Intshayelelo
I-2-Methyl-4-bromopyridine i-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-2-methyl-4-bromopyridine:
Umgangatho:
- 2-Methyl-4-bromopyridine yinto eqinileyo engenambala ukuya kumthubi.
- 2-Methyl-4-bromopyridine phantse ayinyibiliki emanzini kodwa i-soluble kwi-organic solvents.
Sebenzisa:
- I-2-Methyl-4-bromopyridine ingasetyenziselwa njengento eluhlaza kunye ne-reagent kwi-organic synthesis.
Indlela:
- I-2-Methyl-4-bromopyridine inokufumaneka ngokuphendula i-2-methyl-4-pyridine methanol kunye ne-phosphorus tribromide.
- Ngexesha lokuphendula, i-2-methyl-4-pyridine methanol kunye ne-phosphorus tribromide yongezwa kwisitya sokuphendula, umxube wokuphendula ushushu, kwaye i-2-methyl-4-bromopyridine yahlanjululwa yi-distillation kunye nezinye iindlela.
Ulwazi ngoKhuseleko:
- I-2-Methyl-4-bromopyridine inokubangela ukucaphuka kwamehlo, ulusu, kunye nendlela yokuphefumula kwaye kufuneka igwenywe xa isetyenziswa.
-Nxiba iliso elikhuselayo, iiglavu kunye nokhuseleko lokuphefumla xa usebenzisa.
- Yinto enetyhefu kwaye kufuneka igcinwe ngokufanelekileyo kwaye igcinwe kude nemithombo yomlilo kunye nee-oxidizing agents.
- Ukuba i-2-methyl-4-bromopyridine ifakwe okanye ifakwe, funa unyango ngokukhawuleza.
