Isingeniso
I-3-Chloro-4-methylpyridine iyinhlanganisela yezinto eziphilayo. Izici zayo zimi kanje:
1. Ukubukeka:3-chloro-4-methylpyridineiwuketshezi olungenambala ukuya kokuphuzi ngokukhanyayo.
2. Ukuminyana: 1.119 g/cm³
4. Ukunyibilika: I-3-chloro-4-methylpyridine iyancibilika kuma-solvents amaningi e-organic futhi ayincibiliki emanzini.
Ukusetshenziswa okuyinhloko kwe-3-chloro-4-methylpyridine imi kanje:
1. Ukuhlanganiswa kwezingxube zensimbi yenguquko: Kuyindawo ebalulekile ephakathi esetshenziswa kukhemistri yokuxhumanisa ukuhlanganiswa kwama-amino alcohols, ama-amino alkates, nezinye izinhlanganisela ze-nitrogen heterocyclic.
2. Izibulala-zinambuzane ezimaphakathi: I-3-chloro-4-methylpyridine ingasetshenziswa njengendawo ephakathi kwamanye ama-insecticide nama-herbicides.
Indlela yokulungiselela i-3-chloro-4-methylpyridine ngokuvamile ihlanganisa lezi zinyathelo ezilandelayo:
1. Ukusabela kwe-nitroation ye-pyridine: i-pyridine isabela nge-nitric acid egxilile kanye ne-sulfuric acid ukuze ithole i-3-nitropyridine.
2. Ukusabela kokunciphisa: I-3-nitropyridine isabela ngokweqile kwe-sulfoxide kanye ne-ejenti yokunciphisa (njenge-zinc powder) ukuthola i-3-aminopyridine.
3. Ukusabela kwe-chlorine: I-3-aminopyridine isabela nge-thionyl chloride ukuze ithole i-3-chloro-4-methylpyridine.
Imininingwane yokuphepha efanele ye-3-chloro-4-methylpyridine imi kanje:
1. Ukuzwela: Kungase kube nokungezwani komzimba kubantu abathile.
2. Ukucasuka: Kungase kube nomthelela ocasulayo emehlweni, ohlelweni lokuphefumula nasesikhumbeni.
3. Ubuthi: Buyingozi empilweni yomuntu futhi kufanele ilandele izinqubo ezifanele zokusebenza zokuphepha.
4. Isitoreji: Kufanele sigcinwe esitsheni esingangenisi umoya, kude nendawo evuthayo nama-oxidants, futhi kude nokuthintana nomoya.
Uma usebenzisa i-3-chloro-4-methylpyridine, landela izimiso zokuphepha ezifanele njengokugqoka izingubo zamehlo ezivikelayo, amagilavu nezingubo zokuzivikela, futhi uqinisekise ukuthi isetshenziswa endaweni enomoya omuhle. Esimeni lapho uthintana ngephutha noma uhogele umoya, funa usizo lwezokwelapha ngokushesha futhi ubonise Iphepha Lokwaziswa Lokuphepha lomkhiqizo kudokotela wakho.
