Hordhac
4-Methylphenylacetone, oo sidoo kale loo yaqaan 4-methylphenylacetone, waa unug dabiici ah.
Waa kuwan qaar ka mid ah guryaha muhiimka ah ee ku saabsan 4-methylpropionone:
1. Muuqashada: dareere aan midab lahayn ama crystal cad.
2. Cufnaanta: 0.993g/mLat 25°C(iftiin)
5. Solubility: Waxay ku milmaan dareerayaasha organic sida ethanol, ether iyo benzene.
6. Xasiloonida kaydinta: Waa in laga fogeeyo ololka furan iyo oksaydhiyeyaasha, laguna kaydiyaa meel qalalan, qabow oo hawo leh.
4-Methylpropiophenone waxa ay leedahay qaar ka mid ah isticmaalka meelaha qaarkood, oo ay ku jiraan:
2. Isticmaalka cilmi-baarista: Isku-dhafka dabiiciga ah, waxaa loo isticmaali karaa horudhac ah ketones ama alkolada loogu talagalay isku-darka xeryahooda kale ee organic.
Hababka caadiga ah ee diyaarinta 4-methylpropiophenone waxaa ka mid ah:
1. Dareen-celinta Marthet: Styrene iyo carbon dioxide ayaa lagu falceliyaa giraanta xaaqidda joogtada ah si loo helo 4-methylacetophenone, ka dibna 4-methylacetophenone waxaa lagu diyaariyaa oksaydheynta iyo dhimista.
2. Vilsmeier-Haack reaction: Phenylethanol waxaa lagu falceliyaa nitric acid iyo phosphine iyadoo la raacayo xaaladaha falcelinta alkylloids ee alkylloids si loo helo 4-methylphenylacetone.
1. Ka fogow taabashada maqaarka, indhaha iyo xuubabka.
3. Iska ilaali in aad neefsato uumiga ama ceeryaamo, oo xidho galoofyada ilaalinta, muraayadaha indhaha, iyo dharka ilaalinta marka aad isticmaalayso.
5. Marka aad kaydinayso iyo marka aad wax ka qabanayso, iska ilaali in aad la taabato walxaha guban oo ku kaydi weel aan hawadu karin, kana fog meelaha kulaylka ah iyo ololka furan.
