5-Bromo-2-methyl-3-nitropyridine (CAS# 911434-05-4)

Isingeniso

I-5-Bromo-2-methyl-3-nitropyridine iyinhlanganisela yezinto eziphilayo.

Izakhiwo: I-5-Bromo-2-methyl-3-nitropyridine iyikristalu ephuzi ukuya kuwolintshi enokunambitheka okukhethekile kwe-nitro. Iyazinzile ekamelweni lokushisa, kodwa ukubola kungase kwenzeke lapho kushisa noma kuthintana nama-asidi aqinile.

Ingasetshenziswa futhi ekuhlaziyweni kwamakhemikhali, ama-biomarker, kanye ne-organic synthesis.

Indlela yokulungiselela: Indlela yokulungiselela i-5-bromo-2-methyl-3-nitropyridine ingaba i-nitrification. Indlela evamile ukusabela ku-2-methylpyridine nge-nitric acid egxilile ukukhiqiza i-2-methyl-3-nitropyridine, bese usebenzisa i-bromine ukuze ibhekane ne-bromination reaction phambi kwe-sulfuric acid ukuze uthole umkhiqizo wokugcina.

Ulwazi lokuphepha: I-5-bromo-2-methyl-3-nitropyridine izinzile ngaphansi kwezimo zokusetshenziswa okuvamile, kodwa kusadingeka ukunaka ukusebenza okuphephile. Kuyinto evuthayo futhi ukuthintana namalangabi avulekile noma amazinga okushisa aphezulu kufanele kugwenywe. Izimpahla zokuzivikela ezifanele, njengamagilavu ​​aselabhorethri nezibuko zokuphepha, kufanele zigqokwe lapho usebenza futhi ugweme ukuthinta isikhumba namehlo. Uma uthintana ngephutha, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha ngokushesha. Imfucuza kufanele igcinwe kahle futhi ilahlwe ukuze kuvikelwe imvelo.
