3-Bromo-2 6-dichloropyridine (CAS# 866755-20-6) Isingeniso
I-3-Bromo-2,6-dichloropyridine iyinhlanganisela ye-organic enefomula yamakhemikhali ethi C5H2BrCl2N. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
- I-3-Bromo-2,6-dichloropyridine iqinile ngesimo sekristalu esimhlophe ukuya kokuphuzi.
-Izinga lokuncibilika kwalo lilinganiselwa ku-60-62 degrees Celsius, kanti izinga lokubila kwalo liba ngu-240 degrees Celsius.
- I-3-Bromo-2,6-dichloropyridine ayincibiliki emanzini, kodwa incibilika kuma-organic solvents njenge-ethanol ne-dimethylformamide (DMF).
Sebenzisa:
- I-3-Bromo-2,6-dichloropyridine iyinhlangano ebalulekile ye-organic synthesis ephakathi, esetshenziswa kabanzi ezimbonini zokubulala izinambuzane, ezemithi kanye namakhemikhali.
-Ingasetshenziswa njengezinto ezingavuthiwe zokuhlanganiswa kwezinye izinhlanganisela, njengezibulala-zinambuzane, izidakamizwa ezilwa nomdlavuza kanye nodayi be-fluorescent.
Indlela Yokulungiselela:
Ukulungiswa kwe--3-Bromo-2,6-dichloropyridine kungatholakala ngokuphendula i-2,6-dichloropyridine nge-bromine.
-Izimo zokusabela zidinga ukushisa futhi zenziwa ku-solvent efanelekile njenge-acetone noma i-dimethylbenzamide.
Ulwazi Lokuphepha:
- I-3-Bromo-2,6-dichloropyridine kufanele igcinwe ngendlela evimbela uthuli futhi igcinwe endaweni epholile, eyomile, kude nomlilo kanye nezinga lokushisa eliphezulu.
-Gqoka izinto zokuzivikela ezifanele njengezibuko, amagilavu nezingubo zokuzivikela uma zisetshenziswa.
-Gwema ukuthinta isikhumba, amehlo kanye nomgudu wokuphefumula. Uma kwenzeka ukuthintana ngephutha, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.
-Lapho usebenzisa futhi ugcina, qaphela ukuhambisana nezinqubo ezifanele zokusebenza zokuphepha ukuze uqinisekise ukuphepha komuntu siqu kanye nokuphepha kwemvelo.
