3-Bromo-2 6-dichloropyridine (CAS# 866755-20-6) Intshayelelo
I-3-Bromo-2,6-dichloropyridine yi-organic compound kunye ne-chemical formula C5H2BrCl2N. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Indalo:
- I-3-Bromo-2,6-dichloropyridine iqinile kunye nefom yecrystalline emhlophe ukuya kumthubi.
-Indawo yokunyibilika kwayo imalunga ne 60-62 degrees celcius, kwaye iqondo lokubila kwayo limalunga nama 240 degrees celcius.
- I-3-Bromo-2,6-dichloropyridine ayinyibiliki emanzini, kodwa i-soluble kwii-solvents eziphilayo ezifana ne-ethanol kunye ne-dimethylformamide (DMF).
Sebenzisa:
- I-3-Bromo-2,6-dichloropyridine yinto ebalulekileyo ye-organic synthesis intermediate, esetyenziswa ngokubanzi kwi-pesticide, amayeza kunye namashishini amachiza.
-Ingasetyenziselwa njengento ekrwada yokwenziwa kwezinye iikhompawundi, ezifana ne-pesticides, iziyobisi ezichasayo zomhlaza kunye ne-fluorescent dyes.
Indlela yokulungiselela:
Ukulungiswa kwe-3-Bromo-2,6-dichloropyridine inokufumaneka ngokuphendula i-2,6-dichloropyridine kunye ne-bromine.
-Iimeko zokusabela zifuna ukufudumeza kwaye ziqhutyelwa kwi-solvent efanelekileyo njenge-acetone okanye i-dimethylbenzamide.
Ulwazi ngoKhuseleko:
- I-3-Bromo-2,6-dichloropyridine kufuneka igcinwe kwifomu yobungqina bothuli kwaye igcinwe kwindawo epholileyo, eyomileyo, kude nomlilo kunye nokushisa okuphezulu.
-Nxiba izixhobo ezifanelekileyo zokuzikhusela njengeeglavu, iiglavu kunye nempahla yokuzikhusela xa usetyenziswa.
-Kuphephe ukudibana nolusu, amehlo kunye nomgudu wokuphefumla. Kwimeko yoqhagamshelwano ngengozi, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune uncedo lwezonyango.
-Xa usebenzisa kwaye ugcina, qaphela ukuthobela iinkqubo ezifanelekileyo zokusebenza zokhuseleko ukuqinisekisa ukhuseleko lomntu kunye nokhuseleko lokusingqongileyo.
