Intshayelelo

I-2,6-dimethylpyridine yi-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-2,6-dimethylpyridine:

 

Umgangatho:

I-2,6-i-Dimethylpyridine iyilwelo olungenambala kunye nevumba elibukhali elibukhali.

 

Sebenzisa:

I-2,6-Dimethylpyridine inezicelo ezahlukeneyo:

1. Ingasetyenziswa njenge-catalyst kunye ne-reagent kwi-organic synthesis reactions.

2. Isetyenziswe njengento ekrwada yokulungiswa kwedayi, i-fluorescents kunye nezinto eziphilayo.

3. Isetyenziswe njenge-solvent kunye ne-extractant, isetyenziswe ngokubanzi kwi-bulk reaction reactions kunye ne-pharmaceutical industry.

 

Indlela:

I-2,6-Dimethylpyridine idla ngokuveliswa ngokuphendula kwe-acetophenone kunye ne-ethyl methyl acetate.

 

Ulwazi ngoKhuseleko:

1. Inevumba elibukhali kwaye kufuneka igwenywe xa udibana ixesha elide kwaye ugweme ukuphefumla iigesi okanye umphunga.

2. Iiglavu ezifanelekileyo zokukhusela, izibuko kunye nempahla yokukhusela kufuneka ifakwe ngexesha lokusebenza.

3. Gwema ukudibana nee-oxidants ezinamandla kunye ne-acids ezomeleleyo ukuphepha ukuphendula okuyingozi.

4. Xa ugcina, isitya kufuneka sivalwe ngokuqinileyo, kude nomlilo kunye nendawo yokushisa ephezulu.

 

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
