Ubungozi Nokuphepha

Amakhodi Engozi R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile.
Incazelo Yokuphepha S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu ​​kanye nokuvikela iso/ubuso.
S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
S36 – Gqoka izingubo ezifanele zokuzivikela.

I-2,3-Dibromopyridine (CAS# 13534-89-9) isingeniso

I-2,3-dibromopyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza, nolwazi lokuphepha:
imvelo:
-2,3-dibromopyridine iqinile elingenambala ukuya kokuphuzi okuphaphathekile elinephunga elimnandi.
-Incibilika kuma-solvents ephilayo njenge-ethanol, i-dimethylformamide, ne-dichloromethane ekamelweni lokushisa, kodwa ayincibiliki emanzini.
-Le nhlanganisela izwela ukukhanya nomoya futhi kufanele igcinwe esitsheni esivaliwe kude nokukhanya.
Inhloso:
-2,3-dibromopyridine ivame ukusetshenziswa njengento ebalulekile ephakathi ekuhlanganiseni kwezinto eziphilayo.
-Ingasetshenziselwa ukufaka esikhundleni kanye nokusabela kwe-condensation ku-organic synthesis.
Indlela yokukhiqiza:
-Indlela evamile yokulungiselela i-2,3-dibromopyridine iwukuba i-bromination reaction ye-pyridine.
-Indlela evame ukusetshenziswa yokulungiselela ukushisa i-pyridine emanzini e-bromine agxilile ukuze aphendule, futhi umphumela we-2,3-dibromopyridine ukhuphuka kusuka kusixazululo sokusabela ngemva kokupholisa.
Ulwazi lokuphepha:
-2,3-dibromopyridine iyinhlanganisela ecasulayo engabangela ukucasuka kwamehlo nesikhumba lapho uthintana.
-Izimpahla zokuzivikela ezifanele njengamagilavu, izibuko, nezingubo zokuzivikela kufanele zigqokwe ngesikhathi sokusebenza.
-Gwema ukuhogela uthuli noma igesi yayo, futhi usebenze endaweni engenawo umoya.
