Isingeniso
I-5,6-Dichloronicotinic acid iyinhlanganisela yezinto eziphilayo. Okulandelayo incazelo eningiliziwe yemvelo yayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-5,6-Dichloronicotinic acid ayinambala kuya kumakristalu aphuzi akhanyayo noma i-crystalline powder.
- Ukunyibilika: kuncibilika kuma-alcohols nama-ether, kuncibilika kancane emanzini.
Sebenzisa:
- I-5,6-Dichloronicotinic acid ivame ukusetshenziswa njenge-reagent yamakhemikhali njenge-oxidant, i-ejenti yokunciphisa kanye ne-catalyst ekuphenduleni kwe-organic synthesis.
Indlela:
- I-5,6-dichloronicotinic acid ngokuvamile ingalungiswa ngokuncishiswa kwe-p-nitrophenol. I-Nitrophenol iphathwa nge-nitrous acid ukukhiqiza i-5,6-dinitrophenol. Khona-ke, i-5,6-dinitrophenol iyancipha ibe yi-5,6-dichloronicotinic acid isebenzisa i-chlorine noma i-nitroreducing agents.
Ulwazi Lokuphepha:
- Uthuli noma amakristalu e-5,6-dichloronicotinic acid anomthelela ocasulayo futhi angabangela ukucasuka emehlweni, isikhumba kanye nendlela yokuphefumula.
- Gqoka izinto zokuzivikela ezifanele njengezingubo zamehlo ezivikelayo, amagilavu kanye nezinsimbi zokuphefumula lapho usebenza.
- Gwema ukuhogela uthuli futhi ugweme ukuthintana kwesikhumba.
- Ngesikhathi sokugcina nokuphatha, gwema ukuthintana nama-oxidizing aqinile noma izinto ezivuthayo.
- Esimeni sokuchayeka ngengozi ku-5,6-dichloronicotin, hlambulula indawo ethintekile ngokushesha ngamanzi amaningi futhi ufune izeluleko zezokwelapha.
