Mawu Oyamba
4-Methylphenylacetone, yomwe imadziwikanso kuti 4-methylphenylacetone, ndi organic compound.
Nazi zina zofunika zokhudzana ndi 4-methylpropionone:
1. Maonekedwe: madzi opanda mtundu kapena kristalo woyera.
2. Kachulukidwe: 0.993g/mLat 25°C(lit.)
5. Kusungunuka: Kusungunuka mu zosungunulira za organic monga ethanol, etha ndi benzene.
6. Kukhazikika kwa kasungidwe: Iyenera kusungidwa kutali ndi malawi otseguka ndi oxidant, ndikusungidwa pamalo owuma, ozizira komanso mpweya wabwino.
4-Methylpropiophenone ili ndi ntchito zina m'malo ena, kuphatikiza:
2. Kugwiritsa ntchito kafukufuku: Mu kaphatikizidwe ka organic, itha kugwiritsidwa ntchito ngati kalambulabwalo wa ma ketoni kapena ma alcohols popanga zinthu zina.
Njira zodziwika zopangira 4-methylpropiophenone ndi izi:
1. Marthet reaction: Styrene ndi carbon dioxide amachitidwa muzitsulo zopitirirabe kuti apeze 4-methylacetophenone, ndiyeno 4-methylacetophenone imakonzedwa ndi okosijeni ndi kuchepetsa.
2. Vilsmeier-Haack reaction: Phenylethanol imachitidwa ndi nitric acid ndi phosphine pansi pa zochitika za alkylation za alkylloids kuti apeze 4-methylphenylacetone.
1. Pewani kukhudza khungu, maso ndi mucous nembanemba.
3. Pewani kupuma mpweya kapena nkhungu, ndipo valani magolovesi oteteza, magalasi, ndi zovala zodzitetezera pamene mukugwiritsa ntchito.
5. Posunga ndikugwira, pewani kukhudzana ndi zinthu zoyaka moto ndipo sungani mu chidebe chotchinga mpweya, kutali ndi magwero a kutentha ndi malawi otseguka.
