3 4-DIBROMOPYRIDINE (CAS# 13534-90-2)
Ubungozi Nokuphepha
| Izimpawu Eziyingozi | Xi - Irritant |
| Amakhodi Engozi | 36/37/38 - Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36 – Gqoka izingubo ezifanele zokuzivikela. |
| I-Hazard Class | I-IRRITANT |
Isingeniso
I-3,4-Dibromopyridine (i-CAS# 13534-90-2) iyinhlanganisela ye-organic ene-chemical formula C5H3Br2N. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha:
Imvelo:
I-3,4-Dibromopyridine iqinile elingenambala ukuya kokuphuzi okuphaphathekile elinephunga elimnandi elihlukile. Incibilika kuma-organic solvents njenge-ethanol, i-chloroform ne-dimethylformamide ekushiseni okuvamile. Ibonisa izinga eliphezulu lokuncibilika nokubilisa.
Sebenzisa:
I-3,4-Dibromopyridine inezinhlelo zokusebenza ezibalulekile ku-organic synthesis. Ingasetshenziswa njenge-catalyst noma i-reaction intermediate ukubamba iqhaza ekuphenduleni okuhlukahlukene kwe-organic, njengokusabela kokuhlangana kwe-Suzuki, ukusabela kokwakheka kwebhondi ye-C-C, njll. Ngaphezu kwalokho, ingasetshenziswa futhi ekulungiseni izidakamizwa, odayi kanye ama-polymer compounds.
Indlela Yokulungiselela:
Indlela yokulungiselela i-3,4-dibromopyridine ilula. Indlela eyodwa evamile iwukusabela i-pyridine nge-bromine ngaphansi kwezimo ezifanele zokusabela ukukhiqiza i-3,4-dibromopyridine. Ukusabela kungenziwa ekushiseni okujwayelekile noma ngaphansi kokushisa.
Ulwazi Lokuphepha:
Ukunakekelwa kokuphepha kuyadingeka lapho uphatha i-3,4-dibromopyridine. Kungase kubangele ukucasuka noma ukulimala kwamehlo, isikhumba, kanye nesistimu yokuphefumula. Ngakho-ke, izinto zokuzivikela ezifanele njengezingilazi zokuphepha, amagilavu nezingubo zokuzivikela kufanele zigqokwe ngesikhathi sokusebenza. Gwema ukuhogela umhwamuko wayo, futhi kuhle ukuyisebenzela endaweni enomoya omuhle. Lapho ulahla imfucuza, bheka imithetho yendawo futhi uyilahle ngendlela efanele. Uma unezinkinga zempilo noma ukuphepha, kufanele uphendukele kuchwepheshe ngokushesha.
