Isingeniso
I-2,5-Dichloro-3-nitropyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-2,5-Dichloro-3-nitropyridine iyikristalu eliphuzi elikhanyayo elingenambala.
- Ukunyibilika: Incibilika kuzincibilikisi zemvelo njenge-ethanol, i-dimethyl ether ne-chloroform, kodwa ayincibiliki kancane emanzini.
- Ukuzinza: Inhlanganisela izinzile ekamelweni lokushisa, kodwa iqhuma emazingeni okushisa aphezulu noma ihlangene nama-oxidizing agents aqinile.
Sebenzisa:
- Izibulala-zinambuzane: Ingasetshenziswa njengesibulala-zinambuzane futhi inomphumela omuhle wokulawula ezinye izinambuzane.
Indlela:
Indlela yokuhlanganisa ye-2,5-dichloro-3-nitropyridine ngokuvamile ihlanganisa ukusabela kwe-nitrification nokusabela kwe-chlorination. Phakathi kwazo, indlela yendabuko yokuhlanganisa i-nitrate 2,5-dichloropyridine ne-nitric acid phambi kwe-sulfuric acid. Enye indlela iwukusabela i-2-nitro-5-chloropyridine nge-acidic copper bromide ukukhiqiza i-2,5-dichloro-3-nitropyridine.
Ulwazi Lokuphepha:
- I-2,5-Dichloro-3-nitropyridine iyinhlanganisela yemvelo edinga ukuphathwa ngokucophelela ukuze inqande ukuthintana nesikhumba, amehlo, kanye nesistimu yokuphefumula.
- Gqoka okokuvikela okufanele, okuhlanganisa izingubo zamehlo ezivikelayo, amagilavu, nezihlangu zobuso, lapho usebenza.
- Ngesikhathi sokusebenza, gwema ukuhogela amagesi, inkungu noma umhwamuko futhi ugcine umoya omuhle.
- Uma uthinta isikhumba noma amehlo, hlambulula ngokushesha ngamanzi amaningi futhi uthintane nodokotela.
- Lapho ugcina, i-2,5-dichloro-3-nitropyridine kufanele igcinwe endaweni eyomile, epholile, enomoya omuhle, kude nokuvutha kanye nama-oxidants.
