Isingeniso
I-5-bromo-3-cyanopyridine iyinhlanganisela ye-organic ene-chemical formula C6H3BrN2. Kuyikristalu emhlophe kuya kokuphuzi, encibilika kwezinye izinyibilikisi eziphilayo njenge-ethanol ne-dimethyl sulfoxide. Okulandelayo incazelo eningiliziwe yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha lwe-5-bromo-3-cyanopyridine:
Imvelo:
-Ukubukeka: Amakristalu amhlophe kuya kokuphuzi
-Indawo yokuncibilika: cishe ku-89-93°C
-Indawo yokubilisa: mayelana ne-290-305°C
-Ukuminyana: Cishe ngu-1.64 g/mL
Isisindo samangqamuzana: 174.01g/mol
Sebenzisa:
I-5-bromo-3-cyanopyridine ivame ukusetshenziswa njengendawo ephakathi ku-organic synthesis, futhi inezinhlelo zokusebenza ezibalulekile emkhakheni wokuhlanganiswa kwezidakamizwa, ukuhlanganiswa kwezibulala-zinambuzane kanye nokuhlanganiswa kodayi.
Izinhlelo zokusebenza ezithize zifaka:
-Emkhakheni wezokwelapha, ingasetshenziswa ukuhlanganisa izidakamizwa ezilwa ne-tumor, izidakamizwa ezilwa namagciwane kanye nezidakamizwa ezilwa namagciwane.
-Emkhakheni wezibulala-zinambuzane, ingasetshenziswa kuma-synthetic pesticides nama-herbicides.
-Emkhakheni wodayi, ingasetshenziswa ukuhlanganisa odayi bemvelo.
Indlela Yokulungiselela:
Indlela yokulungiselela i-5-bromo-3-cyanopyridine ingenziwa ngezinyathelo ezilandelayo:
1. I-3-cyanopyridine ihlangana ne-hydrobromic acid ngaphansi kwezimo ze-alkaline ukuze ikhiqize i-5-bromo-3-cyanopyridine.
Ulwazi Lokuphepha:
Izinyathelo zokuphepha ezilandelayo kufanele zithathwe lapho usebenzisa i-5-bromo-3-cyanopyridine:
-Kuyinhlanganisela yezinto eziphilayo ezicasulayo. Gwema ukuhogela uthuli noma ukuthinta isikhumba namehlo.
-Ekusetshenzisweni nasekugcinweni, kufanele kulandele izinqubo zokuphepha, gqoka izinto zokuzivikela, njengamagilavu nezibuko zokuphepha.
-Gwema ukuxubana noma ukuthintana nezinto ezifana nama-oxidants aqinile nama-asidi aqinile ukuze uvimbele ukusabela okuyingozi.
-Gcina endaweni engenawo umoya kude namalangabi avulekile nemithombo yokushisa.
-Uma uhogeliwe noma uthinta isikhumba namehlo, geza ngokushesha ngamanzi. Funa usizo lwezokwelapha uma kudingeka.
Uma kubhekwa izinkinga zokuphepha, ukusetshenziswa nokuphathwa kwe-5-bromo-3-cyanopyridine kufanele kulandele izinqubo ezifanele zaselabhorethri futhi kuhambisane nemithetho yokuphepha efanele.
