Isingeniso

I-2,6-dimethylpyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2,6-dimethylpyridine:

 

Ikhwalithi:

I-2,6-Dimethylpyridine iwuketshezi olungenambala olunephunga elinamandla.

 

Sebenzisa:

I-2,6-Dimethylpyridine inezinhlelo zokusebenza ezihlukahlukene:

1. Ingasetshenziswa njenge-catalyst kanye ne-reagent ku-organic synthesis reactions.

2. Isetshenziswa njengento eluhlaza yokulungiswa kwamadayi, ama-fluorescents nezinto eziphilayo.

3. Isetshenziswa njenge-solvent kanye ne-extractant, esetshenziswa kabanzi ekuphenduleni kwamakhemikhali ngobuningi kanye nemboni yezemithi.

 

Indlela:

I-2,6-Dimethylpyridine ivame ukukhiqizwa ngokusabela kwe-acetophenone ne-ethyl methyl acetate.

 

Ulwazi Lokuphepha:

1. Inephunga elimnandi futhi kufanele igwenywe lapho uthintana isikhathi eside futhi ugweme ukuhogela amagesi noma umhwamuko.

2. Amagilavu ​​okuzivikela afanelekile, izibuko nezingubo zokuzivikela kufanele zigqokwe ngesikhathi sokusebenza.

3. Gwema ukuthintana nama-oxidants aqinile nama-asidi aqinile ukuze ugweme ukusabela okuyingozi.

4. Lapho ugcina, isitsha kufanele sivalwe ngokuqinile, kude nomlilo kanye nendawo yokushisa ephezulu.

 

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
