Isingeniso
3,4 '-I-Dichloropropiophenone, ifomula yamakhemikhali i-C9H7Cl2O, iyinhlanganisela yezinto eziphilayo.
Imvelo:
3,4 '-I-Dichloropropiophenone iqinile elingenambala ukuya kokuphuzi ngokuphaphathekile elinephunga lamakhemikhali elihlukile. Ayincibiliki emanzini futhi iyancibilika kancane kuma-alcohols nama-ether.
Sebenzisa:
3,4 '-I-Dichloropropiophenone ivame ukusetshenziswa njenge-reagent ku-organic synthesis. Ingasetshenziswa ekuhlanganiseni izidakamizwa, odayi nezinye izinhlanganisela. Ingasetshenziswa futhi njengento eluhlaza yokulungiswa kwezibulala-zinambuzane kanye nama-flavour.
Indlela Yokulungiselela:
Kunezindlela ezihlukahlukene zokulungiselela i-3,4 '-Dichloropropiophenone. Indlela evamile ukuthola i-3,4′-dichlorophenyl ethanone nge-bromination noma nge-chlorination ngaphansi kwezimo ze-alkaline.
Ulwazi Lokuphepha:
3,4 '-I-Dichloropropiophenone iwubuthi futhi ukuthintana ngqo nesikhumba kanye nokuhogela umhwamuko wayo kufanele kugwenywe. Izinto zokuzivikela ezifanele, njengamagilavu okuvikela amakhemikhali nokuvikela amehlo, kufanele zigqokwe lapho zisetshenziswa noma ziphathwa. Gwema izinga lokushisa eliphezulu futhi uvule umlilo ngesikhathi sokugcina. Qiniseka ukuthi uyisebenzisa endaweni ephephile futhi engenamoya futhi uyilahle esitsheni sokulahlwa okungenangozi. Uma ukugwinya noma ukuthintana kwenzeka, funa usizo lwezokwelapha ngokushesha.
