomile, epholile futhi engenamoya.
I-4-Methylpropiophenone inokusetshenziswa kwezinye izindawo, okuhlanganisa:
2. Ukusetshenziswa kocwaningo: Ku-organic synthesis, kungasetshenziswa njengesandulela sama-ketones noma ama-alcohol ekuhlanganiseni kwamanye ama-organic compounds.
Izindlela ezijwayelekile zokulungiselela i-4-methylpropiophenone zifaka:
1. Ukusabela kwe-Marthet: I-styrene ne-carbon dioxide isabela ku-reactor yokushanela indandatho eqhubekayo ukuze zithole i-4-methylacetophenone, bese i-4-methylacetophenone ilungiswa nge-oxidation nokunciphisa.
2. Ukusabela kwe-Vilsmeier-Haack: I-Phenylethanol isabela nge-nitric acid ne-phosphine ngaphansi kwezimo zokusabela ze-alkylation ye-alkylloids ukuze ithole i-4-methylphenylacetone.
1. Gwema ukuthinta isikhumba, amehlo nolwelwesi lwamafinyila.
3. Gwema ukuhogela inkungu noma inkungu, futhi gqoka amagilavu okuzivikela afanele, izibuko, nezingubo zokuzivikela lapho usebenzisa.
5. Lapho ugcina futhi uphatha, gwema ukuthintana nezinto ezivuthayo futhi ugcine esitsheni esingangeni moya, kude nemithombo yokushisa namalangabi avulekile.
