5-Bromo-2-3-dichloropyridine (CAS#97966-00-2)
Ubungozi Nokuphepha
| Amakhodi Engozi | R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R41 – Ingozi yokulimala okubi emehlweni R37/38 – Ukucasula uhlelo lokuphefumula kanye nesikhumba. R25 – Kunobuthi uma ugwinywe |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) S39 – Gqoka ukuvikela iso / ubuso. |
Isingeniso
-Ukubukeka: Ayinambala ikristale ephuzi noma i-crystalline powder
-Indawo yokuncibilika: 62-65°C
-Indawo yokubilisa: 248°C
-Ukuminyana: 1.88g/cm³
-ayincibiliki emanzini, ancibilika kuzincibilikisi zemvelo (njenge-chloroform, i-methanol, i-ether, njll.)
Sebenzisa:
- I-5-bromo-2,3-dichloropyridine iyingxenye ebalulekile ekuhlanganiseni kwe-organic.
-Ingasetshenziselwa ukulungisa ama-compounds abhalwe ukuthi aqukethe ama-isotopes e-carbon radioactive carbon.
Indlela Yokulungiselela:
Indlela yokulungiselela ye--5-bromo-2,3-dichloropyridine ivame ukutholakala ngokusabela kwe-bromination esikhundleni se-2,3-dichloro-5-nitropyridine. Indlela eqondile iwukuba uqale usabele i-2,3-dichloro-5-nitropyridine nge-phosphorus trichloride, bese wenza ukusabela kokufakwa esikhundleni kwe-bromination nge-bromine.
Ulwazi Lokuphepha:
- I-5-bromo-2,3-dichloropyridine iyinhlanganisela yezinto eziphilayo futhi idinga ukulandela izinqubo zokusebenza eziphephile lapho iphathwa futhi isebenzisa.
-Kungase kucasule amehlo, isikhumba kanye nesimiso sokuphefumula, ngakho gqoka izibuko, amagilavu kanye ne-mask.
-Sicela uyigcine kahle, kude nomlilo, ukushisa kanye ne-oxidant, futhi ugweme ukuthintana ne-asidi eqinile ne-alkali.
-Uma uhogela umoya noma ukuthintana ngephutha, hlanza indawo ethintekile ngokushesha futhi ufune usizo lwezokwelapha.
