Umngcipheko kunye noKhuseleko

Iikhowudi zoMngcipheko R36/37/38 – Ukucaphuka kwamehlo, inkqubo yokuphefumla kunye nolusu.
I-R41 – Umngcipheko womonakalo omkhulu emehlweni
I-R37/38 – Iyacaphukisa inkqubo yokuphefumla kunye nolusu.
I-R25 – Inetyhefu xa iginyiwe
Inkcazelo yoKhuseleko S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango.
S45 - Kwimeko yengozi okanye ukuba uziva ungaphilanga, funa iingcebiso zonyango ngokukhawuleza (bonisa ileyibhile nanini na kunokwenzeka.)
S39 –Nxiba ukhuseleko lwamehlo / ubuso.

Intshayelelo

I-5-bromo-2,3-dichloropyridine i-organic compound kunye ne-chemical formula C5H2BrCl2N. Oku kulandelayo yinkcazo yeepropati, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko lwale khompawundi:

Indalo:
-Inkangeleko: Ayinambala ukuya kwikristale etyheli okanye umgubo wekristale
-Indawo yokunyibilika: 62-65°C
-Indawo yokubila: 248°C
-Ubuninzi: 1.88g/cm³
-i-insoluble emanzini, i-soluble kwii-solvents eziphilayo (ezifana ne-chloroform, i-methanol, i-ether, njl.)

Sebenzisa:
- I-5-bromo-2,3-dichloropyridine yinto ebalulekileyo ephakathi kwi-organic synthesis.
-Ingasetyenziselwa ukulungiselela iikhompawundi ezinombhalo eziqulethe i-gaseous radioactive carbon isotopes.

Indlela yokulungiselela:
Indlela yokulungiselela ye-5-bromo-2,3-dichloropyridine idla ngokufunyanwa ngokusabela kwe-bromination substitution ye-2,3-dichloro-5-nitropyridine. Indlela ethile kukuqala ukusabela kwi-2,3-dichloro-5-nitropyridine kunye ne-phosphorus trichloride, kwaye emva koko iqhube i-bromination substitution reaction kunye ne-bromine.

Ulwazi ngoKhuseleko:
- I-5-bromo-2,3-dichloropyridine i-organic compound kwaye idinga ukulandela iinkqubo zokusebenza ezikhuselekileyo xa uphatha kwaye usebenzisa.
-Inokucaphukisa amehlo, ulusu kunye nenkqubo yokuphefumula, ngoko gqoka izibuko, iiglavu kunye nemaski.
-Nceda uyigcine ngokufanelekileyo, kude nomlilo, ukushisa kunye ne-oxidant, kwaye ugweme ukudibanisa ne-asidi eqinile kunye ne-alkali.
-Kwimeko yokuphefumla okanye ukudibana ngengozi, hlambulula indawo echaphazelekayo ngokukhawuleza kwaye ufune uncedo lwezonyango.
