Intangiriro
2-Bromo-5-chloro-3-picoline ni ifumbire mvaruganda hamwe na formula ya chimique C7H6BrClN. Ibikurikira nubusobanuro bwimiterere, imikoreshereze, imyiteguro namakuru yumutekano yikigo:
Kamere:
-Ibigaragara: 2-Bromo-5-chloro-3-picoline ni amazi adafite ibara cyangwa umuhondo muto.
-Gukemuka: Gukemuka mumashanyarazi menshi, nka Ethanol, dimethylformamide na chloroform.
-Gushonga ingingo hamwe no guteka: Ingingo yo gushonga yikigo igera kuri -35 ° C, naho aho itetse ni 205-210 ° C.
Koresha:
- 2-Bromo-5-chloro-3-picoline irashobora gukoreshwa nkibikoresho bitangira cyangwa hagati muguhuza ibinyabuzima, kandi irashobora gukoreshwa muguhuza ibindi bintu, nka pesticide nibiyobyabwenge.
-Bikoreshwa kandi cyane muburyo bwoguhuza, biphenili polychlorine, biphenili polybromine na pigment.
Uburyo bwo Gutegura:
- 2-Bromo-5-chloro-3-picoline isanzwe itegurwa na bromination na chlorine ya 3-picoline. Ubwa mbere, 3-methylpyridine isubizwa hamwe na hydrogen bromide kugirango ibone 2-bromo-5-methylpyridine, hanyuma ibicuruzwa bigakorwa hamwe na catalizike ya chloride kugirango ibone ibicuruzwa bigenewe.
Amakuru yumutekano:
- 2-Bromo-5-chloro-3-picoline muri rusange ntabwo itera ingaruka mbi mubihe bisanzwe bikoreshwa. Ariko, birashobora kurakaza amaso, uruhu hamwe nubuhumekero, bityo rero hagomba kwitonderwa kugirango wirinde guhura.
-Koresha ibikoresho bikingira birinda, nka gants ya chimique, goggles hamwe ningabo zo mumaso.
-Imikorere myiza ya laboratoire igomba gukurikizwa mugihe cyo kuyikoresha kandi hagomba kubaho umwuka mwiza.
-Irinde guhura na okiside ikomeye na acide ikomeye mugihe cyo gufata no kubika.
