Intshayelelo
I-4-Methylphenylacetone, eyaziwa ngokuba yi-4-methylphenylacetone, i-organic compound.
Nazi ezinye iimpawu ezibalulekileyo malunga ne-4-methylpropionone:
1. Imbonakalo: ulwelo olungenambala okanye ikristale emhlophe.
2. Ubuninzi: 0.993g/mLat 25°C(lit.)
5. Ukunyibilika: Inyibilika kwizinyibilikisi ze-organic ezifana ne-ethanol, i-ether kunye ne-benzene.
6. Uzinzo lokugcina: Kufuneka lugcinwe kude namadangatye avulekileyo kunye nee-oxidants, kwaye lugcinwe kwindawo eyomileyo, epholileyo kunye nengenamoya.
I-4-Methylpropiophenone inokusetyenziswa kwezinye iindawo, kuquka:
2. Ukusetyenziswa kophando: Kwi-organic synthesis, ingasetyenziselwa njenge-precursor ye-ketones okanye i-alcohol for synthesis yezinye izinto eziphilayo.
Iindlela eziqhelekileyo zokulungiselela i-4-methylpropiophenone ziquka:
1. I-Marthet reaction: I-Styrene kunye ne-carbon dioxide iphendulwa kwi-reactor ring sweep reactor ukuze ifumane i-4-methylacetophenone, kwaye ke i-4-methylacetophenone ilungiswe nge-oxidation kunye nokunciphisa.
2. I-Vilsmeier-Haack reaction: I-Phenylethanol iphendulwa nge-nitric acid kunye ne-phosphine phantsi kweemeko zokusabela kwe-alkylation ye-alkylloids ukufumana i-4-methylphenylacetone.
1. Kuphephe ukudibana nesikhumba, amehlo kunye ne-mucous membranes.
3. Kuphephe ukuphefumla umphunga okanye inkungu, kwaye unxibe iiglavu zokhuselo ezifanelekileyo, iiglasi kunye nempahla yokuzikhusela xa usebenzisa.
5. Xa ugcina kwaye uphatha, thintela ukudibanisa nezinto ezinokutsha kwaye ugcine kwisitya esingenawo umoya, kude nemithombo yokushisa kunye nomlilo ovulekileyo.
